Transcatheter ablation of an iatrogenic renal artery pseudoaneurysm with absolute alcohol: A rare case report

Abstract

A 25 year old male was admitted with features of life threatening renal haemorrhage after undergoing open nephrolithotomy for a staghorn calculus of the right kidney. CECT abdomen and selective renal angiography revealed a 2.5 × 3.0 cm pseudoaneurysm arising from the lower segmental branch of right renal artery, leaking into retroperitoneal space. After an initial failed attempt of transcatheter embolization with N-butyl cyanoacrylate (NBCA) and 10% lipiodol mixture, the pseudoaneurysm was successfully ablated with absolute alcohol. Our case demonstrates that absolute alcohol ablation is a safe and effective modality for controlling haemorrhage from an iatrogenic renal artery pseudoaneurysm.

Percutaneous transcatheter super-selective renal arterial embolization with N-butyl cyanoacrylate for iatrogenic renal hemorrhage

“… 1 , 2 A variety of embolic agents have been used in SRAE for renal hemorrhage, including gelatin sponge pieces, polyvinyl alcohol particles, microcoils, and liquid glue, all with their own various pros and cons. 4 , 5 , 6 , 7 , 8 A consensus on which embolic agent should be used is lacking. Thus, the choice of embolic agent is usually made on a case-by-case basis, depending on various factors such as vascular anatomy and pathology, coagulation status of the patient, material availability, and personal preference of the interventional radiologist performing the procedure.…”
