Acquired arteriovenous fistulas and associated aneurysms: Our experience of 20 cases

ABSTRACT

A series of 20 cases of acquired arteriovenous fistulas and associated aneurysms of the lower extremity is presented. Ninety percent of them were following the penetrating injuries, nine cases [45%] had quadruple ligation and excision of the fistula done with no incidence of arterial insufficiency during follow up of at least 3 years. Two out of 7 vascular grafts [30.3%] got infected and six patients [30%] had post operative wound infection in spite of adequate antibiotic coverage, this was probably due to the presence of metallic splinters near the vessels from the time of original injury
