摘要
目的探讨移植肾动脉狭窄的发病情况、相关因素、诊断与治疗方法。方法对10例同种异体肾移植术后出现血压升高及肾功能损害、经彩色多普勒超声筛查并经动脉造影证实为移植肾动脉狭窄患者的临床资料进行回顾性分析结果移植肾动脉狭窄的发病率为2.1%,其中7例有急性排斥反应病史。行球囊扩张术9例、支架置入术1例,除1例治疗无效外,其余患者术后高血压均有改善,血肌酐下降。单纯行球囊扩张术的9例病人中,2例出现再狭窄,行支架置入术后肾功能改善。结论移植肾动脉狭窄与术后急性排斥反应相关;彩色多普勒超声可用于筛查,移植肾动脉造影是诊断的金标准,介入治疗为有效治疗方法。
Objective To investigate the incidence and cause of transplant renal artery stenosis (TRAS) and explore its diagno-sis and management. Method A retrospective study was conducted in 10 TRAS cases confirmed by selective artery angiogra-phy between 2000 and 2001. Results Seven patients had a history of acute rejection episode, balloon angioplasty was per-formed in 9 patients, and stent implantation in 1 patient. Revascularization resulted in a decrease in arterial pressure and renal function improvement in all but 1 case. Restenosis occurred in 2 of the 9 patients receiving balloon angioplasty, but after stent implantation, their renal function was improved. Serious graft failure occurred in 1 case, resulting eventually in renal graft loss. Conclusions TRAS is related to episodes of acute rejection. Doppler ultrasonography is useful in screening of TRAS, the defi-nite diagnosis of which relies on artery angiography, and angioplasty constitutes an effective therapeutic modality.
