Abstract
We report the case of a 38-year-old man with a traumatic arteriovenous fistula between the left common femoral artery and vein, resulting from a gunshot wound sustained 20 years earlier. He began presenting symptoms, including a venous stasis ulcer and cardiac dysfunction, 4 years ago. Computed tomography revealed the presence of a fistula and downstream dilation of the iliac vessels and inferior vena cava, the latter measuring up to 37.5 mm. Given the patient’s complex vascular anatomy and overall good clinical condition, an open surgical approach was selected, resulting in excellent outcomes. Due to the risk of deep vein thrombosis and pulmonary thromboembolism, placement of an inferior vena cava filter and initiation of long-term anticoagulation were also performed. Surgery proved to be the definitive treatment, resolving both heart failure and ulcer, and restoring the patient’s quality of life. The open approach was an excellent treatment option, considering the patient’s young age, anatomical distortion, and the unavailability of adequate endovascular materials.
