Revascularização Infrainguinal Híbrida em Isquémia Crítica

A introdução de técnicas endovasculares na rotina dos serviços de Cirurgia Vascular permitiu alargar o leque de opções terapêuticas nas diversas áreas de intervenção da especialidade. A revascularização endoluminal pode ser utilizada como complemento às técnicas cirúrgicas convencionais. Foi realizada pontagem com enxerto protésico femoro-popliteu supra-genicular com e PTFE e seguidamente colocado um introdutor no próprio enxerto. Consegue-se um acesso simplificado a lesões dos vasos distais enquanto se oferece uma revascularização eficaz do sector femoro-popliteu. A revascularização distal foi realizada utilizando angioplastia e colocação de stent conforme os casos, de modo a conseguir fluxo contínuo em pelo menos uma das artérias tibiais ou na artéria peroneal. O objectivo deste tipo de intervenção é permitir a revascularização do sector femoro-popliteu de forma eficaz e seguidamente conseguir fluxo contínuo até pelo menos uma artéria do pé. Este tipo de intervenção pode ser especialmente atractivo para doentes em grau IV de Leriche-Fontaine e na ausência de enxerto venoso autólogo de qualidade.

Reparação Híbrida do Arco Aórtico: Experiência Inicial do Hospital de Santa Marta

Objectives: To retrospectively review the hybrid treatment of the aortic arch with supra-aortic debranching and endo- vascular stent-graft repair in a single institution. Methods: From 2007 to 2010, all patients submitted to aortic debranching procedures were entered into a prospective database analysis. For the present study, only patients with sealing zones 0 and 1, according to the Ishimaru classification, were included. Procedure-related morbimortality was analysed for the open and endovascular procedures. Results: During the study period, we electively performed 6 total aortic debranching and 4 partial aortic debranching procedures in 10 patients. According to the etiology the indications were: 6 aortic arch aneurysms, 2 post-dissection aneu- rysms, 1 false aneurysm and 1 type I endoleak following TEVAR. The proximal sealing zone was Ishimaru zone 0 in six patients and zone 1 in four patients. The TEVAR procedure was delayed in all patients with a completion success of 80% (1 patient died from ruptured aortic aneurysm; 1 patient denied the second procedure and was lost to follow-up). The 30d mortality rate was 10% (patient mentioned above). The main morbidity was: 1 axillar venous thrombosis, 1 case of subclinical myocardial infarction, 1 case of terminal renal insufficiency and 1 case of prolonged ventilation. No permanent cerebral or peripheral neurologic deficit was noted. Conclusions: The hybrid repair of the aortic arch is a feasible and reproducible procedure, and our results are similar to the previously published series. Medium and long-term results are necessary to confirm whether the technique can be regarded as a safe alternative to open surgery in high-risk patients.

The Hybrid Approach for Palliation of Hypoplastic Left Heart Syndrome: Intermediate Results of a Single-Center Experience

INTRODUCTION: Hypoplastic left heart syndrome (HLHS) is a major cause of cardiac death during the first week of life. The hybrid approach is a reliable, reproducible treatment option for patients with HLHS. Herein we report our results using this approach, focusing on its efficacy, safety and late outcome. METHODS: We reviewed prospectively collected data on patients treated for HLHS using a hybrid approach between July 2007 and September 2014. RESULTS: Nine patients had a stage 1 hybrid procedure, with seven undergoing a comprehensive stage 2 procedure. One patient completed the Fontan procedure. Five patients underwent balloon atrial septostomy after the hybrid procedure; in three patients, a stent was placed across the atrial septum. There were three deaths: two early after the hybrid procedure and one early after stage two palliation. Overall survival was 66%. CONCLUSIONS: In our single-center series, the hybrid approach for HLHS yields intermediate results comparable to those of the Norwood strategy. The existence of dedicated teams for the diagnosis and management of these patients, preferably in high-volume centers, is of major importance in this condition.
