摘　　要：目的 :探讨血管金属内支架在肝移植后血管并发症中的适应证和意义。方法 :回顾性研究了 8例使用血管金属内支架治疗肝移植后血管并发症的病例 ,并对术后病人情况进行了随访。结果 :5例下腔静脉狭窄 ,支架置入后均获得了成功 ,术后 2例 ( 2 /5 )分别存活了 2 2个月和 8个月 ,另 3例短期内死于其它原因 ;2例门静脉狭窄 ,1例 ( 1/2 )支架置入后存活了 3个月 ,1例术后 2周死亡 ;1例肝动脉狭窄支架置入患者术后短期内死亡。结论 :血管内支架放置术是一种处理肝移植后血管并发症的有效方法 ,它适用于肝移植后血管扭曲、旋转引起的血管狭窄 ,如肝移植术后早期发生的下腔静脉狭窄。血管内支架在治疗肝移植术后肝动脉狭窄并发症中应谨慎选择。其它原因所致的血管狭窄 。Objective:To determine the indication of stent placement for patients with vascular complication after liver transplantation.Methods:8 patients with vascular complications after liver transplantation were treated with stent endo prosthesis.Patients were followed up clinically.Results:All 5 patients with IVC complication were treated with stent placement successfully,2 of them survived for 22 and 8 months respectively, the remaining 3 cases died shortly after the procdure due to other causes.There were 2 cases with protal vein stenosis,one of them (1/2) had lived for 3 months after stent implantation,and another died in 2 weeks after the procedure.1 patient with hepatic arerty complication died in several days after the treatment.Conclusion:Endoprosthesis is an effective method for treating vascular complications occuring in patients who have undergone liver transplantation.It is indicated for treating vascular stenose caused by torsion or kinking,such as IVC stenosis in early postoperative period.It must be careful to select patients with artery complication to be treated with stent placement.The vascular complications by other causes should be treated by stent placement when PTA is not effective.
