Abstract:
An 81-year-old woman developed abdominal pain after off-pump CABG (OPCAB) for unstable angina pectoris. X-ray film and CT scan showed paralytic ileus the day after surgery. A presumptive diagnosis of mesenteric ischemia was made and exploratory laparotomy was performed. During surgery, however, there was no sign of mesenteric ischemia. The patient still complained of abdominal pain after the laparotomy, so selective angiography of the mesenteric artery was performed. The angiography showed remarkable vasospasm of the superior mesenteric artery (SMA) and diagnosis of nonocclusive mesenteric ischemia (NOMI) was made and continuous intra-arterial perfusion of papaverine into the SMA was started. Control angiography during papaverine perfusion showed a clear reduction of vasospasm. Thereafter, the patient developed diffuse peritonitis due to intestinal gangrene on postoperative day 12 and was compelled to undergo extensive resection of the intestine and sigmoidectomy. She could not be weaned from the ventilator due to respiratory insufficiency and died of multiple organ failure about 5 months after OPCAB. NOMI can develop even in OPCAB, in which cardiopulmonary bypass is not required. Therefore maintenance of stable hemodynamics intraoperatively, careful management of the postoperative state and early diagnosis and therapy are essential to prevent NOMI.
