Abstract: Objective To summarize the experience in treatment of acute superior mesenteric vein thrombosis（SMVT）and explore the better treatment approach. Methods A retrospective analysis were conducted in 36 patients with SMVT admitted to the Department of Vascular Surgery of the First Affiliated Hospital of Chongqing Medical University from January 2006 to December 2014. Results Of 36 cases, 5（13.9%）were dead, 31（31.6%）got improved, 7（19.4%）were re-operated. Conservative treatment was in 15 cases and 14 were cured. Surgical approach was in 15 cases and 12 discharged. Five cases got re- operated in 30 cases of conservative treatment and surgical procedure, in which 2 patients died of severe systemic infection with acute renal failure after reoperation because of abdominal pain and abdomi-nal distension after primary surgery, one case died of MODS within 48 hours after emergency necrolytic bowel resection. Interventional treatment was performed in 6 cases, 5 cases discharged, 2 cases were re- operated, and one case of SMA catheterized thrombolysis for 6 days died of severe intracranial hemorrhage. In addition, one case of DVT occurred 40 days after treatment, and did of pulmonary embolism, pulmonary infection and ARDS. Conclusion The preoperative diagnosis of SMVT is not easy. For patients with unexplained acute abdominal pain, this disease should be suspected in time. Early detection and treatment can improve the outcomes of this disease. Thrombolysis and thrombectomy can be used early in the course of the disease. Patients with signs of intestinal necrosis should undergo surgery in time and be treated with anticoagulation.
