- Consulta de Úlcera de Perna do Hospital de Santa MartaPublication . Garcia, AC; Vasconcelos, L; Valentim, H; Gonçalves, F; Castro, JM; Ferreira, E; Albuquerque e Castro, J; Mota Capitão, LLeg ulcers constitute a highly prevalent pathology in society, and are particularly common in the Angiology and Vascular Surgery outpatient clinic. The prevalence of these patients in this Department result from the fact that 70% of them display superficial and/or deep venous insufficiency of the lower limbs. To address this problem and optimize the therapeutic approaches available to the Chronic Leg Ulcer (CLU) patients, the Department of Angiology and Vascular Surgery has created, in March 2005, an appointment specific to CLU patients. An evaluation protocol was developed, including ulcer characterization, standardization of the conservative treatment, followed by surgical intervention, whenever required. The results obtained were evaluated 18 months after the onset of this protocol. Analysis of the results revealed that the majority of the patients responded positively to the new therapeutic approach, with closure of the ulcer in 43% of the patients and a significant improvement detected for an additional 30%. Furthermore, it was observed that a detailed evaluation of these patients should be regarded as a whole, followed by a standardized and targeted approach, resulting in a particularly successful approach on the treatment of this pathology.
- Falso Aneurisma Supraclavicular Complexo. Caso ClínicoPublication . Gonçalves, F; Valentim, H; Alves, G; Castro, JM; Eça, FA; Albuquerque e Castro, J; Mota Capitão, LOs autores apresentam o caso clínico de um indivíduo do sexo masculino, de 29 anos de idade, saudável, vítima de acidente de viação com traumatismo craniano e torácico, de que resultou um período de internamento em unidade de cuidados intensivos durante cerca de 60 dias. Após a alta hospitalar, referiu o aparecimento de massa pulsátil na região supraclavicular esquerda, associada a crescimento lento e ao aparecimento de dor local e irradiada ao membro superior esquerdo. A investigação realizada demonstrou a existência de um falso aneurisma complexo, com fístulas arterio-venosas associadas, dissecando planos musculares cervicais e envolvendo o plexo braquial. Foi submetido a intervenção cirúrgica que consistiu na laqueação da artéria escapular aferente e da comunicação para a veia jugular interna, com redução franca do fluxo luminal. Foi posteriormente realizada injecção eco-guiada de trombina sob manobra de Valsalva, com trombose subsequente do falso aneurisma. Verificou-se desaparecimento rápido das queixas e redução progressiva do volume de massa (follow-up de 6 meses). Os autores discutem a etiopatogenia, a abordagem cirúrgica e a técnica de exclusão do falso aneurisma por meio de injecção eco-guiada de trombina.
- Reparação Híbrida do Arco Aórtico: Experiência Inicial do Hospital de Santa MartaPublication . Rodrigues, H; Castro, JM; Valentim, H; Laranjeira, A; Ferreira, E; Albuquerque e Castro, J; Fragata, J; Mota Capitão, LObjectives: 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.
- Revascularização Infrainguinal Híbrida em Isquémia CríticaPublication . Gonçalves, F; Valentim, H; Rodrigues, H; Castro, JM; Eça, FA; Albuquerque e Castro, J; Mota Capitão, LA 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.
- A Transposição Valvular nos Doentes com Úlceras dos Membros Inferiores Consequentes a Síndromes Pós-TrombóticosPublication . Albino, JP; Ferreira, E; Castro, JM; Duarte, JN; Gonçalves, D; Sobrinho, G; Meireles, NVenous ulcers in patients with post thrombotic syndromes are complex situations with multiple therapeutic options. They are responsible for high morbidity rates, conservative treatment is very slow and recurrences are very common. Deep venous reconstructive surgery is an alternative, but it should be based on the morphologic and functional aspects of the venous system and only adopted after a very careful study, including venography. The authors describe a morphological "pattern", found in some of these patients and related to the competence of the saphenous femoral junction, rendering possible to perform a valvular transposition. Seven patients with post thrombotic ulcers who have been treated during the last 6 years in which the pattern already described was detect, underwent a transposition of the superficial femoral vein, to the great saphenous vein and when necessary complemented with skyn grafts. Before the operation all patients had ulcers with more than 3 cm in size (3.2-5.4 cm) and with more than 4 months duration (4-16 months). All ulcers healed in the postoperative period (mean time 28 days). All patients have been reevaluated in 2003 and it was diagnosed the thrombosis of two procedures, one of them with the recurrence of the ulcer who healed with conservative treatment. The authors consider this method as a very easy technique to perform, although rarely used, and a valid alternative in a highly selected group of patients.
