ABSTRACT

Objective: To describe the experience in the management of traumatic arteriovenous fistulas (AVF) in the Military Central Hospital of Bogota-Colombia in the period of 2000 to 2006. Material and methods: In 7 years we evaluated 16 patients with traumatic arteriovenous fistulas, whose diagnosis was confirmed by arteriography and color Doppler Scan. Fourteen were treated with conventional surgery and two with endovascular stents. Results: In a total of 16 patients with average age of 28 years it was seen that the most frequent type of trauma was injury by shot guns with fragmentation (n = 9). The majority of patients presented pain in the extremity (n = 8) edema (n = 12), paresthesias (n = 6) and murmur with thrill (n = 12). The arteriography is the Gold Standard diagnostic test for arteriovenous fistulas identification, the most frequently affected vessels were the popliteal artery and vein (n = 4). The autologous vein graft was the most usual arterial reconstruction treatment (n = 6) and vein ligature (n = 8). Endovascular treatment was carried out in 2 patients obtaining complete resolution of the AVF, with less complications, short procedure time and reduced hospital stay. Conclusions: Traumatic AVF is not a frequent pathology, and the reason why we present these cases, therefore it is very important for hospitals that treat gun shot victims. The gold standard diagnostic test is the arteriography and that the use of autologic venous graft and vein ligature are suitable therapeutic options with excellent results, low morbidity and low mortality with good outcome. Recently endovascular treatment for AVF could offer a better option for this type of injury in terms of less complications, short procedure time, and reduced hospital stay.
