Intestinal Perfusion Studies Using 133Xe During Correction of Mesenteric Vascular Insufficiency: Case Report

Radioxenon clearance studies of bowel perfusion were obtained during laparotomy in a patient with mesenteric vascular insufficiency. These studies were obtained both before and immediately after bypass of the occluded superior mesenteric artery. Although clearance rates improved after the bypass surgery, normal rates were not achieved.
