Transplant renal artery stenosis (TRAS) is an uncommon complication following renal transplantation. Its usual clinical presentation includes worsening hypertension and/or renal function, without any evidence of graft rejection. Bifurcation renal artery stenosis of the transplanted renal artery is rarely encountered.
Percutaneous transluminal renal angioplasty (PTRA) with or without stenting is the procedure of choice to treat TRAS. We hereby describe a patient, who presented with impaired renal functions, four months following the renal transplantation. He underwent intravascular ultrasound-guided PTRA of the bifurcation lesion of TRAS. Superior renal artery had coronary drug-eluting stent implantation, while inferior renal artery and side branch of the superior renal artery had balloon angioplasty, alone. Post-intervention, the raised serum creatinine level decreased from 2.9 mg% to 1.7 mg%. The index case described the successful PTRA and stenting of the bifurcation lesion of TRAS, the technical results of which was optimized with the use of intravascular ultrasound.
移植肾动脉狭窄(TRAS)是肾移植后的一种罕见并发症。其常见临床表现为高血压和/或肾功能恶化,而无移植物排斥的任何证据。移植肾动脉的分叉部肾动脉狭窄很少见。
经皮腔内血管成形术(PTRA)联合或不联合支架置入术是治疗 TRAS 的首选方法。我们在此描述了一位患者,他在肾移植后四个月出现肾功能受损。他接受了血管内超声引导下的 TRAS 分叉病变的 PTRA。在 superior 肾动脉植入了冠状动脉药物洗脱支架,而 inferior 肾动脉和 superior 肾动脉的侧支则单独进行了球囊血管成形术。术后,升高的血清肌酐水平从 2.9mg%降至 1.7mg%。该病例描述了成功地对 TRAS 的分叉病变进行了 PTRA 和支架置入术,使用血管内超声优化了技术结果。
