RESUMO
Abstract Idiopathic popliteal artery pseudoaneurysms are exceedingly rare, posing significant diagnostic challenges due to their elusive etiology. This report presents the case of a 78-year-old female with no history of trauma or orthopedic procedures who was diagnosed with a large pulsatile mass in the right popliteal fossa. Arteriography confirmed a popliteal artery pseudoaneurysm. Despite extensive clinical evaluation, no causative factors were identified, suggesting an idiopathic diagnosis. The patient underwent open surgical repair using a posterior approach, during which the popliteal artery defect was closed using a bovine pericardium patch. Postoperative follow-up revealed proximal patch stenosis, necessitating angioplasty. This case underscores the need for comprehensive diagnostic evaluation of atypical pseudoaneurysm presentations and highlights the complexities involved in managing idiopathic cases, emphasizing the importance of postoperative follow-up to address potential complications.
Resumo Pseudoaneurismas idiopáticos da artéria poplítea são extremamente raros, apresentando desafios diagnósticos significativos devido à sua etiologia desconhecida. Este relato apresenta uma paciente de 78 anos, sem histórico de trauma ou procedimentos ortopédicos, diagnosticada com uma grande massa pulsátil na fossa poplítea direita. A arteriografia confirmou um pseudoaneurisma da artéria poplítea. Apesar de uma avaliação clínica extensa, nenhum fator causal foi identificado, levando ao diagnóstico idiopático. A paciente foi submetida a reparo cirúrgico aberto usando uma abordagem posterior, e o defeito da artéria poplítea foi fechado com um remendo de pericárdio bovino. O acompanhamento pós-operatório revelou estenose proximal do remendo, necessitando de angioplastia. Este caso evidencia a necessidade de avaliações diagnósticas abrangentes em apresentações atípicas de pseudoaneurisma e destaca as complexidades do manejo de casos idiopáticos, enfatizando a importância do acompanhamento pós-operatório para abordar complicações potenciais.
RESUMO
Objective To review knee magnetic resonance imaging (MRI) scans for the analysis of the location of neurovascular structures (NVSs), and to define the risk of bicortical fixation. Methods Distances between the posterior cortex and the popliteal NVSs were measured on the MRI scans of 45 adolescents (50 knees) at 3 levels (C1: center of the proximal tibial epiphysis; C2: 10 mm distal to the physis; and C3: 20 mm distal to the physis). The NVSs located between 5 mm and 10 mm from the incision were considered in a zone of moderate risk for damage, while those less than 5 mm from the incision were considered in a zone of high risk for damage, and those more than 10 mm from the incision were considered to be in a zone of low risk for damage. The independent Student t -test was used for the comparison of the NVS distance 0with gender, skeletal maturity, and the tibial tubercle-trochlear groove (TT-TG) distance. Values of p < 0.05 were regarded as statistically significant. Results The path of the C1 screw posed an increased risk of damage to the popliteal artery and vein compared with other screw paths ( p < 0.001). The popliteal artery has a high risk of damage at the level of C1 (4.2 ± 2.2mm), and a moderate risk at C2 (9.6 ± 2.4mm), and the popliteal vein has a moderate risk at C1 (6.0 ± 2.7 mm), and a low risk at C2 and C3 (10.8 ± 3.1mm, and 12.05 ± 3.1mm respectively). The C3 position presented the lowest risk of damage to these structures ( p < 0.001). The distance between the posterior tibial cortex and the posterior tibial nerve was < 15 mm at the 3 levels analyzed (C1: 11.0 ± 3.7 mm; C2: 13.1 ± 3.8 mm; and C3: 13 ± 3.9 mm). Conclusions The present study clarifies that the popliteal vessels are at risk of injury during tibial tubercle screw fixation, particularly when drilling the proximal tibial epiphysis. Monocortical drilling and screw fixation are recommended for the surgical treatment of tibial tubercle fractures. Level of Evidence III Diagnostic study.
RESUMO
Heterotopic ossification (HO) is the abnormal formation of extra-skeletal bone in soft tissue, which can occur after trauma or surgery. HO in joints can cause pain, hinder mobility, and compress surrounding nerves and blood vessels. We present an unusual case of arterial insufficiency caused by HO in the right popliteal fossa.

Resumo Objetivo Revisar estudos de ressonância magnética (RM) do joelho para análise da localização das estruturas neurovasculares (ENVs) e definição do risco de fixação bicortical. Métodos As distâncias entre o córtex posterior e as ENVs poplíteas foram medidas nas RMs de 45 adolescentes (50 joelhos) em 3 níveis (C1: centro da epífise proximal da tíbia; C2:10 mm distalmente à fise e C3: 20 mm distalmente à fise). Considerou-se que as ENVs entre 5mme10mmda incisão estavam na zona de risco moderado de lesão, as ENVs a menos de 5 mm da incisão, na zona de alto risco de lesão, e as ENVs a mais de 10 mm da incisão, na zona de baixo risco de lesão. O teste t de Student independente foi usado para comparar a distância até as ENVs com o gênero, a maturidade esquelética e a distância entre a tuberosidade tibial e a garganta (fundo) da tróclea (TT-GT). Valores de p < 0,05 foram considerados estatisticamente significativos. Resultados A trajetória do parafuso em C1 apresentou maior risco de lesão à artéria e à veia poplítea em comparação com outras trajetórias (p < 0,001). A artéria poplítea apresenta risco de lesão alto em C1 (4,2 ± 2,2 mm) e moderado em C2 (9,6 ± 2,4 mm), e a veia poplítea tem risco moderado em C1 (6,0±2,7 mm) e baixo em C2 e C3 (10,8±3,1 mm e 12,05±3,1mm, respectivamente). A posição C3 apresentou o menor risco de lesão dessas estruturas (p < 0,001). A distância entre o córtex tibial posterior e o nervo tibial posterior foi inferior a 15 mm nos 3 níveis analisados (C1: 11,0±3,7mm; C2: 13,1±3,8 mm; e C3: 13±3,9mm). Conclusões Este estudo esclarece que os vasos poplíteos correm risco de lesão durante a fixação do parafuso na tuberosidade tibial, principalmente durante a perfuração da epífise proximal da tíbia. A perfuração monocortical e a fixação com parafusos são recomendadas para o tratamento cirúrgico das fraturas da tuberosidade tibial. Nível de Evidência III Estudo diagnóstico.

Background: Despite significant improvements in outcomes, traumatic arterial limb injuries remain a significant cause of limb loss and mortality. Objectives: This study sought to identify predictors of mortality and major amputation in patients undergoing revascularization after femoropopliteal arterial trauma. Methods: This was a retrospective review of a trauma registry from an urban trauma center in Brazil. All patients admitted to our hospital with a femoropopliteal arterial injury from November 2012 to December 2017 who underwent vascular reconstruction were included. Univariate analyses and logistic regression analyses were conducted to identify factors independently associated with the primary outcome of amputation and the secondary outcome of mortality. Results: Ninety-six patients were included. Eleven patients (11.5%) had an amputation and 14 (14.6%) died. In the logistic regression model for amputation, patients with ischemia duration greater than 6 hours were approximately 10 times more likely to undergo an amputation compared to those with ischemia duration less than or equal to 6 hours (adjusted odds ratio (AOR) [95% confidence interval (CI)]: 9.6 [1.2-79.9]). The logistic regression model for mortality revealed that patients with ischemia duration greater than 6 hours were approximately 6 times more likely to die compared to those with ischemia duration less than or equal to 6 hours (AOR [95% CI]: 5.6 [1.3 to 24.7). Conclusions: Ischemia duration remains the most important factor independently associated with limb loss and mortality for patients undergoing femoropopliteal arterial revascularization after traumatic injuries. Physiological status on admission and trauma scores are also important.
Contexto: As lesões arteriais traumáticas de membros ainda permanecem uma causa significativa de perda de membros e mortalidade, apesar de melhorias significativas observadas nos resultados após a ocorrências dessas lesões. Objetivos: Este estudo buscou identificar preditores de mortalidade e amputações em pacientes submetidos à revascularização após trauma arterial femoropoplíteo. Métodos: Esta é uma revisão de um Registro de Trauma Vascular. Todos os pacientes com lesão arterial femoropoplítea internados em nosso hospital de novembro de 2012 a dezembro de 2017 e submetidos a reconstrução vascular foram incluídos. Análises univariadas, seguidas de análises de regressão logística, foram realizadas para identificar fatores independentemente associados com os resultados primários de amputação e mortalidade. Resultados: Foram incluídos 96 pacientes, com média de 27 anos. O Revised Trauma Score (RTS) foi, em média, 7,152; já o Injury Severity Score (ISS) foi, em média, 15. Onze pacientes (11,5%) tiveram amputação, e 14 pacientes (14,6%) morreram. Observou-se que pacientes com o tempo de isquemia maior que 6 horas apresentaram aproximadamente 10 vezes mais chance de amputação do que aqueles com tempo igual ou menor que 6 horas (intervalo de confiança de 95% [IC95%]: 1,2 a 79,9). O tempo de isquemia maior que 6 horas aumentou em aproximadamente 6 vezes a chance de mortalidade (IC95%: 1,26 a 24,77). A instabilidade hemodinâmica aumentou em 9 vezes a chance de mortalidade (IC95%: 2,36 a 36,67). Conclusões: O tempo de isquemia continua sendo o fator mais importante independentemente associado a amputação e óbito em pacientes submetidos à revascularização arterial femoropoplítea após traumas. O estado fisiológico e os escores de trauma são importantes.
RESUMO
El aneurisma de la arteria poplítea es el principal aneurisma periférico y el segundo en frecuencia después del aneurisma de la aorta abdominal. Su incidencia se desconoce. Posee un patrón característico de presentación que corresponde a personas del sexo masculinos, mayores de 65 años, con múltiples comorbilidades, donde la hipertensión arterial representa la más frecuente. La definición de aneurisma corresponde a una dilatación del 50 por ciento del diámetro del vaso, en el caso de la arteria poplítea, mayor de 1,5 cm. El 50 por ciento de los aneurismas poplíteos resulta asintomático, el resto presenta síntomas isquémicos (trombosis, embolismos periféricos), compresivos y la ruptura. El tratamiento es quirúrgico: convencional (vías medial-posterior) y endovascular. El objetivo del artículo fue presentar este caso por la infrecuencia del aneurisma de la arteria poplítea unilateral. Se trata de un paciente masculino de 62 años, con aumento de volumen localizado a nivel de la fosa poplítea izquierda con latido y expansión a la palpación, diámetro transversal aproximado de 3 cm y longitudinal de 4 cm, presencia de soplo sistólico a la auscultación con diagnóstico ecográfico y arteriográfico de aneurisma de la arteria poplítea izquierda. La evolución del paciente fue satisfactoria y se mantiene bajo seguimiento médico para evaluar la permeabilidad del injerto sintético(AU)
Popliteal artery aneurysm is the main peripheral aneurysm and the second in frequency after abdominal aortic aneurysm. Its incidence is unknown. It has a characteristic presentation pattern that corresponds to male people, over 65 years of age, with multiple comorbidities, where arterial hypertension represents the most frequent. The definition of aneurysm corresponds to a dilation of 50 percent of the diameter of the vessel, in the case of the popliteal artery, greater than 1.5 cm. 50 percent of popliteal aneurysms are asymptomatic, the rest have ischemic symptoms (thrombosis, peripheral embolisms), compression and rupture. Treatment is surgical: conventional (medial-posterior pathways) and endovascular. The objective of the article was to present this case due to the infrequency of the unilateral popliteal artery aneurysm. This is a 62-year-old male patient, with localized volume increase at the level of the left popliteal fossa with heartbeat and expansion on palpation, approximate transverse diameter of 3 cm and longitudinal diameter of 4 cm, presence of systolic murmur at auscultation with ultrasound and arteriographic diagnosis of aneurysm of the left popliteal artery. The patient's evolution was satisfactory and he remains under medical follow-up to evaluate the permeability of the synthetic graft(AU)

RESUMO
Open traumatic lesion of the popliteal artery is relatively rare. Ischemia time longer than 6 h and severity of limb ischemia have been shown to be associated with an increased risk of limb loss. Severe local infection is critical in the presence of major soft tissue trauma or open fractures. We report the case of a young female who suffered a traumatic transection of the popliteal artery associated with an open fracture of the distal tibia and fibula managed by direct vessel reconstruction with an end-to-end repair and skeletal stabilization initially with half-pin external fixation, then replaced by an Ilizarov circular frame. The patient had a very satisfactory outcome, but the fracture healed malunited, later corrected by open reduction and internal fixation with lag-screwing and a neutralization plate.

BACKGROUND: Planning surgical procedures of the lower leg benefits from considering the possibility of an aberrant anterior tibial artery (AATA), but previously published data on the frequency of this anatomic variant shows heterogeneity. We assessed the prevalence of AATA in a Latin American cohort using magnetic resonance imaging (MRI) and compared these with other studies reported in the literature. METHODS: We retrospectively included consecutive patients who had undergone multiplanar knee MRI at a radiology department in Lima, Peru. The MRI protocol included coronal T1 weighted, axial, sagittal and coronal proton density fat-saturated (PDFS) and sagittal T2 weighted images. Two experienced radiologists assessed all images and were blinded to each other's findings. The frequency of the AATA was compared to previous cohorts. A scoping review was undertaken to provide an overview of previously published data on the prevalence of ATAA. RESULTS: We analyzed 280 knee MRI examinations of 253 patients (median age 41 years (IQR 31-52), 53.8% male). The aberrant anterior tibial artery variant was present in 8 of 280 (2.9%) evaluated knees, resulting in a prevalence of 3.2% in our study population. The PDFS sequence in the axial or sagittal orientation was most effective to identify AATA. The frequency of AATA in the reviewed literature using different radiological modalities ranged from 0.4 to 6% (median 1%, IQR (0.5-2.3%). CONCLUSIONS: The AATA is a frequent vascular variant that can be detected by MRI in the preparation of invasive interventions of the lower leg.

Moyamoya disease is a rare disorder that involves the cerebrovascular system. Usually, it leads to occlusion of the arteries of the cerebral system and causes cerebral circulatory complaints. A 48-year-old female patient was admitted to our clinic with intermittent claudication in both legs. Biphasic and monophasic waveform patterns were detected bilaterally in distal (trifurcation arteries) lower extremities with Doppler sonography. The patient therefore underwent systemic vascular examination. Computed tomography angiography revealed bilateral carotid occlusion at the level of supraclinoid segments, and opacifications were detected at the distal segments of the bilateral anterior cerebellar and middle cerebellar arteries. The patient was diagnosed with moyamoya disease, and anticoagulant treatment was started. In conclusion, most previous reports have presented the cerebrovascular involvement of moyamoya disease. However, this disease can involve different peripheral vascular systems and careful and systemic vascular examination is necessary for an exact diagnosis.
A doença de moyamoya é um distúrbio raro que envolve o sistema cerebrovascular. Normalmente, leva à oclusão das artérias do sistema cerebral e causa problemas circulatórios no cérebro. Uma mulher de 48 anos foi admitida em nossa clínica com claudicação intermitente em ambas as pernas. Na ultrassonografia com Doppler, foram detectados padrões de formato de onda bifásico e monofásico nas extremidades inferiores distais (artérias da trifurcação) de forma bilateral. Portanto, realizou-se o exame vascular sistêmico na paciente. A angiografia por tomografia computadorizada revelou oclusão carotídea bilateral no nível dos segmentos supraclinoides, e opacificações foram detectadas nos segmentos distais das artérias cerebelares anteriores e médias de forma bilateral. A paciente foi diagnosticada com doença de moyamoya, e o tratamento anticoagulante foi iniciado. Em conclusão, a maioria dos relatos anteriores apresentou o envolvimento cerebrovascular da doença de moyamoya. No entanto, essa doença pode envolver diferentes sistemas vasculares periféricos, e um exame vascular sistêmico minucioso é necessário para um diagnóstico exato.
RESUMO
Peripheral vascular injuries are uncommon in civilian trauma but can threaten the patient's life or the viability of the limb. The definitive control of the vascular injury represents a surgical challenge, especially if the patient is hemodynamically unstable. This article proposes the management of peripheral vascular trauma following damage control surgery principles. It is essential to rapidly identify vascular injury signs and perform temporary bleeding control maneuvers. The surgical approaches according to the anatomical injured region should be selected. We propose two novel approaches to access the axillary and popliteal zones. The priority should be to reestablish limb perfusion via primary repair or damage control techniques (vascular shunt or endovascular approach). Major vascular surgeries should be managed post-operatively in the intensive care unit, which will allow correction of physiological derangement and identification of those developing compartmental syndrome. All permanent or temporary vascular procedures should be followed by a definitive repair within the first 8 hours. An early diagnosis and opportune intervention are fundamental to preserve the function and perfusion of the extremity.

Se debe identificar los signos sugestivos de lesión vascular y realizar oportunamente maniobras temporales para el control del sangrado.

La prioridad es restablecer la perfusión de la extremidad mediante el reparo primario o técnicas de control de daños (shunt vascular o abordaje endovascular). Los pacientes sometidos a cirugías vasculares mayores deben ser manejados postoperatoriamente en la unidad de cuidados intensivos para corregir las alteraciones fisiológicas e identificar aquellos que desarrollen un síndrome compartimental. Todos los procedimientos vasculares permanentes o temporales deben contar con un reparo definitivo en las primeras 8 horas. El diagnóstico temprano e intervención oportuna son fundamentales para salvaguardar la perfusión y funcionalidad de la extremidad.

The SAFARI technique or Subintimal Arterial Flossing with Antegrade-Retrograde Intervention is an endovascular procedure that allows recanalization of Chronic Total Occlusive (CTO) lesions when conventional subintimal angioplasty is unsuccessful. Retrograde access is usually obtained through the popliteal, anterior tibial, dorsalis pedis artery, or posterior tibial arteries and may potentially provide more options for endovascular interventions in limb salvage. The case of an 81-year-old man with a history of uncontrolled hypertension, diabetes mellitus, and dyslipidemia is presented. He presented with a cutaneous ulcer on the right lower limb with torpid evolution and poor healing. The Doppler ultrasound and arteriographic study revealed a CTO lesion of the popliteal artery that was not a candidate for antegrade endovascular revascularization, but was successfully treated using the SAFARI technique. The patient had no perioperative complications, the wound showed better healing, and he was discharged with an indication of daily dressings and control by an external outpatient clinic.
A técnica SAFARI, ou Subintimal Arterial Flossing with Antegrade-Retrograde Intervention, é um procedimento endovascular que permite a recanalização de lesões por oclusão total crônica (OTC) em caso de fracasso da angioplastia subintimal convencional. O acesso retrógrado é geralmente obtido através da artéria poplítea, tibial anterior, pediosa ou tibial posterior e pode fornecer mais alternativas de intervenções endovasculares para o salvamento do membro. É apresentado o caso de um homem de 81 anos com histórico de hipertenção não controlada, diabetes melito e dislipidemia. Ele apresentava uma lesão ulcerativa cutânea no membro inferior direito com evolução tórpida e má cicatrização. O ultrassom Doppler e o estudo arteriográfico revelaram uma lesão por OTC na artéria poplítea. O paciente não era candidato a revascularização endovascular anterógrada; sendo assim, esta foi realizada com successo utilizando a técnica SAFARI. O paciente não apresentou complicações perioperatórias e recebeu alta com indicação de cuidados diários com a ferida e controle em um ambulatório externo. Além disso, a ferida apresentou melhor cicatrização.

RESUMO
PURPOSE: This technical note aims to show a challenging endovascular treatment approach of a giant and tortuous ruptured popliteal artery aneurism. MATERIALS AND METHODS: An 86-year-old male patient was admitted for acute lower right limb ischemia. Angio-MSCT showed highly calcified superficial femoral artery, with a 180° bend in distal portion, followed by a large popliteal aneurism (63 × 61 mm) with a large extent hematoma (142 × 112 × 104 mm). Endovascular approach was chosen due to high morbidity. RESULTS: Anterior puncture of right superficial femoral artery was performed under ultrasound guidance. Despite various intents, the 0.035 hydrophilic coated wire could not be crossed distally through the aneurism. Retrograde access was performed via tibio-peroneal trunk under fluoroscopic guidance with a micropuncture set. A stiff 0.035â³ Glidewire® was successfully advanced into the proximal portion of the aneurism through a 5F vertebral catheter externalized with a snare from the femoral sheath obtaining a "through-and-through wire" technique. Tightening of both ends of the wire helped gain support and straightened curves. Two stent grafts were implanted with no residual leak at 1 month follow-up. CONCLUSION: Anterograde and retrograde approach was useful to perform a through-and-through wire technique in a challenging case of a tortuous ruptured popliteal artery aneurism.

Introducción. El síndrome de atrapamiento poplíteo es una entidad infrecuente, cuya incidencia oscila entre 0,17 y 3,5 %, representando una de las principales causas de isquemia en miembros inferiores en adultos jóvenes. Suele manifestarse con claudicación intermitente (69 %) o isquemia aguda (26 %), siendo muy rara su presentación con isquemia crítica de miembros inferiores. Caso clínico. Paciente de 30 años quien presentó úlcera subungueal en primer dedo de pie derecho con dolor intenso. En la exploración física no se palpaban pulsos distales y se observó palidez cutánea intensa y frialdad. Se realizó arteriografía donde se observó defecto de repleción de bordes regulares y desplazamiento medial de la arteria poplítea. La resonancia magnética mostró una inserción anómala del gastrocnemio medial, con lo que se hizo diagnóstico de síndrome de atrapamiento poplíteo tipo I. Mediante abordaje posterior se realizó reconstrucción vascular con injerto venoso y sección tendinosa del gastrocnemio medial. En el postoperatorio inmediato el paciente recupera pulso pedio y en el seguimiento a un año el paciente no presenta clínica de isquemia de miembros inferiores, encontrándose el baipás permeable. Discusión. A pesar de su baja incidencia, es importante incluir el síndrome de atrapamiento poplíteo en el diagnóstico diferencial de isquemia en miembros inferiores en adultos jóvenes. Su presentación con isquemia crítica es excepcional, encontrando muy pocos casos publicados en la literatura. La reconstrucción arterial precoz mediante injerto o plastia con material autólogo constituye el tratamiento de elección
Introduction. The popliteal entrapment syndrome is an infrequent entity, whose incidence ranges between 0.17 and 3.5%, representing one of the main causes of lower limb ischemia in young adults. It usually manifests with intermittent claudication (69%) or acute ischemia (26%), being very rare its presentation with critical ischemia of the lower limbs.Clinical case. A 30-year-old patient with a history of smoking, with no other risk factors, who presented with a subungual ulcer on the first right toe. On physical examination, distal pulses are not palpated, intense skin paleness and coldness are observed. Magnetic resonance imaging showed an anomalous insertion of the medial gastrocnemius with extrinsic compression of the popliteal artery, confirming a diagnosis of popliteal entrapment syndrome type I. Vascular reconstruction with venous graft and tendon section of the medial gastrocnemius was performed through a posterior approach. In the immediate postoperative period, the patient recovers a pediatric pulse and in the one-year follow-up the patient does not present symptoms of lower limb ischemia, finding the bypass patent. Discussion. Despite its low incidence, it is important to include popliteal impingement syndrome in the differential diagnosis of lower limb ischemia in young adults. Its presentation with critical ischemia is exceptional, finding very few cases published in the literature. Early arterial reconstruction by graft or plasty with autologous material is the treatment of choice

Abstract The SAFARI technique or Subintimal Arterial Flossing with Antegrade-Retrograde Intervention is an endovascular procedure that allows recanalization of Chronic Total Occlusive (CTO) lesions when conventional subintimal angioplasty is unsuccessful. Retrograde access is usually obtained through the popliteal, anterior tibial, dorsalis pedis artery, or posterior tibial arteries and may potentially provide more options for endovascular interventions in limb salvage. The case of an 81-year-old man with a history of uncontrolled hypertension, diabetes mellitus, and dyslipidemia is presented. He presented with a cutaneous ulcer on the right lower limb with torpid evolution and poor healing. The Doppler ultrasound and arteriographic study revealed a CTO lesion of the popliteal artery that was not a candidate for antegrade endovascular revascularization, but was successfully treated using the SAFARI technique. The patient had no perioperative complications, the wound showed better healing, and he was discharged with an indication of daily dressings and control by an external outpatient clinic.
Resumo A técnica SAFARI, ou Subintimal Arterial Flossing with Antegrade-Retrograde Intervention, é um procedimento endovascular que permite a recanalização de lesões por oclusão total crônica (OTC) em caso de fracasso da angioplastia subintimal convencional. O acesso retrógrado é geralmente obtido através da artéria poplítea, tibial anterior, pediosa ou tibial posterior e pode fornecer mais alternativas de intervenções endovasculares para o salvamento do membro. É apresentado o caso de um homem de 81 anos com histórico de hipertenção não controlada, diabetes melito e dislipidemia. Ele apresentava uma lesão ulcerativa cutânea no membro inferior direito com evolução tórpida e má cicatrização. O ultrassom Doppler e o estudo arteriográfico revelaram uma lesão por OTC na artéria poplítea. O paciente não era candidato a revascularização endovascular anterógrada; sendo assim, esta foi realizada com successo utilizando a técnica SAFARI. O paciente não apresentou complicações perioperatórias e recebeu alta com indicação de cuidados diários com a ferida e controle em um ambulatório externo. Além disso, a ferida apresentou melhor cicatrização.

Abstract Moyamoya disease is a rare disorder that involves the cerebrovascular system. Usually, it leads to occlusion of the arteries of the cerebral system and causes cerebral circulatory complaints. A 48-year-old female patient was admitted to our clinic with intermittent claudication in both legs. Biphasic and monophasic waveform patterns were detected bilaterally in distal (trifurcation arteries) lower extremities with Doppler sonography. The patient therefore underwent systemic vascular examination. Computed tomography angiography revealed bilateral carotid occlusion at the level of supraclinoid segments, and opacifications were detected at the distal segments of the bilateral anterior cerebellar and middle cerebellar arteries. The patient was diagnosed with moyamoya disease, and anticoagulant treatment was started. In conclusion, most previous reports have presented the cerebrovascular involvement of moyamoya disease. However, this disease can involve different peripheral vascular systems and careful and systemic vascular examination is necessary for an exact diagnosis.
Resumo A doença de moyamoya é um distúrbio raro que envolve o sistema cerebrovascular. Normalmente, leva à oclusão das artérias do sistema cerebral e causa problemas circulatórios no cérebro. Uma mulher de 48 anos foi admitida em nossa clínica com claudicação intermitente em ambas as pernas. Na ultrassonografia com Doppler, foram detectados padrões de formato de onda bifásico e monofásico nas extremidades inferiores distais (artérias da trifurcação) de forma bilateral. Portanto, realizou-se o exame vascular sistêmico na paciente. A angiografia por tomografia computadorizada revelou oclusão carotídea bilateral no nível dos segmentos supraclinoides, e opacificações foram detectadas nos segmentos distais das artérias cerebelares anteriores e médias de forma bilateral. A paciente foi diagnosticada com doença de moyamoya, e o tratamento anticoagulante foi iniciado. Em conclusão, a maioria dos relatos anteriores apresentou o envolvimento cerebrovascular da doença de moyamoya. No entanto, essa doença pode envolver diferentes sistemas vasculares periféricos, e um exame vascular sistêmico minucioso é necessário para um diagnóstico exato.

Blunt popliteal vascular injury in the paediatric population is exceedingly rare and in advanced trauma centres the management can be challenging. A case of blunt popliteal artery trauma in a 5 years old requiring distal bypass using reversed saphenous vein is herein described. It is noteworthy to mention the difficulties experienced in a limited resource setting, including limitations in small rural hospitals, inefficient timely transfer to specialised centres, inadequate numbers of highly trained surgeons in subspecialities such as microvascular surgery and finally ineffective support and rehabilitative services.
