AimTo discuss and evaluate the diagnosis, differenis surgical techniques and prognosis of superior mesenteric artery occlusion(SMAO). Methods38 cases of acute superior mesenteric artery occlusion were treated with individualized surgical methods.Acute abdominal pain was the important clinical presentation.All the patients were diagnosed as SMAO by computed tomography arteriography (CTA) before treatment.According to individual condition, 38 patients accepted revascularizations including transcatheterizing thrombolysis, thromboembolectomy, ballon dilatation and stent implant, autologous vein or vascular prosthesis bypass/transplantation and resection of necrotic bowel respectively.ResultsIncision healed by first intention in all patients were followed up 6 months.The circulation of the intestine returned to normal in 30 patients by reexamination of color doppler ultrasonography.4 cases developed short-gut syndrome after operation and 3 cases died, and 2 cases developed intestinal fistula with death of 1 case; Severe infection and multiple organ failure was found in 3 patients and 2 cases died; And there were 6 patients with reperfusion injury, and 6 patients with deterioration of the primary affection and 2 of them died of heart failure.The overall incidence of postoperative complication was 55.2% and the overall mortality rate was 21.1%.ConclusionEarly recognization by appropriate examination and early treatment with individualized surgical methods will improve the prognosis of SMAO.
