Visceral artery aneurysms (VAA) can be treated by revascularization, ligation, or, most often, endovascular techniques depending on clinical presentation, hemodynamic status, and location. From 1975 to 2002 a total of 42 VAA in 34 patients were treated. The lesion involved the splenic artery (SA; 19), pancreaticoduodenal artery (PDA; 6), celiac trunk (CT;(More)
We report a type B aortic dissection treated with stenting of the descending thoracic aorta that subsequently developed an ischemic necrosis of the esophagus with a posterior mediastinum abscess. The surgical treatment consisted of an extra-anatomic bypass to revascularize the supra-aortic trunks and the distal abdominal aorta through a middle sternal(More)
Coexistence of aortic lesions and discitis is uncommon but potentially fatal if the diagnosis is not made promptly. We report the case of a 71-year-old patient with an infected prosthetic graft of the abdominal aorta impinging on the left ureter and accompanied with lumbar discitis. This triad has not been reported previously. Other unusual features in this(More)
BACKGROUND Radiofrequency segmental thermal ablation (RSTA) has become a commonly used technology for occlusion of incompetent great saphenous veins (GSVs). Midterm results and data on clinical parameters are still lacking. METHODS A prospective multicenteral trial monitored 295 RSTA-treated GSVs for 36 months. Clinical control visits included flow and(More)
This prospective and multicenter study shows the results at 1 year of radiofrequency-powered segmental thermal obliteration (RSTO) carried out with the ClosureFast procedure. The RSTO clinical and duplex ultrasound imaging results were evaluated at 3 days, 3 months, 6 months, and 1 year. All procedures were carried out on outpatients under tumescent local(More)
Carotid artery resection as part of the management of advanced head and neck cancers remains controversial. Since 1991, 30 patients have undergone resection of the carotid artery with immediate reconstruction using superficial femoral artery as replacement conduit. There was one stroke/death. Forty-three percent developed neck wound problems but no grafts(More)
Hand ischemia is a rare complication of angioaccess surgery for hemodialysis. Management usually requires ligation of the arteriovenous fistula (AVF). The purpose of this report is to describe our experience with the use of the distal revascularization interval-ligation (DRIL) technique for treatment of ischemia without ligation of the AVF. From January(More)
BACKGROUND Impaired vasomotor function has been suggested as playing a role in the pathophysiology of atherosclerosis and it may also affect the late patency of bypass grafts. We evaluated, in vitro, the influence of risk factors of atherosclerosis on saphenous vein endothelial function in patients with cardiovascular diseases. METHODS Forty-five(More)
OBJECTIVE To elucidate the organization of the tissue angiotensin system, we investigated the expression and cellular localization of angiotensin system components and cathepsins D and G, potentially involved in intraparietal angiotensin II formation and atheroma. METHODS Total RNA was extracted from atheroma plaque, fatty streaks and macroscopically(More)
