目的探讨肾移植急性动脉狭窄的影像学表现及介入治疗的价值。资料与方法 15例肾移植动脉狭窄患者均有高血压和肾功能不良。均采用股动脉插管造影,明确诊断后行球囊扩张(PTA)和/或置入支架。结果15例中,6例行PTA治疗,9例行支架置入,操作全部成功。6例PTA治疗者中2例术后1个月出现再狭窄,行支架置入;9例支架置入者1年内有1例出现再狭窄。15例肾移植动脉狭窄患者介入治疗后均有血压下降和肾功能改善。结论肾移植动脉狭窄分为受体动脉狭窄、供体肾动脉狭窄和吻合口狭窄。血管造影是诊断肾移植动脉狭窄的金指标。介入治疗应作为肾移植急性动脉狭窄的首选疗法。
Objective To investigate the imaging findings of acute renal artery stenosis and the value of interventional therapy. Materials and Methods All 15 patients with renal artery stenosis had hypertension and renal dysfunction. All femoral artery catheterization angiography, a clear diagnosis of balloon dilation (PTA) and / or stent placement. Results Among the 15 cases, 6 cases were treated with PTA and 9 cases were treated with stents. The operation was successful. Two of 6 patients with PTA had restenosis at 1 month after operation, and were treated with stents. One of 9 stents received restenosis within one year. 15 patients with renal artery stenosis patients after interventional therapy have decreased blood pressure and renal function improved. Conclusion Renal transplantation stenosis is divided into recipient artery stenosis, donor renal artery stenosis and anastomotic stenosis. Angiography is a gold index for the diagnosis of arterial stenosis in renal transplantation. Interventional therapy should be used as the preferred treatment of acute renal artery stenosis.
