[Percutaneous transcatheter therapy of visceral pseudoaneurysms].
BACKGROUND
The purpose of this work is to show the effectiveness of percutaneous embolization therapy in the treatment of visceral arterial pseudoaneurysms and to propose the method as a valid alternative to surgery.


METHODS
Twenty-eight patients with visceral artery pseudoaneurysms were treated: 10 of them were hepatic; 9 renal; 7 duodenal-pancreatic; 1 splenic and 1 of the celiac trunk. Materials employed were: Gianturco metallic coils, Spongostan and Poli-Vinyl-Alcohol.


RESULTS
Immediate success was obtained in all cases; recurrences occurred in 5 patients (18%) and they have all been successfully retreated with percutaneous method; complications occurred in 3 patients (10%) and they were all directly related to the pre-existing pathology and not to the percutaneous treatment.


CONCLUSIONS
To obtain the best results from embolization, it is necessary to respect some conditions regarding the correct choice of embolic materials, the superselective catheterization of the injured artery and the low injection pressure of the contrast medium in order to avoid rupturing the thin pseudoaneurysmatic wall. The advantages of the percutaneous treatment are: less trauma, local anesthesia, reduction of the time between diagnosis and therapy, reduction of hospitalization stay and limitation of parenchymal destruction, Complications are relatively not frequent and in no cases the percutaneous therapy compromised the surgical intervention when it became necessary.
