A new therapeutic approach to congenital pelvic arteriovenous malformations.

Background: Internal iliac arteriovenous malformations (AVM) are difficult to treat. Arterial embolization is chosen in most cases but the angio-architecture of these arteriovenous shunts can provide an explanation for the several reported failures. We report the long-term results of peroperative intravenous embolization.

Resveratrol inhibits vascular smooth muscle cell proliferation and induces apoptosis.

Objective: In France, despite a high intake of dietary cholesterol and saturated fat, the cardiovascular death rate is one of the lowest among developed countries. This "French paradox" has been postulated to be related to the high red wine intake in France. The aim of this study was to determine the effects of resveratrol, a major polyphenol component of red wine, on vascular smooth muscle cell (SMC) proliferation in vitro.

Iliac artery rupture during balloon dilatation: what treatment?

Intraoperative and postoperative arterial ruptures associated with 657 iliac artery balloon dilatation procedures in our department from 1981 to 2000 were prospectively collected and retrospectively analyzed. Our results showed that failure to exercise basic safety principles and the presence of heavily calcified plaque are the major predictors of iliac artery rupture during balloon dilatation. If rupture is contained, surveillance alone is unreliable.

Endograft fabric disintegration simulating a type II endoleak.

Purpose: To report a case of endograft disintegration misinterpreted as a type II endoleak.

Case Report: An 86-year-old man underwent successful Vanguard stent-graft implantation for a 49-mm abdominal aortic aneurysm. At 1 month, a distal type I endoleak was repaired, but another endoleak thought to arise from the lumbar or inferior mesenteric arteries remained.
