Treatment of a complicated penetrating ulcer of the descending thoracic aorta using a scalloped stent graft.

We show the use of a proximal scalloped stent graft for an pseudoaneurysm of the descending thoracic aorta to avoid occlusion of the left subclavian artery. A 63-year-old man with sudden onset dysphonia was diagnosed with left vocal fold paralysis and the presence of a lung mass. A computed tomography scan revealed saccular dilatation of the aortic arch (proximal neck: <10 mm) with suggestive images of a penetrating ulcer and degenerative pseudoaneurysm.

[Lymphoscintigraphy study of oedema after femoropopliteal segment surgery].

Introduction: Post-surgical oedema of the femoropopliteal segment is a frequent complication, unrelated to the severity of the previous symptoms or changes in subsequent distal arterial pressure. The aim of the study is to assess whether the oedema present in femoropopliteal bypass patients is of lymphatic origin, and the possible influence of the prosthesis and the type of intervention used.

Patients And Methods: An analytical, observational and case-control study of 30 patients who had a femoropopliteal bypass.

[Prevalence of renal artery stenosis in patients with critical limb ischemia].

Background And Objective: Our purpose was to evaluate the prevalence of renal artery stenosis in patients with critical limb ischemia and to study any clinical or laboratory indicator that could predict this association.

Patients And Method: One hundred consecutive patients with critical limb ischemia evaluated by angiogram were included in the study from January to July 2003. Cardiovascular risk factors and renal function were analyzed.
