INTRODUCTION

Renal biopsy of the allograft is important to evaluate renal dysfunction (1). Rare complications like pseudoaneurysm (PA) can develop and could lead to life-threatening bleeding (2, 3). It can be safely and effectively managed by endovascular embolization yielding good renal function in the long term follow-up (4, 5). We describe a PA of a kidney transplant (KTX) associated with arteriovenous fistula (AVF) at the site of a core needle percutaneous biopsy (CNPB).
