RESUMO
Of all thyroid cancers, anaplastic thyroid carcinoma (ATC) has the lowest incidence and worst prognosis. In this report, we describe a 64-year-old female patient who underwent total thyroidectomy and level VI neck dissection for papillary thyroid carcinoma. During follow-up, she showed signs of regional recurrence and underwent extended neck dissection and cervical esophagectomy. Intraoperatively, there was no cleavage plane between the tumor and the common carotid artery (CCA), so a carotid shunt was implanted and en bloc resection, including the affected CCA and esophagus segments was performed followed by vascular bypass with interposition of a great saphenous vein graft. A pathology review found evidence of anaplastic carcinoma. The patient underwent adjuvant treatment and has no signs of locoregional recurrence. Presented with the possibility of carrying out curative surgery with en bloc resection, the vascular surgeon must be prepared for the surgical options.
RESUMO
Resumo O carcinoma anaplásico da tireoide corresponde ao câncer de menor incidência e de pior prognóstico. Neste relato, descrevemos o caso de uma paciente de 64 anos submetida a tireoidectomia total associada a esvaziamento cervical nível VI devido a carcinoma papilífero de tireoide. No seguimento, apresentou sinais de recidiva regional e foi submetida a esvaziamento cervical ampliado e esofagectomia cervical. No intraoperatório, observou-se ausência de plano de clivagem entre o tumor e a artéria carótida comum (ACC) e procedeu-se com implante de shunt carotídeo, resseção em bloco incluindo segmento da ACC e do esôfago acometidos e ponte vascular com interposição da veia safena magna. Foi evidenciado carcinoma anaplásico em revisão de lâmina do exame anatomopatológico. A paciente foi submetida ao tratamento adjuvante e não apresenta sinais de recidiva locorregional. Diante da possibilidade de proceder uma cirurgia curativa com ressecção em bloco, o cirurgião vascular deve estar apto para as opções cirúrgicas.

RESUMO
Carotid artery trauma carries a high risk of neurological sequelae and death. Surgical management of these injuries has been controversial because it entails deciding between repair or ligation of the vessel, for which there is still no true consensus either way. This article proposes a new management strategy for carotid artery injuries based on the principles of damage control surgery which include endovascular and/or traditional open repair techniques. The decision to operate immediately or to perform further imaging studies will depend on the patient's hemodynamic status. If the patient presents with massive bleeding, an expanding neck hematoma or refractory hypovolemic shock, urgent surgical intervention is indicated. An altered mental status upon arrival is a potentially poor prognosis marker and should be taken into account in the therapeutic decision-making. We describe a step-by-step algorithmic approach to these injuries, including open and endovascular techniques. In addition, conservative non-operative management has also been included as a potentially viable strategy in selected patients, which avoids unnecessary surgery in many cases.
El trauma de la arteria carótida tiene una alta probabilidad de muerte y de secuelas neurológicas. El manejo quirúrgico es objeto de controversia porque se tiene que decidir entre reparar la arteria carótida o ligarla, para lo cual aún no existe un consenso. El objetivo de este artículo es proponer una nueva estrategia de manejo para el trauma de la arteria carótida con los principios de la cirugía de control de daños y el uso de técnicas como el reparo endovascular o el manejo conservador. La decisión de operar el paciente inmediatamente o realizar estudios imagenológicos dependerá del estado hemodinámico del paciente. Si el paciente presenta sangrado masivo, hematoma expansivo o choque hipovolémico refractario, una intervención quirúrgica urgente esta indicada. Un déficit del estado neurológico al ingreso es un marcador de mal pronóstico en estos casos e influye en la toma de decisiones. Se describe el paso a paso del reparo vascular abierto y se incluye las estrategias de manejo tanto endovasculares como abiertas. Adicionalmente, el manejo conservador también ha sido incluido como una estrategia viable en pacientes seleccionados, evitando cirugías innecesarias.

The present study aims to develop an integrative review about pseudoaneurysms after traumatic facial trauma, through the analysis of its etiology, type of fracture, signs and symptoms, time elapsed between the trauma and the exposure of signs and symptoms, and treatment performed in these cases. Furthermore into the report, there are 3 clinical cases that occurred in the Buccomaxillofacial Surgery and Traumatology service of Hospital da Restauração Recife/PE. The study was carried out in 2 phases, first, a digital research about post-traumatic craniofacial pseudoaneurysm was performed in the following databases "MEDLINE/PubMed," "Scielo" and "Scopus," in September 2019, with 5 articles being included. In the second, 3 cases of patients with high-impact facial trauma who developed pseudoaneurysm of the internal carotid artery were reported. The average age of the patients was 35.6 years, all patients were male (100%), the majority (60%) being victims of an automobile accident, 3 patients (60%) suffered craniofacial trauma and 2 (40%) had trauma only to the face, most of them had symptoms later on due to the trauma, in 80% of cases the therapy instituted was embolization. Cases of high-impact craniofacial traumas, which present epistaxis and/or ophthalmological alterations correlated to fractures, should be carefully evaluated, determining a better prognosis for the patient.

BACKGROUND: Angioplasty using a carotid stent is a treatment modality for carotid stenosis, with results similar to those obtained with endarterectomy, as demonstrated by important studies. The increasing use of this procedure has also led to a larger number of reports of complications, stent fractures among those. Stent fracture is a rare manifestation and hence needs further studying so that its actual prevalence can be determined, as well as its associated risk factors and proper clinical management. The current study reports the case of a patient who had previously undergone angioplasty with a carotid stent and, after an automobile accident, presented with a stent fracture and distal embolization of fragments thereof with neurological manifestation. CASE DESCRIPTION: A male patient, 40 years old, presented with a history of previously stent carotid angioplasty. He had been involved in an automobile accident and suffered a stent fracture with distal fragment migration. As he was an asymptomatic patient (NIHSS 0, Rankin zero), we opted for a conservative treatment with oral anticoagulant. CONCLUSION: Angioplasty is an effective treatment for extracranial atherosclerosis and, albeit rare, stent fractures can result in the migration of fragments thereof. This occurrence should be suspected in patients who have sustained severe neck injuries due to sudden deceleration and may be associated with thromboembolism.
RESUMO
Carotid artery dissection is a significant cause of stroke in young patients. It may be asymptomatic and go undiagnosed, or minimal transient manifestations may follow, commanding a higher index of suspicion than ordinarily exists to avoid misdiagnosis. Reported herein is a 27-year-old man who suffered extracranial internal carotid artery dissection while practicing a Brazilian Jiu-Jitsu submission maneuver. The patient's condition suddenly deteriorated one week later due to distal embolization and stroke. Despite endovascular treatment, with stenting of the cervical carotid artery, neurologic deficits remained. Of note, the objective in martial arts, which is to kill or incapacitate, has yet to be fully tempered in transitioning to sport. Brazilian Jiu-jitsu, a relatively new and fast-growing form of martial art, places emphasis on submission maneuvers. Related injuries are not common knowledge and are poorly described in the literature. This account is intended to shed light on the risk of this discipline. Through education and improved supervision, vascular injuries of this nature and the potentially lethal or disabling consequences may thus be prevented in young athletes.
RESUMO
La fistula carótido-cavernosa es una comunicación anómala entre la arteria carótida y el seno cavernoso que provoca un shunt arteriovenoso patológico y cuyo origen es traumático o espontáneo. Las manifestaciones clínicas están relacionadas con el cambio de dirección del drenaje venoso y del flujo sanguíneo a través de la fístula e incluyen síntomas oculares tales como quemosis, exoftalmos y soplo orbitario, además de manifestaciones neurológicas como infartos venosos y hemorragias intracerebrales. Su presencia se confirma mediante la angiografía por sustracción digital (ASD) y la clasificación generalmente aceptada se basa en la propuesta por Barrow. El tratamiento endovascular ha sido el enfoque terapéutico preferido durante las últimas dos décadas; sin embargo, el tratamiento quirúrgico sigue siendo una opción cuando aquél falla o no está disponible. Se reporta el caso de una paciente de 71 años de edad, con antecedente de traumatismo cráneo-encefálico en la que se diagnósticó fístula carótido-cavernosa izquierda y síntomas neuro-oftalmológicos bilaterales asociados a un infarto venoso a nivel temporal izquierdo. La paciente fue intervenida quirúrgicamente y presentó una evolución clínica favorable.
The carotid-cavernous fistula is an abnormal communication between the carotid artery and the cavernous sinus that induces a pathological arterio-venous shunt, and whose origin may be traumatic or spontaneous. Its clinical symptoms are related to changes in the direction of the venous drainage and blood flow through the fistula, and include ocular symptoms as chemosis, exophthalmos and orbital murmur besides neurological manifestations such as venous infarctions and intracerebral hemorrhage. Its presence is confirmed by digital subtraction angiography and the generally accepted classification is based on Barrow'se proposal. Endovascular treatment has been the preferred treatment approach for the past two decades; however, surgical treatment remains an option when the former fails or is not possible. The case of a 71 year-old woman with a history of traumatic brain injury is reported: the patient was diagnosed with carotid-cavernous fistula and bilateral neuro-ophthalmic symptoms associated with left temporal venous infarction, and underwent surgical treatment with a favorable clinical outcome.
RESUMO
ABSTRACT Objective: to evaluate the endovascular treatment of vascular lesions of the cavernous segment of the internal carotidartery (ICA) performed at our institution. Methods: we conducted a descriptive, retrospective and prospective study of patients with aneurysms of the cavernous portion of the ICA or with direct carotid-cavernous fistulas (dCCF) undergoing endovascular treatment. Results: we included 26 patients with intracavernous aneurysms and ten with dCCF. All aneurysms were treated with ICA occlusion. Those with dCCF were treated with occlusion in seven cases and with selective fistula occlusion in the remaining three. There was improvement of pain and ocular proptosis in all patients with dCCF. In patients with intracavernous aneurysms, the incidence of retro-orbital pain fell from 84.6% to 30.8% after treatment. The endovascular treatment decreased the dysfunction of affected cranial nerves in both groups, especially the oculomotor one. Conclusion: the endovascular treatment significantly improved the symptoms in the patients studied, especially those related to pain and oculomotor nerve dysfunction.
RESUMO Objetivo: avaliar o tratamento endovascular de lesões vasculares da artéria carótida interna (ACI), segmento cavernoso, realizado na Santa Casa de São Paulo. Métodos: estudo descritivo, retrospectivo e prospectivo, de pacientes com aneurisma da porção cavernosa da ACI ou com fístulas carótido-cavernosas diretas (FCCd) submetidos a tratamento endovascular. Resultados: foram incluídos 26 pacientes com aneurismas intracavernosos e dez com FCCd. Todos os aneurismas foram tratados com oclusão da ACI. Os com FCCd foram tratados com oclusão, em sete casos, e com oclusão seletiva da fístula nos outros três. Houve melhora da dor e proptose ocular em todos os pacientes com FCCd. Nos pacientes com aneurisma intracavernoso, a incidência de dor retro-orbitária caiu de 84,6% para 30,8% após o tratamento. Após o tratamento endovascular houve uma melhora importante da disfunção de nervos cranianos afetados em ambos os grupos, sobretudo no nervo oculomotor. Conclusão: o tratamento endovascular trouxe melhora para os pacientes deste estudo, especialmente nos critérios dor e acometimento do nervo oculomotor.

SUMMARY Carotid cavernous fistulas (CCFs) are abnormal connections between the carotid artery and the cavernous sinus. They are considered direct when there is a direct connection between the internal carotid artery and the cavernous sinus. These cases are generally traumatic. Direct CCFs are high-flow lesions, possibly related to intracranial bleeding, visual loss, corneal exposure or even fatal epistaxis. Treatment of such lesions is, thus, always recommended. The ideal treatment for direct CCF is to exclude the fistula from circulation, preserving the carotid flow. This can be attained using diverse endovascular techniques. The objective of the present article is to review the current techniques for treatment of direct CCFs, with special attention to the currently available endovascular treatment options.
RESUMO As fístulas carotidocavernosas (FCC) são comunicações anormais entre a artéria carótida e o seio cavernoso. Elas são consideradas diretas quando há uma comunicação direta entre a artéria carótida interna e o seio cavernoso. Nesses casos, são geralmente traumáticas. As FCC diretas são lesões de alto fluxo, podendo estar relacionadas a sangramento intracraniano, perda visual, exposição corneana ou até mesmo a epistaxe fatal. Seu tratamento é sempre indicado. O tratamento ideal da FCC direta é a exclusão da fístula da circulação, com preservação do fluxo carotídeo. Isso pode ser obtido por meio de técnicas endovasculares diversas. O objetivo do presente artigo é realizar uma revisão sobre as FCC diretas, com especial enfoque nas opções de tratamento endovascular disponíveis na atualidade.

Lesiones accidentales de la arteria carótida son complicaciones poco frecuentes de diversos procedimientos diagnósticos y terapéuticos. Representan una condición grave y potencialmente mortal si el tratamiento no se realiza adecuadamente. Un paciente de sexo femenino, 45 años de edad, que ingresó en el servicio de Otorrinolaringología con queja de la disminución de la agudeza auditiva y acúfenos en el oído izquierdo. La resonancia magnética encefálica mostro una formación expansiva / infiltrativa a comprometer desde la nasofaringe izquierda hasta la base del cráneo, con la participación de la arteria carótida interna (ACI) en el mismo lado en su segmento petroso. Durante el procedimiento de biopsia, se produjo una laceración en la carótida derecha intracavernosa con sangrado abundante. Se realizó un taponamiento local y el paciente fue remitido a la angiografía cerebral que mostró un seudoaneurisma en la arteria carótida interna derecha en su segmento cavernoso. Después de una prueba de oclusión, la ACI derecha fue ocluida por 2 globos. Tres semanas después, el estado del paciente mostró empeoramiento progresivo de la agudeza visual, proptosis ocular, hiperemia conjuntival y la restricción del movimiento ocular en el ojo derecho. Una nueva angiografía fue realizada y mostró la persistencia de la oclusión de la ACI en su origen y un seudoaneurisma asociado con fístula carótido-cavernosa derecha, que se opacificado después de la inyección de contraste en la ACI izquierda, a través de la arteria comunicante anterior. El paciente fue sometido a un nuevo tratamiento endovascular con resolución de la lesión. Laceración de ACI durante la cirugía transesfenoidal es una complicación rara y potencialmente fatal. La prevención es el mejor tratamiento para cualquier lesión accidental. La utilización de técnicas endovasculares ha permitido para el tratamiento satisfactorio de esta condición.
Accidental carotid artery lesions are uncommon complications from diverse diagnostic and therapeutic procedures. It represents a grave and potentially lethal condition if treatment is not adequately performed. A female patient, 45 years old, who was admitted to the Otolaryngology service complaining of diminished auditory acuity and tinnitus in the left ear. The encephalic magnetic resonance imaging (MRI) showed an expansive/infiltrative formation compromising the left nasopharynx to the skull base, involving the ipsilateral internal carotid artery (ICA) in its petrous segment. During the biopsy procedure, there was a right intracavernous ICA laceration with copious bleeding. A local tamponade was performed and the patient was referred to cerebral angiography (CAG), which showed a right ICA pseudoaneurysm in its intracavernous segment. After a balloon occlusion test, the right ICA was occluded by 2 balloons. Three weeks after, the patients condition showed progressive worsening of visual acuity, occular proptosis, conjuctival hyperemia and occular movement restriction in the right eye. A new CAG was performed and showed persistence in the right ICA occlusion in its origin and an intracavernous pseudoaneurysm associated with ipsilateral carotidcavernous fistula, which became opacified after contrast injection in left ICA, through the anterior communicating artery. The patient was submitted to a new endovascular treatment with lesion resolution. ICA laceration during transsphenoidal surgery is a rare and potentially fatal complication. The prevention is the best treatment for any accidental lesion. Utilization of endovascular techniques has allowed for satisfactory treatment of this condition.

Los pseudoaneurismas son dilataciones debidas a la disrupción de una o más capas de la pared arterial, con fuga sanguínea a través del defecto que está contenida por el tejido más externo e intacto de las capas media y adventicia. El reparo de los pseudoaneurismas debe realizarse para reducir el riesgo complicaciones. Tradicionalmente el manejo de elección en este tipo de lesiones se realizaba quirúrgicamente, con mayor probabilidad de sangrado o lesión neurológica. En la actualidad el manejo endovascular es de elección en pacientes seleccionados. En este artículo se reportan dos casos, para demostrar las diferentes técnicas de tratamiento endovascular en pseudoaneurismas de origen traumático.
Pseudoaneurysms are dilatations due to a disruption of one or more layers of an arterial wall with blood leakage through the defect that is contained by the outer tissue layers of an intact media and adventitia. A pseudoaneurysm must be repaired to avoid the risk of complications. Traditionally they were repaired surgically with a greater risk of bleeding and nerve injury At present, endovascular management is preferred in selected patients. This article reports two cases to illustrate the different techniques of endovascular treatment oftraumatic pseudoaneurysms.

Introdução: As lesões contusas de artérias carótidas e vertebrais (LCCV) não são muito frequentes, porém podem apresentar repercussões graves. A incidência desse tipo de lesão é difícil de ser avaliada porque os doentes podem estar neurologicamente assintomáticos quando atendidos no pronto socorro ou podem apresentar sintomas que são atribuídos ao trauma de crânio ou a outras lesões associadas. Estatísticas recentes apontam uma incidência de 0,24% a 0,33% em doentes traumatizados portadores de algum sintoma neurológico. No Brasil não existem trabalhos de nosso conhecimento que tenham estudado a incidência das LCCV. Por outro lado, a real morbidade e mortalidade das LCCV não estão claramente determinadas, nem mesmo na literatura internacional. Os objetivos deste estudo foram: a) avaliar a incidência de LCCV em 100 doentes vítimas de trauma contuso submetidos à angiotomografia cervical, utilizando parâmetros obtidos da avaliação clínica inicial e das tomografias de crânio e da região cervical e b) verificar quais os critérios de indicação da angiotomografia cervical que mais se correlacionam com a presença de LCCV no serviço de trauma de hospital quaternário brasileiro. Material e Método: Durante o período de trinta meses a partir de julho de 2006, todos os doentes admitidos no Pronto-Socorro do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, com trauma cervical fechado, com potencial risco de lesão dos vasos cervicais apresentando défice neurológico não justificado pela tomografia computadorizada de crânio, infarto cerebral, hematoma cervical estável, epistaxe volumosa, anisocoria/sinal de Horner, escore na escala de coma de Glasgow abaixo de 8 sem achados justificativos pela tomografia, fratura de coluna cervical, fratura de base de crânio, fratura de face (Le Forte II ou III), sinal do cinto de segurança acima da clavícula, frêmito ou sopro cervical, foram incluídos no estudo...
Background: Blunt trauma of the carotid and vertebral arteries (LCCV) are infrequent, but may have serious repercussions. The incidence of this type of injury is difficult to evaluate as many patients are neurologically asymptomatic when assisted in emergency rooms, or with symptoms attributed to cranium trauma or to other associated injuries. Recent statistical data show an incidence of 0.24% to 0.33% traumatized patients that carry some neurological symptom, we are not aware of any papers in Brazil that have studied the occurrence of LCCV. On the other hand, the real morbidity and mortality are not clearly determined, not even in the international literature. The objectives of the current study were: a) to evaluate the incidence of carotid and vertebral artery injuries in 100 patients with blunt trauma subjected to cervical angiography, using parameters obtained from the initial clinical evaluation and tomography of the patients and b) to verify which criteria for recommending cervical angiography are most related to the presence of LCCV in the trauma services section in a Brazilian quaternary care hospital. Method: During thirty months, starting in July 2006, all patients admitted in the emergency room of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, with blunt cervical trauma, with potential risk of injuries to cervical vessels that presented neurological deficit unexplained after cranial CT scan, cerebral infarction, stable cervical haematomas, severe epistaxis, anisocoria/sign of Horner`s syndrome, Glasgow coma scores bellow 8 that are not explained by CT scan, cervical spine fracture, basilar skull fracture, facial fracture (Le Forte II or III), seatbelt signals above the clavicle, cervical hum or bruit were included in the study.
