Abstract    Mesenteric ischemia represents an uncommon complication of acute port vein thrombosis. Though occurrence raises a lot in patients with underling diseases which requires a high level of suspicion to diagnose and therapy in a timely manner. The diagnosis of acute mesenteric ischemia and splanchnic vein thrombosis remains difficult due to the non-specific symptoms of those conditions. As diagnosis does continue to improve，treatment of acute mesenteric ischemia using medical management has become increasingly possible before it advances to the point at which surgical resection is required. For those failed in conservative treatment，the combination of interventional with surgical therapy should be actively operated.

Key words: acute port vein thrombosis, mesenteric ischemia, anticoagulation, thrombolysis

摘要： 急性门静脉血栓导致的肠缺血是相对少见的疾病，但是在有基础疾病病人中发生率明显升高，且预后较差，需要高度警惕并及时诊疗。由于急性肠系膜缺血和内脏静脉血栓形成的非特异性，临床诊断困难。但随着诊断水平的不断提高，明确诊断后及时药物治疗使得减少并发症已经变得越来越可能。对于保守治疗不能缓解的病人，应积极采用介入或开放手术相结合的治疗方法。
