a–d Selective left internal iliac artery angiography (IIA) in a patient suffering from pain and anemia after robotic prostatectomy shows the presence of a false aneurysm of the distal branch of the superior vescical artery (a). After superselective catheterization of the target vessel with a microcatheter (b), embolization is performed with Onyx 18. Filling of the pseudoaneurysmal sac, distal and proximal portion of the vescical artery is visible in c. IIA post-embolization angiography confirms effective occlusion of the target vessel
