门静脉系统抗凝预防断流术后门静脉系血栓形成

Portal anticoagulation in preventing thrombosis after portaazygous devascularization for portal hypertension

目的 探讨门静脉高压症断流术后门静脉系血栓形成的预防方法。方法 将 71例肝硬化门静脉高压症患者分为 2组 :A组 36例在断流术中经脾静脉分支插入抗凝管 ,术后行门静脉系抗凝治疗 ;B组 35例断流术后未行门静脉系抗凝治疗。结果 术后 3个月内彩超检查 ,A组门静脉系均未见血栓形成 ,B组门静脉系血栓形成 13例 (37 14% )。结论 门静脉系统抗凝治疗是预防门静脉高压症断流术后门静脉系血栓形成的有效方法。

Objective To study the prevention method for thrombosis after porta azygous devascularization for portal hypertension. Methods 71 patients with portal hypertension due to cirrhosis were divided into group A (36 patients) and group B (35 patients).In group A, a anticoagulation tube was in serted via splenic vein branch during shunt and anticoaguation therapy was given after operation. Results All the patients received color Doppler examination 3 months after operation.No thrombosis occurred in the group A and thrombosis occurred in 13 patients (37.14%) in the group B. Conclusion Potal anticoagulation therapy is the effective in preventing portal thrombosis after porta azygous devascularization for portal hypertension.
