Venous 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 gr...

A síndrome febril indeterminada no idoso coloca sempre alguma dificuldade diagnóstica. A endocardite infecciosa, pela relativa raridade e pela atipia das suas manifestações é muitas vezes esquecida neste grupo etário, onde outras causas, nomeadamente neoplásicas, são primeiramente consideradas. Os autores apresentam um caso clínico de uma doente idosa com endocardite infecciosa subaguda mitral e tricuspide, cujo diagnóstico foi estabelecido apenas após embolização periférica. Para além de fenómenos embólicos múltiplos, esta doente teve ainda como complicação um aneurisma micótico da artéria femural esquerda a que foi operada.

OBJECTIVE: 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 th...
