移植肾动脉狭窄的介入治疗

Percutaneous transluminal angioplasty of arterial stenosis following renal transplantation

目的 :评价经皮血管腔内成形术 (PTA)对移植肾动脉狭窄 (RTAS)的治疗作用。方法 :对 9例移植肾动脉狭窄的患者行PTA ,患者的血管狭窄位于外科手术血管吻合处或吻合远端的移植肾动脉上。 8例采用经股动脉入路 ,1例采用经肱动脉入路。疗效以临床随访、肾功能检验、超声检测为评价。结果 :9例移植肾动脉狭窄的患者成功地实施了PTA ,2例患者置入支架 ,所有病例均痊愈。结论

Objective:To assess the value of percutaneous transluminal angioplasty (PTA) for the treatment of renal transplant arterial stenosis(RTAS).Methods:PTA was performed in 9 patients with RTAS,which was located in the renal arterial anastomosis or renal transplanted artery distal to the anastomosis.The procedure was done with femoral arterial access in 8 cases and brachial access in one.The curative effect was assessed by clinical follow up,renal laboratory test and ultrasound. Results:Angioplasty was successfully performed in 8 paitents with RTAS,and additional stenting performed in 2 patients.All patients were well discharged.Conclusion:PTA is an effective method for treatment of RTAS.It may be regarded as the first choice method for the treatment of RTAS.
