Traumatic arteriovenous fistulas and aneurysms at the Tikur Ambessa hospital, Addis Ababa

چکیده
During the years 1 9 9 2 1 9 9 6 11 cases of arteriovenous fistula or aneurysm were reported in the Department of Surgery at Tikur Anbessa Hospital (TAH). Ten of these cases will be presented. Eight of the cases were operated upon in 1996. The mean age of the patients was 32 years (range 17-49). Nine were men. The aneurysms were located in the lower extremities in eight patients, and in the upper extremities in two. Eight of the injuries leading to aneurysms involved military personnel and there were two civilians. The mean time of operation after injury was 48.9 months (range 2-72 months). Of these, five were false aneurysms and five were arteriovenous fistulas. In all cases restoration of arterial and venous flow after excision was successful. All these s have been followed for a minimum of four months after surgery (range 4-31 months). Results were considered excellent in one patient and good in nine. however, often followed by ischemia and gangrene1. The standard treatment of quadruple ligation of AV fistulas was introduced by surgeons like Halsted and Holman in the beginning of the twentieth century1. Subsequently, with experience in treating war injuries, particularly during the Korean conflict of 1950-53 and with the rapid development of vascular surgery, the feasibility of immediate repair of all acute arterial injuries was demonstrated2. Where A-V fistulas and false aneurysms did develop after trauma, restoration of arterial continuity, following excision, produced superior results to those of ligation when major vessels were involved2. The present study of traumatic A-V fistulas and aneurysms was made in the light of these advances in the surgical treatment of vascular trauma.
