移植肾动脉栓塞在移植肾失功并发症治疗中的应用

目的探讨移植肾动脉栓塞在移植肾失功并发症治疗中的应用。方法2006年5月至8月对沈阳军区总医院介入治疗中心6例移植肾失功患者行移植肾动脉栓塞,观察患者临床症状和移植肾形态、血流的变化。结果血尿患者栓塞后3d内血尿均消失,血压用药物维持在正常范围。1周后复查彩色多普勒,4例移植肾血流完全消失,2例呈点片状血流分布;3个月后复查栓塞后移植肾均未见血流,移植肾明显萎缩。结论移植肾动脉栓塞用于移植肾失功并发症的处理具有疗效确切、安全等优点,尤其对于体质差的患者,可避免移植肾切除手术带来的风险。

Application of embolism of renal artery to treatment of complications associated with non-functioning renal allografts

Objective To explore the treatment of complications associated with non-functioning renal allografts using embolism of renal artery.Methods Six patients with non-functioning renal allografts were treated with renal artery embolism,morphous,blood flow of allografts and symptoms were observed.Results Hematuria disappeared in 3 days after embolism;blood pressure levels controlled by drugs were in a normal region.Using color Doppler sonography,we found no blood flow in 4 cases,discontinuous blood flow in 2 cases.Blood flow disappeared in all 6 allografts 3 months later,and the allografts had atrophied.Conclusion Embolism of renal artery may be an effective and safe method for the treatment of complications associated with non-functioning renal allografts,especially for some severe patients;it could avoid the risks of operation.
