Imaging Findings

A lower extremity venous Doppler examination demonstrated arterialization of the venous system from a fistulous connection (Figure 1). Arterial phase computed tomography showed a large contained rupture of a left common iliac artery aneurysm with fistulous connection to the left common iliac vein (Figure 2). The left internal iliac artery was coil embolized (Figure 3). An endovascular stent was placed from the ostium of the left common iliac artery and required extension to the distal aspect of the left external iliac artery to treat a Type I endoleak. The post-angiogram demonstrated successful stenting of the aneurysm without evidence for endoleak (Figure 4).
