Abstract: Mesenteric vascular occlusion（MVO）is a series of syndromes caused by mesenteric artery embolism or thrombosis，mesenteric vein thrombosis leading to acute intestinal ischemia（AMI），which can lead to intestinal necrosis or even death. Pregnancy complicated with MVO is a rare surgical acute abdomen with high misdiagnosis and mortality rate due to atypical early symptoms and lack of specific tests. This article elaborates on the etiology，epidemiology，clinical manifestations，risk factors，diagnosis and treatment of the disease，aiming to improve the understanding of clinicians about this disease，assist the early diagnosis，and thus improve the survival rate and prognosis.

Key words: pregnancy, mesenteric vascular occlusion , mesenteric artery embolism, mesenteric arterial thrombosis, mesenteric venous thrombosis

摘要： 肠系膜血管栓塞（mesenteric vascular occlusion，MVO）是由于肠系膜动脉栓塞或血栓形成、肠系膜静脉血栓形成导致急性肠系膜缺血引起的一系列综合征，严重者可导致肠坏死甚至死亡。妊娠合并MVO是一种罕见的外科急腹症，因早期症状不典型和无特异性检查，误诊率和病死率都较高。文章对妊娠合并MVO的病因及流行病学、临床表现与危险因素、诊断和治疗等方面进行阐述，旨在提高临床医生对该病的认识，协助早期诊断，进而提高生存率，改善预后。
