Cerebral embolization in asymptomatic versus symptomatic patients after carotid stenting.

Background: Previous studies have investigated the development of new ischemic brain lesions on diffusion-weighted magnetic resonance imaging (DW-MRI) after carotid artery stenting (CAS). The rate of ischemic brain injury after CAS for asymptomatic stenosis has not been extensively studied but is presumed to be less likely than in symptomatic patients. This study assessed the occurrence of cerebral embolization after CAS for asymptomatic vs symptomatic carotid stenosis.

Delayed reconstruction of the superior mesenteric vein with autogenous femoral vein.

A 38-year-old man underwent ligation of the superior mesenteric vein due to traumatic disruption. He developed severe bowel edema with large fluid losses through the open abdominal incision. On postoperative day 9, a superior mesenteric vein bypass was performed with autogenous femoral vein, and this resulted in prompt resolution of the bowel edema and allowed abdominal wound closure.
