Abstract | Transplant renal artery stenosis (TRAS) is a common vascular complication after kidney transplantation, leading to worsening or refractory hypertension, deterioration in renal function, and possible cause of graft loss. Early diagnosis and an appropriate treatment are crucial for organ preservation. Endovascular treatment, including percutaneous transluminal angioplasty and stent implantation, is considered the first-line therapy for TRAS. Here we report the case of a 69-year-old woman with end-stage renal disease for chronic kidney disease not biopsy proven, who underwent a kidney transplant from expanded criteria donors on December 2018. Postoperative course was characterized by delayed graft function. Doppler ultrasonography (US) showed an increase of peak systolic velocity at the origin of the renal artery, and parvus-tardus waveform in periferic graft arteries and an abdominal computed tomography scan confirmed a stenosis at the origin of the main renal artery (TRAS). The patient underwent a percutaneous transluminal angioplasty. It was not possible to place a stent at the particular location of the stenosis at the anastomosis. Despite the improvement of the graft's perfusion, monitored with Doppler US, the patient showed a very poor improvement in renal function and remained on hemodialysis for months. A percutaneous needle biopsy reported a normal renal parenchyma and excluded acute rejection. During this period, the patient received immunosuppressive therapy. About 6 months after the transplant, the patient had an unexpected and slow renal function recovery until she was weaned completely from hemodialysis. |
