肠系膜上静脉血栓形成临床特点及预后相关因素分析

目的 探讨肠系膜上静脉血栓形成（SWVT）临床特征、诊治方法，研究预后相关因素。方法 回顾性分析华北理工大学附属医院2005~2015年40例肠系膜上静脉血栓形成患者临床资料。结果 主要症状有腹痛、腹胀、发热及呕吐等。40例患者中，29例行单纯抗凝治疗，11例行手术治疗，6例患者30天内死亡。与30天生存率相关的因素为肠切除和确诊前持续时间。结论 该疾病症状不典型，增强CT对诊断具有重要意义，抗凝为基础，保守治疗无效时手术治疗为主要治疗手段，肠切除和确诊前持续时间是影响SMVT 30天生存率相关因素。

Analysis of Clinical Features and Prognostic Factors of Superior Mesenteric Vein Thrombosis

Objective To investigate the clinical features, diagnosis and treatment of superior mesenteric vein thrombosis, and study the prognostic factors. Methods We analyzed clinical data of 40 patients with superior mesenteric vein thrombosis from 2005 to 2015 in the affiliated hospital of North China University of Science and Technology retrospectively. Results The main symptoms are abdominal pain, bloating, fever and vomiting. Of 40 patients, 29 were treated with anticoagulation alone, 11 received surgical treatment, and 6 died within 30 days. Factors associated with 30-day survival were bowel resection and duration of pre-diagnosis. Conclusion The symptoms of the disease are atypical. CT has great significance in diagnosis. Anticoagulation and operation are main treatments. The bowel resection and duration of pre-diagnosis are the influencing factors of 30-day survival rate of SMVT.
