Four patients with intrahepatic arterial aneurysms were treated with transcatheter embolization. Two patients had multiple aneurysms, and two had single aneurysms; in two the aneurysms were post-traumatic, and in the other two they were mycotic. Either Gelfoam or isobutyl-2-cyanocrylate was used to occlude the hepatic artery branches. It is concluded that transcatheter embolization is a safe and effective method for the management of these aneurysms and can be used as an alternative to surgery.

Twenty-seven symptomatic, benign postoperative strictures of the ureter or ureteropelvic junction were dilated with balloon or angiographic catheters in an attempt to definitively treat the strictures without surgery. Twenty-three dilatations were performed in antegrade fashion in conjunction with or subsequent to percutaneous nephrostomy, and four strictures were dilated in retrograde fashion per urethra. Thirteen of 27 strictures (48%) were successfully dilated. Certain strictures were more amenable to dilatation than others. In general, the potential for success in dilating ureteral strictures appears to be more dependent on the nature of the stricture than either its duration or the method of dilatation. Based on our initial experience, suggested techniques and guidelines for patient selection are offered.
