肝移植术后管腔重建相关并发症的介入治疗

目的：探讨介入技术治疗肝移植术后血管和胆管管腔重建相关性并发症的可行性。方法：肝移植术后共有16例相关并发症患者接受介入治疗，其中肝动脉狭窄4例，肝动脉血栓形成2例，门静脉狭窄并血栓形成1例，胆管吻合口狭窄9例。肝动脉狭窄行球囊扩张（PTA）或内支架治疗，肝动脉血栓形成行导管接触性溶栓治疗，门静脉狭窄并血栓形成行溶栓、支架置入及分流道栓塞治疗，胆管吻合口狭窄行PTA或支架置入治疗。结果：16例患者均获技术成功，治疗均有效，有效率为100%。4例肝动脉狭窄1例单纯PTA有效，3例行支架置入术后有效，血流恢复。2例肝动脉血栓形成术后血栓消失，血流恢复通畅。1例门静脉并发症治疗后血流恢复，灌注增加。9例胆管吻合口狭窄2例行PTA有效，7例置入支架后有效。随访0.5～17个月无复发，5例死于原发病进展或系统并发症，与该并发症或介入治疗无关。结论：介入技术成功率高、并发症少，是治疗肝移植管腔重建相关并发症的有效方法。

Interventional treatment for lumen reconstruction correlated complications after liver transplantation

Objective: To explore the feasibility of interventional treatment for vessel and bile duct reconstruction correlated complications after liver transplantation.Methods: Interventional procedures were carried out in 16 cases of complications after liver transplantation including 4 cases of hepatic artery stenosis,2 cases of hepatic artery thrombosis,one case of portal vein stenosis combined thrombosis and blood shunt,9 cases of bile duct stenosis.PTA or stent placement were performed in patients with stenosti...
