Iliac Arteriovenous Fistula Secondary to Iliac Aneurysm Rupture Associated with Pulmonary Embolism and Anuria

Hepatorenal syndrome from an ilio-iliac arteriovenous fistula: A rare complication from an endoleak

“…2,6 These findings do not occur consistently or uniformly, and may be present in less than half of patients. 2,5,6 Less common symptoms include limb ischemia, acute liver failure, paradoxical emboli, and intestinal angina. 2,6 Ilio-iliac AVF leads to profound physiologic changes with a reduction in afterload creating a steal-like phenomenon where blood is shunted from arterial system to venous system.…”

“…Other causes such as malignancy, intervertebral disc surgery and other iatrogenic injuries have also been described. 2,3,7 The development of an IIAVF results in an anomalous diversion of blood flow from a high-resistance arterial circuit to a low-resistance venous circuit, resulting in a decrease in total peripheral resistance and an increase in venous resistance, venous pressure and blood volume. 8 This results in an elevated heart rate, with increased stroke volume, cardiac output and cardiac work overall manifesting as a triad of clinical findings:…”

“…Initial renal function tests indicate decreased effective circulatory volume, which is nearly always reversible following repair. 3,11 IIAVFs are potentially life threatening and warrant urgent intervention with the primary goals of management being re-establishment of arterial continuity and ideally, closure of the fistula. 10 Historically, IIAVFs were managed with open surgical repair, usually with a Dacron interposition graft and direct suturing of the fistula from inside the aortic lumen.…”

“…Trauma seems to be the main cau- se of arteriovenous fistula between iliac artery and vein (1). It results from gun shot wounds, stab wounds, seat belt trauma and iatrogenic injuries in 84% of patients (4).…”

“…Iliac artery aneurysms mostly occur in association with abdominal aortic aneurysms, either as an extension of the aortic aneurysm to the common iliac artery or as a separate aneurysm of the iliac artery (1). In addition, one third of the patients have contralateral iliac aneurysms (2).…”
