Suprarenal stent perforation after endovascular abdominal aortic aneurysm repair.

A 66-year-old man with an abdominal aortic aneurysm previously repaired with an endovascular stent graft presented to our facility with worsening midabdominal and back pain. Previous postoperative surveillance computed tomography scans were unremarkable, showing excellent stent-wall apposition and a shrinking aneurysm sac; however, imaging done on his arrival identified a contained rupture at the level of the celiac artery containing a perforating suprarenal stent. We repaired this rupture with a surgeon-modified fenestrated stent graft.

Duplex scan for deep vein thrombosis--defining who needs an examination of the contralateral asymptomatic leg.

Objectives: Determine the prevalence and clinical significance of deep venous thrombosis (DVT) in the asymptomatic contralateral extremity of patients referred to the vascular laboratory with unilateral symptoms and DVT confirmed by duplex scan.

Method: From December 2003 to October 2006, a total of 4813 patients were referred to our vascular laboratory for unilateral venous duplex scans. We prospectively studied 239 patients who were found to have acute DVT and had unilateral symptoms.
