The Surgical Outcome of Patients with Superior Mesenteric Arterial Occlusion

Abstract

The surgical outcome of patients with superior mesenteric arterial occlusion (SMAO) was investigated by comparing patients with and without vascular treatments. In total, 11 patients who underwent surgical treatment for SMAO were evaluated. Six patients underwent angioplastic surgery (APS group), and five patients did not (No APS group). There were no significant differences between the two groups in the ASA-PS, APACHEII, E-PASS, and the Glasgow prognostic score. The nutritional index was significantly lower in the No APS group than in the APS group. The time from onset to operation was shorter in the APS group than in the No APS group. The length of the resected intestine was shorter and the length of the remnant intestine was longer in the APS group than in the No APS group. The operative mortality was 18.2% (2 cases) ; they died of multiple organ failure with severe heart disease. The survival rate of patients who underwent surgical treatment for SMAO was 81.8% ; the survival rate was especially high with angioplastic surgery for cases of occlusion around the origin of the superior mesenteric artery.
