Revision Surgery for Venous Graft Stenosis of SMA Bypass.

Abstract

A 67-year-old male with postprandial abdominal pain for 4 months obtained medical attention for severe pain. He was diagnosed with small intestinal necrosis, secondary to chronic mesenteric ischemia by CT scan. We performed the surgery including a partial resection of the small intestine and left external iliac artery to the superior mesenteric artery bypass using saphenous vein graft. His symptoms improved after surgery. However, 5 months later, abdominal pain appeared after eating. A CT scan identified graft stenosis, leading to a revascularization. A synthetic vessel was used to perform the re-bypass surgery. Postoperatively, the patient's abdominal pain improved.
