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
