肾移植术后移植肾假性动脉瘤临床分析

目的:探讨肾移植术后移植肾假性动脉瘤的诊断与治疗方法。方法:对4例肾移植术后移植肾假性动脉瘤患者的临床资料、诊断及治疗情况进行回顾性分析。结果:本病临床表现不典型,发热2例,移植肾区疼痛3例,尿量减少2例,血肌酐升高2例。4例均行移植肾彩色多普勒超声检查,3例行血管造影确诊为移植肾假性动脉瘤。治疗上,2例行移植肾加动脉瘤切除术,其中1例同时行髂外动脉人工血管端端吻合;1例采用带膜支架髂外动脉置入治疗;1例未作特殊处理,仅定期随访观察。结论:彩色多普勒超声检查对本病的诊断较具价值,血管造影可确诊。移植肾加动脉瘤切除术是常用的方法,带膜支架置入治疗移植肾假性动脉瘤是一种微创、有效、安全的治疗方法。

Clinical study of renal transplant pseudoaneurysm

Objective:To present our experience in the management of renal transplant pseudoaneurysm.Methods:The clinical data of 4 cases of patients with renal transplant pseudoaneurysm were retrospectively analyzed.Results: No typical symptom was noted in this diease.Color Doppler flow(CDF) examinations were performed in 4 cases and 3 cases presented cystic mass around the renal vessel.Angiography was conducted in 3 cases and all shew renal transplant pseudoaneurysm The remaining one case's diagosis was confirmed by surgical detection.Two patients underwent nephrectomy: one of which received artificial vessel aoastomose of external iliac.Another one received stent-graft placement across the external iliac artery.The remaining one case is under watchful waitingS.Conclusions:Renal transplant pseudoaneurysm can be diagnosed by color Doppler flow.But the correct diagnosis of pseudoaneurysm was made after angiography.Surgical treatment was effective.Radiologic interventional procedure was a safe,effective,minimally invasive alternative surgical technique for the renal transplant pseudoaneurysm.
