    Abstract:
    OBJECTIVE: Vascular malformations are uncommon pathologic entities in which surgery is usually not possible or is inefficient. Our experience with the percutaneous treatment of peripheral vascular malformations, by means of transarterial embolization or direct puncture is here reported. MATERIAL AND METHODS: During the 1993-1997 period a total of 35 patient, 20 females (57%) and 15 males (43%) aged 11 to 75 years, were treated at our Unit. Sixteen vascular malformations were hemodynamically active (45.7%) and 19 hemodynamically inactive (54.3%). A total of 126 embolizations (mean 3.6) were performed. Malformations were studied by means of doppler-echography, magnetic resonance, arteriography and direct puncture angiography. Considering location, size and hemodynamic characteristics a specific approach and therapy was performed in each case. In two cases (5.7%) a surgical exeresis after embolization was performed. RESULTS: A technical success, defined as the possibility of embolizing the malformation, was achieved in 100% of cases. No technical complications during the procedure occurred. The mean follow-up time was 23 months (6-69). All patients but one improved both objectively and subjectively and all but one have recovered their daily activities in the following days. The exception was one patient who developed a severe complication--cutaneous necrosis--a few days after the procedure which required repairing surgery. All patient had edema, pain and increased functional impairment after the embolization which subsided with medical treatment. CONCLUSIONS: Percutaneous embolization of vascular malformations is an effective method associated with a low complication rate. Our results are encouraging although more extensive investigation are required to draw definite conclusions.
