BACKGROUND Ninety-four patients operated due to the diagnosis of pseudoaneurysm between January 1985 and January 2007 have been respectively studied. M ET H O D Fifty-six of the cases were male (59.6%), and 38 were fem ale (40.4%). The most freq uent findings were puls atil mass and the thrill on pseudoaneurysm. The diagnosis was confirmed by classical angiography, Doppler ultrasonography and magnetic resonance angiography. R E S U LT S The location of the pseudoaneurysms were as follows: 50 superfic ial fem oral artery (61.7%), 14 brach ial artery (14.9%), 8 common femoral artery (8.5%), 8 popl it eal artery (8.5%), 6 rad ial artery (6.4%), 4 ulnar artery (4.3%), 2 profunda femoral artery (2.1%), 2 internal carotid artery (2.1%). In etiological examination, penetrating trauma in 61 cases (64.9%) and blunt trauma in 22 cases (23.4%) were observed. The duration between the trauma and pseudoaneurysms surgery ranged from 4 days to 7 years. In addition to aneurysm ectomy in the surgical process , graft interposition with autogenously vein in 45 cases (47.9%), (saphenous vein in 42 cases, and cephalic vein in 3 cases) were preferred. Primary restoration using direct repair in 24 cases (25.5%), end-to-end anastomosis in 20 cases (21.3%) and ligation in 4 cases (4.2%) were applied. Polytetrafluoroethylene graft was used in 1 case (1.0%). Three amput ations (3.2%) and 2 mortality (2.1%) occurred during hospitalization. 41 patients (43.6%) were foll owed-up for 2-60 months per iod. The median follow-up period is 7 months. Recurrence was found in 5 patients (5.3%). The mean time of recurrence is one mount. All of these recurrences were treated by reaneurysmectomy. The patients gained good functional recovery. CO N C L U S I O N S Early restorative operations have positive effects on long term prognosis and best functional results by choosing a suitable operation method before the complications develop in pseudoaneurysms.
