Case Report : Delayed Hemorrhage from an Accessory Internal Pudendal Artery Pseudoaneurysm after Robotic Radical Prostatectomy: Successful Management with CT Angiography and Embolization

Abstract

We present the first report of a pseudoaneurysm of an accessory internal pudendal artery after transperitoneal robotic radical prostatectomy. The vesicourethral anastomosis was performed using two continuous 3-0 Monocryl sutures tied at the six o'clock position. As the anastomotic suture was placed at 11 o'clock, lateral to the dorsal venous complex, there was a small amount of pulsatile bleeding that ceased when the suture was completed and tied. The lesion presented as hematuria beginning on the fourth day. On the 14^th day, the pseudoaneurysm was diagnosed by CT angiography and treated by embolization with eight 3-mm/30-mm micro coils after superselective catheterization. There were no complications or further hematuria.
