极高的发病率和死亡率与急性肠系膜上动脉闭塞有关,这种闭塞是由延误诊断和缺乏为恢复和维持局部血流的合适方法所引起。对栓塞的具有动脉粥样硬化的动脉施行急症血管再建手术成功率很低,而急症取栓子效果稍好。等到手术探查时,常常是小肠已经坏死。Boley 等提出了一种积极的放射科与外科结合早期改善肠系膜缺血的方法。对选择性急性肠系膜缺血病人,确诊后使用介入性操作向动脉内灌注血管扩张药提高了患者存活率。Katzen 和Breda 描 Extreme morbidity and mortality are associated with acute superior mesenteric artery occlusion, which is caused by a delay in diagnosis and lack of a suitable method for recovery and maintenance of local blood flow. Successful embolization of atherosclerotic arteries with acute revascularization has a very low success rate, whereas emergency embolization is slightly better. Wait until the surgical exploration, often the small intestine has been necrosis. Boley et al proposed a positive combination of radiology and surgery early means of improving mesenteric ischemia. For patients with selective acute mesenteric ischemia, interventional arterial infusion of vasodilators improves patient survival after diagnosis. Katzen and Breda sketches
