Abstract
We report a case of nonocclusive mesenteric ischemia due to hypotensor drug abuse. This is the first case in Japan. A 52-year-old man who abused hypotensor drugs was admitted to our hospital with vomiting. He subsequently developed severe hypotension, aspiration pneumonia, and acute renal failure, but these symptoms resolved gradually after intensive treatment. On day 8, abdominal pain suddenly occurred. Computed tomography revealed ascites and ischemic changes in the small intestine and ascending colon. Emergency operation was performed to determine whether intestinal necrosis had occurred. Intraoperative examination revealed segmental, discrete necrosis from the lower part of the ileum to the right side of transverse colon ; however, the superior mesenteric artery was patent. The involved parts of the intestine were resected. The postoperative diagnosis was nonocclusive mesenteric ischemia, and the patient recovered uneventfully.
