Highlights • Rare complications of vascular trauma. • Challenging diagnosis. • Frequent association to false aneurysm. • Therapeutic choice depends on the rapidity of diagnosis.
Introduction Traumatic Arteriovenous Fistulas (AVFs) are a rare complication of vascular injuries and pose a problem of topographic diagnosis and therapeutic management. Delayed treatment may cause cardiac and trophic complications. Presentation of cases We describe 4 cases of AVFs complicating stab wounds of the lower limb, associated in 2 cases with pseudoaneurysms. Discussion In two cases we performed a surgical repair, whereas in the other 2 patients we choose an endovascular treatment with wall graft stent placement. Conclusion All traumatic AVFs must be treated to avoid vascular, local and general complications. Using both techniques, we had great results with no complications.
