Abstract
|
|
|
|
Renal biopsy is an essential diagnostic tool for detecting acute and chronic kidney rejection as well as recurrent and de novo nephropathies in renal allograft recipients. However, a well-known complication of percutaneous renal biopsy is arteriovenous fistula (AVF). Most post-biopsy AVFs are asymptomatic and regress spontaneously but some AVFs result in hypertension, hematuria, and renal insufficiency. Whether post-biopsy AVF superimposed on transplant renal artery stenosis (TRAS) also regresses spontaneously is unknown. We present a case of acute renal insufficiency in a 51-year-old female renal allograft recipient with post-biopsy AVF and TRAS. Percutaneous angioplasty with stent implantation was performed for the TRAS and transcatheter arterial coil embolization therapy applied for AVF. The patient`s renal function returned to baseline levels and is currently being followed up for 6 months.
