Abstract
Background: Renal arteriovenous malformation (AVM) in Hereditary Hemorrhagic Telangiectasia (HHT) is uncommon and only few cases have been described, mainly with surgical management because of uncontrolled hematuria.
Case presentation: We managed a 70-year-old patient with HHT who presented with hematuria and left flank pain. Computed Tomography and ultrasound showed left renal AVM of 18 mm with clotting in the urinary tract. An external ureteral catheter was placed during 3 days to allow rinsing and facilitate elimination of clots. Given the patient's hemodynamic stability, a non-surgical management was chosen. Treatment of the AVM was performed by trans-arterial embolization using micro-coils and ethylene-vinyl alcohol copolymer.
Conclusions: Our case study shows a conservative management by embolization of ruptured left renal AVM revealed by hematuria in a 70-year-old patient with HHT.
