- Lesões Traumáticas Iatrogénicas das Veias Femorais no Decurso da Cirurgia de VarizesPublication . Albino, JP; Meireles, N; Martins, J; Silva Castro, J; Duarte, J; Gonçalves, A; Amaral, C; Bettencourt, V; Gonçalves, D; Mota Capitão, L; Carvalho, STraumatic lesions of the femoral veins during varicose veins surgery are very uncommon and they raise several therapeutic difficulties. They occur in 1/1000 cases of varicose veins operated. The authors describe four cases of lesions of this type that were seen and treated for the last six years, probably because there was an increase in the number of varicose veins operated on in the Lisbon area. The authors discuss the surgical options and they concluded that these complications can be minimized with good anatomical and surgical skills, specially of the saphenous-femoral and saphenous-popliteal junctions.
- Procedimentos Endovasculares AórticosPublication . Alves, G; Vasconcelos, L; Gonçalves, F; Rodrigues, H; Valentim, H; Silva Castro, J; Ferreira, E; Albuquerque e Castro, J; Mota Capitão, LOs autores apresentam uma análise retrospectiva de todos os procedimentos endovasculares aórticos realizados no Serviço, até Novembro de 2009. A série inclui 302 doentes, dos quais 246 correspondem ao tratamento electivo de aneurismas da aorta abdominal, 33 ao tratamento de aneurismas da aorta abdominal em contexto de urgência e 23 a procedimentos endovasculares da aorta torácica. O objectivo da análise visa descrever as características epidemiológicas, incluindo patologia associada, assim como mortalidade major e mortalidade aos 30 dias de pós-operatório.
- Síndrome de Churg-Strauss, Aneurismas Femorais Venosos e Tromboembolismo PulmonarPublication . Meireles, N; Ferreira, E; Silva Castro, J; Amaral, C; Sobrinho, G; Franca, T; Albino, JP; Carvalho, CSOBJECTIVE: Venous aneurysms of the lower limbs are rare. When they involve the deep venous system, they can be associated with deep venous thrombosis and pulmonary embolism. The authors report the case of a 63-year-old women evaluated by duplex imaging and venography, in the context of a pulmonary embolism, and detected bilateral large aneurysms of the femoral veins (5 cm in the right femoral vein and 4 cm in the left femoral vein). The aneurysms were located at the bifurcation of the common femoral vein with the superficial and profound veins. METHOD: The right aneurysm was partially thrombosed. The patient was asymptomatic in the lower-limb extremities. After a period of anticoagulation, the authors proceeded to surgically excise the right aneurysm and replaced the venous system using a polytetrafluoroethylene (PTFE) graft with the construction of an a-v fistula. RESULT: The patient had no complications in the postoperative period and her 8-month follow-up examination revealed no symptoms, not even leg edema. The duplex scan showed patency of the graft. She continued with oral anticoagulation. The histologic examination revealed an eosinophilic inflammatory reaction of the vein wall, compatible with the diagnosis of Churg-Strauss syndrome. CONCLUSION: The authors conclude that they have probably described the first case in the international literature of a venous aneurysm with a Churg-Strauss syndrome and pulmonary embolism.
- Tumores do Corpo Carotídeo. Experiência de um Serviço no Diagnóstico e Tratamento nos Últimos 10 AnosPublication . Valentim, H; Gonçalves, H; Vasconcelos, L; Garcia, AC; Silva Castro, J; Ferreira, E; Albuquerque e Castro, J; Mota Capitão, LINTRODUCTION: Carotid body tumours (CBT) are neoplasms that develop from paragangionic cells of this structure. They are rare, with an estimated incidence of 1:30000 and can be associated with other neuro-endocrine neoplasia. The authors report their experience in the management of the disease, in the last 10 years. MATERIAL AND METHODS: Eight patients (with eight tumours) were treated, all submitted to tumour resection. 75% were female and the mean age was 56 years. We report a 12,5% incidence of neurological sequelae from surgery, and no mortality. In the follow-up (which varied between 1 and 10 years), no local or contralateral recurrence or metastasis were registered. Also, we did not found family cases of this disease. CONCLUSIONS: The authors noticed an unusually high proportion of female patients. The tumour resection was curative in all patients, with a rate of neurological complications inferior to that reported in other published series. These neurological sequelae were reported in patients with large tumours, thus reinforcing the outmost importance of an early diagnosis. Pre-operative selective embolization of these tumours can be helpful in the resection of large tumours, allowing a potential reduction in neurological complications.
