移植肾动脉狭窄的介入治疗

Interventional treatment of transplanted renal artery stenosis

目的探讨移植肾动脉狭窄介入治疗的方法和疗效。方法9例移植肾动脉狭窄的病人,经股动脉入路行狭窄段的导管球囊扩张和内支架植入术。结果9例移植肾动脉的患者均成功完成球囊扩张术,其中3例行内支架植入术,治疗后一周7例血压基本恢复正常,2例靠药物维持,所有患者的肌酐术后均明显下降。结论导管球囊扩张和内支架植入术对治疗移植肾动脉狭窄有较高的临床应用价值。

Objective To evaluate the clinical application of percutaneous transluminal renal artery angioplasty(PTRA)in the treatmemt of transplanted renal artery stenosis.Methods Nine patients with transplanted renal artery stenosis were treated by PTRA with balloon catheter through the famoral artery .Metal stent was placed in 3 patients out of 9.Result Technical success was obtained in all procedures. In 7 patients normal blood pressure was restored and serum creatinine renarkalby decreased.But anti-hypertention drugs were still needed in rest 2 patiests.Conclusion PTRA and stent implantation are useful and valuable method in the treatment of transplanted renal artery stenosis.
