Importance of the Internal Thoracic Artery as the Source of Collateral Circulation in CABG Patients with Leriche Syndrome. / Importância da Artéria Torácica Interna como Fonte de Circulação Colateral em Pacientes com CRM com Síndrome de Leriche.

In coronary artery bypass grafting (CABG) the use of the internal thoracic artery (ITA), is a Class I indication for the left anterior descending (LAD) artery. Atherosclerosis is a systemic disease, and peripheral arterial disease (PAD) is an important complicator of CABG, present in about one-third of the patients with coronary disease. In Leriche Syndrome, ITA can be the source of collateral circulation for arteries below the level of occlusion. Its inadvertent use can lead to serious ischemic complications in the dependent territories.

Na cirurgia de revascularização do miocárdio (CRM), o uso da artéria torácica interna (ATI), é uma indicação de Classe I para a anastomose com a artéria descendente anterior esquerda (ADA). A aterosclerose é uma doença sistêmica, além da doença coronariana, um terço dos pacientes possuem doença arterial obstrutiva periférica (DAOP), que é um complicador da CRM. Na Síndrome de Leriche, a ATI pode ser fonte de circulação colateral para artérias abaixo do nível de oclusão. O seu uso inadvertido pode levar a complicações isquêmicas graves nos territórios dependentes.

High prevalence of subclinical atherosclerosis in Brazilian postmenopausal women with low and intermediate risk by Framingham score.

Cardiovascular diseases are the leading cause of mortality among women in several countries. Early detection of subclinical atherosclerosis (SA) could enable the adoption of preventive measures to avoid cardiovascular events. This study aimed to determine the prevalence of SA in Brazilian asymptomatic postmenopausal women in Framingham Risk Score (FRS) low and intermediate groups. Computed tomography (CT) and ultrasound (US) scans were performed in 138 asymptomatic postmenopausal women (56.1 ± 4.9 years of age) to survey for coronary artery and aortic calcification (CT scan) and assess carotid intima-media thickness (CIMT) and identify carotid plaques (US). The mean FRS was 2.64 ± 2.13 %. The prevalence of increased CIMT, carotid plaques, increased CIMT and/or plaques, coronary artery calcification (CAC) >0 and aortic calcification (AC) were, respectively, 45.7, 37.7, 62.3, 23.9 and 45.7 %. Normal imaging tests were found in 22.4 %. SA, defined as at least one abnormal imaging test, was associated with age, FRS, waist-to-rip ratio, systolic and diastolic blood pressure, HDL-c and ApoA1 levels, and ApoA1/ApoB ratio. In logistic regression, SA was associated with higher age (OR 1.108, 95 % CI 1.010-1.215, p = 0.029) and lower ApoA1 levels (OR 0.979, 95 % CI 0.960-0.998, p = 0.029). SA was prevalent in Brazilian postmenopausal women with low and intermediate risk groups (FRS) and was associated with higher age and lower levels of ApoA1. Carotid atherosclerosis was the most common presentation of SA in this group.

Resultados do uso de stents de nitinol superflexíveis na artéria femoral superficial / Outcomes after implantation of superflexible nitinol stents in the superficial femoral artery

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...
