RESUMO
OBJECTIVE: The use of basilic vein in iliofemoral revascularizations was previously described in the literature as an autologous option for the treatment of vascular prosthesis infection and as a primary conduit in patients at high risk of infectious surgical complications. However, the publications available include several different indications and are limited to case reports. Therefore, the aim of this study was to evaluate the outcomes of the use of arm veins as a safe and effective autologous alternative for iliofemoral reconstruction in patients with chronic limb-threatening ischemia (CLTI) and at high risk of prosthesis infection. METHODS: We performed a multicenter, retrospective cohort study with 53 consecutive iliofemoral bypasses using arm veins as an alternative conduit. The procedures were performed between November 2013 and November 2021, exclusively for patients with CLTI classified as TASC aortoiliac C or D with increased risk of postoperative surgical infection. Demographic, clinical variables, and outcomes were collected from a prospective database. Main endpoints were amputation-free survival (AFS) and major adverse cardiovascular events. Secondary endpoints included primary and secondary patencies and overall survival. Cox regression analysis was used to identify the predictors of AFS. Postoperative surgical complications and 30-day mortality were also assessed. RESULTS: The mean age was 64.2 ± 8.4 years, with a predominance of male gender. The median follow-up period was 615 days. All patients had CLTI, with a predominance of tissue loss (n = 51; 96.2%) and a median ankle-brachial index of 0.28. The basilic vein was utilized in most procedures (69.8%). Thirty-day major adverse cardiovascular events occurred in five cases (9.4%), and the 30-day mortality rate was 3.8%. The AFS, primary patency, secondary patency, and overall survival in 720 days were 71%, 72%, 89%, and 75%, respectively. Cox regression analysis revealed no association between the variables analyzed for AFS. There was no graft late infection nor pseudoaneurysmal degeneration. CONCLUSIONS: Iliofemoral bypass using arm veins as an autologous conduit proved to be an effective and safe procedure with low incidence of postoperative cardiovascular complications and high rates of AFS in patients with CLTI. Also, this suggests that arm veins can be an interesting and suitable autologous alternative conduit for iliofemoral reconstructions, especially in cases in which a prosthesis should be avoided or when it is not available.
RESUMO
OBJECTIVE: This study aims to evaluate the association between the degree of iliac venous outflow obstruction (IVOO) identified by Intravascular Ultrasound (IVUS) and venous reflux presentation in lower limbs on Duplex Ultrasound (DU). METHODS: Patients with bilateral chronic venous insufficiency, CEAP C3-6 (Clinical-Etiology-Anatomy-Pathophysiology classification), and with Visual Analogic Scale score for pain > 5, underwent DU for reflux evaluation: deep venous system (reflux ≥ 1 s); superficial system, great saphenous vein (GSV) and small saphenous vein (SSV) (reflux ≥ 0.5 s); perforator system (reflux ≥ 0.35s). All patients underwent IVUS in the iliac venous territory. The area of the impaired venous segments was categorized as obstructions< 50% (Cat. 1); 50-79% (Cat. 2), and ≥ 80% (Cat. 3). Venous clinical severity scale (VCSS) and reflux multisegment score (RMS) were assessed. RESULTS: 51 patients (n=102 limbs; 50.53 ± 14.5 years, 6 men) were included. The predominant clinical severity CEAP class was C3 in 54/102 (52.9%) limbs. VCSS mean was 14.3 ± 6.7. Severe RMS (≥ 3) was registered in 63,4% of the limbs. In 51/102 limbs (50%) presented cat. 1, 27/102 (26.5%) cat. 2, and 24/102 (23.5%) cat. 3. Previous DVT was associated with critical obstruction (OR 3.65; 95% CI: 1.29-10.38; p=0.015). Superficial and perforator venous systems had no association with the degree of iliac obstruction. Deep venous reflux (DVR) had a significant association with significative IVOO (obstruction ≥ 50%) (OR 6.44; 95% CI: 2.19-18.93; p=0.001) and critical IVOO (obstruction ≥ 80%) (OR 4.57; 95% CI: 1.70-12.27; p=0.003), and significant linear association with IVOO degree and reflux in femoral veins (p<0.001) and popliteal vein (p=0.008). Significant lesions had 5.76 (95% CI: 2.46-13.50; p<0.001) more odds of happening in the left limb. After a multivariate analysis, DVR remained as predictor for significant and critical obstruction (p<0.003, p< 0.012; respectively). Left limb and previous DVT remained as predictors for IVOO ≥50% and IVOO≥ 80% (p<0.001, p=0.043; respectively) CONCLUSIONS: There is a significant linear association between the degree of iliac venous outflow obstruction and reflux in the deep venous system on DU. Limbs with DVR, severe RMS, loss of respiratory variation on DU, and previous DVT, were more likely to be affected by IVOO ≥ 50%, especially with the left leg involvement.

Iliac vein obstruction occurs in 20-30% of the general population. In patients with severe chronic venous insufficiency, this prevalence can be even higher, reaching 50-90% when the obstruction is investigated using intravascular ultrasound. Less invasive methods, such as venous Duplex Scanning, and even invasive ones such as venography may fail to diagnose the condition. Endovascular treatment of these obstructions is effective, safe, and associated with excellent clinical outcomes and stent patency rates, provided that fundamental anatomical and technical principles are considered and applied.
RESUMO
Resumo A obstrução venosa ilíaca ocorre em 20% a 30% da população. Nos portadores de insuficiência venosa crônica grave, essa prevalência é ainda maior, podendo chegar a 50% a 90% dos pacientes, situação em que essa obstrução é investigada pelo ultrassom intravascular. Métodos diagnósticos menos invasivos, como o Doppler vascular, ou mesmo invasivos, como a flebografia, podem falhar em seu diagnóstico. O tratamento endovascular dessas obstruções tem se demonstrado eficaz, seguro e associado a excelente resultado clínico e de perviedade, desde que princípios anatômicos e técnicos fundamentais sejam considerados e aplicados.

BACKGROUND: Abdominal aortic aneurysm (AAA) is a pathological enlargement of infrarenal aorta close to the aortic bifurcation, and it is an important cause of mortality in the elderly. Therefore, the biomarker identification for early diagnosis is of great interest for clinical benefit. It is known that microRNAs (miRNAs) have important roles via target genes regulation in many diseases. This study aimed to identify miRNAs and their target genes involved in the pathogenesis of AAA. METHODS: Tissue samples were obtained from patients who underwent AAA surgery and from organ donors (control group). Quantitative PCR Array was applied to assess 84 genes and 384 miRNAs aiming to identify differentially expressed targets (AAA n = 6, control n = 6), followed by validation in a new cohort (AAA n = 18, control n = 6) by regular qPCR. The functional interaction between validated miRNAs and target genes was performed by the Ingenuity Pathway Analysis (IPA) software. RESULTS: The screening cohort assessed by PCR array identified 10 genes and 59 miRNAs differentially expressed (≥2-fold change, p<0.05). Among these, IPA identified 5 genes and 9 miRNAs with paired interaction. ALOX5, PTGIS, CX3CL1 genes, and miR-193a-3p, 125b-5p, 150-5p maintained a statistical significance in the validation cohort. IPA analysis based on the validated genes and miRNAs revealed that eicosanoid and metalloproteinase/TIMP synthesis are potentially involved in AAA. CONCLUSION: Paired interactions of differentially expressed ALOX5, PTGIS, CX3CL1 genes, and miR-193b-3p, 125b-5p, 150-5p revealed a potentially significant role of the eicosanoid synthesis and metalloproteinase/TIMP pathways in the AAA pathogenesis.

Objective: The objective of this study was to evaluate the correlation between venous pressure gradients (VPGs) and intravascular ultrasound (IVUS) for the diagnosis of caval-iliac venous obstructions in patients with advanced chronic venous insufficiency. Methods: Fifty patients with advanced chronic venous insufficiency symptoms (Clinical, Etiology, Anatomy, and Pathophysiology class 3 to 6) were prospectively submitted to multiplanar venography (MV) with intravenous pressure measurements and IVUS. The patients' lower limbs were divided accordingly: group I, limbs with <50% obstruction on IVUS (n » 49); and group II, limbs with $50% obstruction on IVUS (n » 51). Receiver operating characteristic curves compared the diagnostic performance of the VPGs. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy assessed the performance of VPGs in categories to determine the presence of significant obstruction. Logistic regression assessed the capacity of the VPGs to identify significant obstruction. Results: The most frequent point of venous compression according to IVUS was the proximal left common iliac vein (70%; P < .05). Group II showed a greater prevalence of transpelvic (group I, 8.2%; group II, 74.5%; P < .001) and paravertebral collaterals (group I, 4.1%; group II, 45.1%; P < .001) on n MV. The femoral vein pressures at rest and after reactive hyperemia as well as the femorocaval gradient after reactive hyperemia (FCG-rh) and the femoral gradient after reactive hyperemia were significantly higher in group II (P » .001, P < .001, P » .002, and P » .006). The FCG-rh and the femoral gradient after reactive hyperemia presented the best diagnostic performance among the VPGs (P » .004 and P » .007) in n the receiver operating characteristic curve analysis, although no significant differences between them were found. All the gradients presented low values of sensitivity (<40%). negative predictive value (<60%). and accuracy (<30%). Logistic regression showed that FCG-rh was significantly independent of MV (OR, 8.1; P » .011) in identifying significant obstructions. Conclusions: There is correlation between the VPGs and significant obstructions with IVUS. However, this correlation does not translate to a good diagnostic performance of these VPGs. Only the FCG-rh added significant information to MV in identifying significant caval-iliac vein obstructions.

OBJECTIVE: Thermoablation has been replacing conventional surgery in the surgical treatment of great saphenous vein (GSV) reflux in patients with lower limb varicose veins; however, thermoablation is expensive. Intravenous electrocoagulation (EC) may, selectively and safely, cause necrosis of the GSV wall, but the clinical results have never been studied. The objective of this study was to compare EC and radiofrequency ablation (RFA) in the treatment of GSV insufficiency, considering efficacy, complications, and effect on quality of life. METHODS: This was a prospective, double-blind, randomized clinical trial. Patients with lower limb varicose veins and GSV reflux confirmed by duplex ultrasound were randomized into two treatment groups: EC and RFA. Patients were followed up at 1 week, 3 months, and 6 months after the procedure. Occlusion of the GSV confirmed by duplex ultrasound was considered the primary outcome, and the rate of complications and improvement in quality of life, using the Aberdeen Varicose Vein Questionnaire score, were the secondary outcomes. RESULTS: Fifty-seven patients were included, with a total of 85 treated GSVs; 43 were treated with RFA and 42 with EC. There was no statistically significant difference between the groups regarding age (P = .264), sex (P = .612), Aberdeen Varicose Vein Questionnaire score (P = .054), and diameter (P = .880) and depth (P = .763) of the treated GSV. In the intraoperative period, immediately after thermoablation, all GSVs treated with EC presented no flow and incompressibility in the treated segment, whereas 12 limbs still had flow in the treated GSV (P < .001) and 9 veins showed compressibility (P < .001) when treated with RFA. The main postoperative complication was paresthesia; however, there was no statistical significance between the groups (P = .320) regarding its presence. Time to return to routine activities was lower in the EC group than in the RFA group (P = .026). There was no difference between the groups at the 3-month (P = .157) and 6-month (P = .157) follow-up in occlusion of the GSV and improvement of the quality of life score (P = .786 and P = .401, respectively). CONCLUSIONS: EC has been shown to be an effective method for ablation of the GSV, with venous occlusion rate, occurrence of complications, and effect on quality of life similar to those with RFA.

The purpose of this study was to determine thesonographic criteria for diagnosis of iliac venous out flow obstruction by assessing the correlation of this method with intravascular ultrasound (IVUS) in patients with advanced chronic venous insufficiency (CVI). The evaluation included 15 patients (30 limbs; age,49.4 % 10.7 years; 1 man) with initial CVI symptoms (Clinicalclass, Etiology, Anatomy, and Pathophysiology [CEAP]classification, CEAP1-2) in group I (GI) and 51 patients (102limbs; age, 50.53 % 14.5 years; 6 men) with advanced CVI symptoms (CEAP3-6) in group II (GII). Patients from bothgroups were matched by gender, age, and race. The Venous Clinical Severity Score was considered. All patients underwent structured interviews and duplex ultrasound (DU) examination, measuring the flow phasicity, the femoral volume flowsand velocities, and the velocity and obstruction ratios in the iliac vein. The reflux multisegment score was analyzed in bothgroups. Three independent observers evaluated individuals inGI. GII patients were submitted to IVUS, in which the area ofthe impaired venous segments was obtained and comparedwith the DU results and then grouped into three categories: obstructions <50%, obstructions between 50% and 79%, andobstructions...

As intervenções endovasculares na artéria femoral superficial para o tratamento da doença arterial oclusiva periférica têm crescido nas últimas décadas. A primeira e a segunda geração de stents na artériafemoral superficial falharam em demonstrar a melhora da perviedade do vaso tratado, devido às altas taxas defratura. O objetivo deste estudo foi avaliar os desfechos clínicos no curto prazo com o uso de stents de nitinolsuperflexíveis de terceira geração no tratamento de lesões ateroscleróticas na artéria femoral superficial. Métodos: Trata-se de um estudo retrospectivo, realizado em único centro, no período de junho de 2013 a maio de 2014. Um total de 27 pacientes foi submetido à angioplastia com stents de nitinol superflexíveis de terceira geração em lesões ateroscleróticas da arterial femoral superficial. Resultados: A média de idades foi de 68 ± 12 anos, 55,6% eram do sexo feminino e 74,1%, diabéticos. Os pacientes foram classificados em TASC B e C em 77,7% dos casos. O sucesso técnico foi de 100%. Houve aumento do índice tornozelo-braquial de 0,35 ± 0,1 pré-intervenção para 0,75 ± 0,2 na alta hospitalar. O seguimento médio dos pacientes foi de 6,7 ± 2,3 meses. A taxa de patência primária foi de 96,3%. A taxa de salvamento de membro foi de 100%. Não ocorreram fraturas de stent documentadas por raios X. Conclusões: A angioplastia com uso de stent de nitinol superflexível de terceira geração demonstrou ser efetiva no tratamento das lesões ateroscleróricas da artéria femoral superficial...
Endovascular interventions in the superficial femoral artery for the treatment of peripheral arterial occlusive disease have increased over the last decades. The first- and second-generation stents in the superficial femoral artery have failed to demonstrate improved patency of the treated vessel due to high fracture rates. The aim of this study was to evaluate the clinical, short-term outcomes of using third-generation superflexible nitinol stents in the treatment of atherosclerotic lesions in the superficial femoral artery. Methods: This was a retrospective study carried out in a single center, from June 2013 to May 2014. A total of 27 patients underwent angioplasty with third-generation superflexible nitinol stents in atherosclerotic lesions of the superficial femoral artery. Results: The mean age was 68 ± 12 years, 55.6% were females, and 74.1% were diabetics. Patients were classified as TASC B and C in 77.7% of cases. Technical success was 100%. There was an increase in the anklebrachial index from 0.35 ± 0.1 before the intervention to 0.75 ± 0.2 at hospital discharge. The mean followupof patients was 6.7 ± 2.3 months. The primary patency rate was 96.3%. The limb salvage rate was 100%. There were no stent fractures documented by X-rays. Conclusions: Angioplasty with third-generation superflexible nitinol stent placement was shown to beeffective in the treatment of atherosclerotic lesions of the superficial femoral artery...

Chronic venous disease (CVD) is progressive and has a high prevalence in the economically active population. Its impact on the quality of life of affected individuals is poorly understood. OBJECTIVE: To test for correlations between the CEAP classification of CVD severity and CVD symptoms and quality of life of affected individuals. METHODS: We investigated 91 lower limbs in 59 patients with CVD (CEAP C1- C6). Patients were assessed with a Visual Analogue Pain Scale (VAPS), the Venous Clinical Severity Score (VCSS) and the SF-36 quality-of-life questionnaire. Spearman correlation coefficients were calculated. RESULTS: There were positive correlations between the CEAP classification and scores for VAPS (0.815, p <0.000), VCSS (0.937, p <0.000), and SF-36 in the dimensions Physical Functioning: -0.791, p <0.000; Role Physical: -0.839; p <0.000; Bodily Pain: -0.684; General Health: -0.617, p <0.000; Role Emotional: -0.691, p <0.000). There was no correlation with Vitality: -0.003, p=0.979; Role Social: -0.188, p=0.740 or Mental Health: -0.085, p=0.421. CONCLUSIONS: There were positive correlations between CEAP and both VAPS and VCSS. Chronic Venous Insufficiency progressively affects quality of life (SF-36). Physical and emotional aspects are more severe at later stages of CVD. Vitality, Mental Health and Role Social can be negatively impacted from the early stages of the disease...
A doença venosa crônica (DVC) é a causa mais frequente dos sintomas vasculares que acometem os membros inferiores. É pouco estudada a relação entre seus sinais clínicos, a intensidade dos sintomas, e a qualidade de vida do indivíduo acometido. OBJETIVOS: Verificar se existe uma relação positiva entre a progressão da doença e a gravidade dos sintomas e a piora na qualidade de vida. MÉTODOS: Avaliamos 91 membros com classificação clínica CEAP entre C1 e C6. Os sintomas foram avaliados através da Escala Visual Analógica de Dor (EVAD), da Escala de Gravidade Clínica dos Sintomas Venosos (EGCSV) e pelo questionário de qualidade de vida SF-36. Foi verificada a presença de correlação entre essas variáveis através do método proposto por Spearman, considerando p significativo quando inferior a 0,05. RESULTADOS: Houve correlação positiva entre a gravidade da doença da DVC (CEAP C1-6) e a EVAD (0,815; p<0,000) e a EGCSV (0,937; p<0,000); observou-se correlação negativa com a SF-36 nos quesitos: Capacidade Funcional (-0,791; p<0,000); Limitação Física (-0,839; p<0,000); Dor (-0,684; p<0,000); Estado Geral de Saúde (-0,617; p<0,000); Aspectos Emocionais (-0,691; p<0,000). Não houve correlação com a Vitalidade (-0,003, p=0,979), Aspectos Sociais (-0,188, p=0,740) e Saúde Mental (-0,085, p=0,421). CONCLUSÕES: Na DVC, existe uma correlação positiva entre a gravidade dos sinais clínicos da doença e a intensidade dos sintomas, e correlação negativa com a qualidade de vida, que é gravemente comprometida, em seus aspectos físicos e emocionais. A vitalidade, a saúde mental e os aspectos sociais são comprometidos já nos estágios iniciais da doença...

Objective: Iliocaval obstruction is associated with venous hypertension symptoms and may predispose to deep venous thrombosis (DVT). Ultrasonography may fail to achieve noninvasive diagnosis of these obstructions. The possibility of using Computed Tomography Venography (CTV) for these diagnoses is under investigation. Methods: Patients with CVI graded at CEAP clinical classes 3 to 6 and previous treatment failure underwent evaluation with CTV. Percentage obstruction was rated by two independent examiners. Obstruction prevalence and its associations with risk factors and CEAP classification were analyzed. Results: A total of 112 limbs were prospectively evaluated. Mean patient age was 55.8 years and 75.4% were women. Obstructions involved the left lower limb in 71.8% of cases and 35.8% of patients reported a medical history of deep venous thrombosis. Overall, 57.1% of imaging studies demonstrated venous obstruction of at least 50% and 10.7% showed obstruction of >80%. The only risk factor that was found to be independently associated with a significantly higher incidence of >50% venous obstruction was a medical history of DVT (p=0.035) (Fisher's exact test). There was a positive relationship between clinical classification (CEAP) and degree of venous obstruction in the limbs studied (Chi-square test for linear trend; p=0.011). Conclusion: Patients with advanced CVI are often affected by obstructions in the iliocaval venous territory and CTV is able to diagnose the degree of obstruction. There is a positive association between degree of obstruction and both previous history of DVT and severity of symptoms of CVI. .
Objetivo: A obstrução ilíaco-cava é associada a sintomas de hipertensão venosa e é um fator de risco para a trombose venosa profunda (TVP). A ultrassonografia pode falhar em seu diagnóstico. Não existe método de "sreening" bem estabelecido. A capacidade da Angiotomografia em realizar esse diagnóstico vem sendo investigada. Método: Pacientes portadores de IVC avançada e com falha no tratamento clínico foram submetidos à Angiotomografia. As imagens foram classificadas quanto ao grau de obstrução por dois investigadores independentes. Foram avaliados a prevalência e o grau de obstrução, e a sua relação com dados demográficos, fatores de risco e sintomas clínicos (CEAP). Resultados: Foram avaliados 112 membros. A idade média dos pacientes foi de 55,8 anos e 75,4% eram mulheres. A obstrução acometia o membro inferior esquerdo em 71,8% e havia história de TVP em 35,8% destes. Em 57,1% dos membros, havia obstrução > 50% e, em 10,7%, a obstrução era > 80%. A história de TVP foi o único fator demográfico com associação positiva com o grau de obstrução (p = 0,035) (teste Exato de Fisher). Houve associação positiva entre a classificação clínica (CEAP) e o grau de obstrução venosa (Teste Qui-quadrado para tendência linear; p=0,011). Conclusão: Pacientes portadores de IVC avançada são frequentemente acometidos por obstrução venosa ilíaco-cava e a Angiotomografia é capaz de identificar o grau dessa obstrução. Existe uma relação positiva entre o grau de obstrução e a classificação clínica, e a história de TVP .

Context: Abdominal aortic aneurysm (AAA) is a condition that is usually asymptomatic, but potentially fatal, and has a prevalence in men over 60 years old ranging from 4.3% to 8%. There are two treatment options available: open surgery (OS) and endovascular treatment (ET). Objective: To compare the results of repairs conducted using these two treatment methods from 2008 to 2013 in a tertiary hospital. Methods: A retrospective analysis comparing 119 patients treated with OS and 219 patients who underwent ET for AAA repair. Results: The ET group was older (71.3 vs. 68.2 years; p<0.001) and had a higher rate of coronary disease (44.7% vs. 27.7%; p=0.002) and a lower ejection fraction (57.6% vs. 64.3%; p<0.001); in turn, the OS group had more chronic obstructive pulmonary disease (16.0% vs. 5.9%; p=0.004) and a smaller proximal infrarenal neck (15.5 mm vs. 23.0 mm; p<0.001). However, there was no difference in ASA classification (American Society of Anesthesiology) (p=0.36). The ET group had less intraoperative bleeding (171 mL vs. 729 mL; p<0.001) and required fewer blood transfusions (11.9% vs. 73.1% p<0.001), and spent shorter stays in both ICU (2.4 vs. 3.5 days; p=0.002) and hospital (5.8 vs. 10.3 days; p<0.001). Thirty-day mortality was similar (OS 5.0% vs. ET 4.1%; p=0.78) and there was also no difference in postoperative complications. The average cost of ET was higher (R$34,277.76 vs. R$4,778.60; p<0.001). Conclusions: Rates of morbidity and mortality were similar, although ET was associated with less bleeding, fewer transfusions and shorter hospital stays, but was more expensive. .
Contexto: O aneurisma de aorta abdominal (AAA) é uma condição frequentemente assintomática, porém potencialmente fatal, cuja prevalência em homens com 60 anos ou mais está entre 4,3% e 8%. Existem duas modalidades de tratamento disponíveis: cirurgia aberta (TA) e endovascular (TE). Objetivo: Comparar os resultados dessas duas modalidades de tratamento, entre 2008 e 2013, em um hospital terciário. Métodos: Análise retrospectiva comparando 119 pacientes submetidos ao TA e 219 pacientes submetidos ao TE, para correção de AAA. Resultados: O grupo submetido ao TE apresentou maior idade (71,3 vs. 68,2 anos; p<0,001) e doença coronariana (44,7% vs. 27,7%; p=0,002), além de menor fração de ejeção (57,6% vs. 64,3%; p<0,001); por sua vez, o grupo submetido ao TA exibiu mais doença pulmonar obstrutiva crônica (16,0% vs. 5,9%; p=0,004) e menor colo proximal infrarrenal (15,5 mm vs. 23,0 mm; p<0,001). Entretanto, não houve diferença na classificação ASA (American Society of Anesthesiology) (p=0,36). O grupo de TE apresentou menor sangramento intraoperatório (171 mL vs. 729 mL; p<0,001), com menor necessidade de hemotransfusão (11,9% vs. 73,1% p<0,001), menor permanência em UTI (2,4 vs. 3,5 dias; p=0,002) e menor tempo de internação hospitalar (5,8 vs. 10,3 dias; p<0,001). A mortalidade em 30 dias foi semelhante (TA 5,0% vs. TE 4,1%; p=0,78), também não havendo diferença nas complicações pós-operatórias. O custo médio do TE foi maior (R$34.277,76 vs. R$4.778,60; p<0,001). Conclusão: As taxas de morbimortalidade foram semelhantes, sendo no TE o sangramento, a necessidade transfusional e a duração da internação hospitalar menores, porém com custo mais elevado. .

Introdução: O manejo das doenças da aorta torácica que envolvem a aorta ascendente, arco aórtico e aorta torácica descendente constituem um desafio técnico e é uma área em constante desenvolvimento e inovação. Objetivo: Analisar os resultados iniciais e a médio prazo do tratamento híbrido das doenças do arco aórtico. Métodos: Estudo retrospectivo de procedimentos realizados no período de janeiro de 2010 a dezembro de 2012, em que foram analisados o sucesso técnico e terapêutico, a morbimortalidade, os desfechos neurológicos, a taxa de vazamentos e de reintervenções. Resultados: Em um total de 95 pacientes tratados por doenças da aorta torácica no período, 18 realizaram o tratamento híbrido e adentraram neste estudo. A idade média foi de 62,3 anos. O sexo masculino esteve presente em 66,7%. O sucesso técnico e terapêutico foi de 94,5% obe 83,3%, respectivamente. A mortalidade perioperatória foi de 11,1%. Não houve óbito durante o acompanhamento de 1 ano. A taxa de reintervenção foi de 16,6%, devido a 2 casos de endoleak tipo Ia e um caso de endoleak tipo 2. Não foi observada oclusão dos enxertos anatômicos ou extra-anatômicos durante o período de seguimento. Conclusão: O tratamento híbrido das doenças do arco aórtico demonstrou ser uma alternativa viável à cirurgia convencional. As taxas de sucesso terapêutico e de reintervenções demonstram a necessidade do seguimento clínico rigoroso desses pacientes a longo prazo. .
Introduction: The management of thoracic aortic disease involving the ascending aorta, aortic arch and descending thoracic aorta are technically challenging and is an area in constant development and innovation. Objective: To analyze early and midterm results of hybrid treatment of arch aortic disease. Methods: Retrospective study of procedures performed from January 2010 to December 2012. The end points were the technical success, therapeutic success, morbidity and mortality, neurologic outcomes, the rate of endoleaks and reinterventions. Results: A total of 95 patients treated for thoracic aortic diseases in this period, 18 underwent hybrid treatment and entered in this study. The average ages were 62.3 years. The male was present in 66.7%. The technical and therapeutic success was 94.5% e 83.3%. The perioperative mortality rate of 11.1%. There is any death during one-year follow- up. The reoperation rates were 16.6% due 2 cases of endoleak Ia and one case of endoleak II. There is any occlusion of anatomic or extra anatomic bypass during follow up. Conclusion: In our study, the hybrid treatment of aortic arch disease proved to be a feasible alternative of conventional surgery. The therapeutic success rates and re- interventions obtained demonstrate the necessity of thorough clinical follow-up of these patients in a long time. .
