Six patients with mesenteric vein thrombosis (MVT) after devasculation for portal hypertension were treated by intestinal resection. Two patients had recurrence of thrombosis after the initial operations. Among 6 patients 2 survived and 4 (66.7%) died. MVT is an underappreciated, patentially lethal complication after revasculation. Three pathogenic factors after the operation may lead to thrombus formation of the portal vein, portal congestion, hypercoaguble state, and extensive ligation of portal branches. The complication commonly occurs in the recent period after devasculation. It is a characteristic manifestation of MVT that abdominal pain is out of proportion to physical findings. The most effective method is resection of infarcted bowel with sufficient length of normal bowel and its mesentery. In order to avoid a recurrence of thrombosis, postoperative anticoagulation treatment should be given.
6例因门静脉高压症行去血管化术后发生肠系膜静脉血栓形成（MVT）的患者接受了肠切除术治疗。2例患者在初次手术后血栓复发。6例患者中2例存活，4例（66.7%）死亡。MVT是去血管化术后一种未得到充分认识的、潜在致命的并发症。术后三个致病因素可能导致门静脉血栓形成、门静脉淤血、高凝状态以及门静脉分支的广泛结扎。该并发症通常发生在去血管化术后近期。腹痛与体格检查结果不成比例是MVT的特征性表现。最有效的方法是切除梗死肠段并带有足够长度的正常肠段及其系膜。为避免血栓复发，术后应给予抗凝治疗。
