Percutaneous transcatheter embolization of deep visceral pseudoaneurysms]

The authors present their experience with the percutaneous embolization of 13 splanchnic aneurysms and pseudoaneurysms (2 pseudoaneurysms of gastroduodenal artery, 3 of the hepatic artery, 7 renal pseudoaneurysms, 1 aneurysm of the splenic artery). In 9 of 13 cases the lesions were iatrogenic. Embolizing devices and techniques are described. Percutaneous embolization was successful in 12 of 13 cases, and useless in 1 case of renal pseudoaneurysm. In the 12 successfully treated cases the lesions were still occluded in the follow-up period. Transcatheter percutaneous embolization is the elective treatment in splanchnic aneurysms and pseudoaneurysms; surgery must be performed only when embolization fails.
