Treatment of internal iliac artery pseudoaneurysm by an endovascular approach.

Pseudoaneurysms of the internal iliac artery are uncommon and are usually associated with trauma. We report the case of a 32-year-old man with a 15-day history of trauma to the abdomen and edema of the lower left limb. An arteriogram demonstrated proximal occlusion of the popliteal artery and a pseudoaneurysm in the internal iliac artery. Embolization of the pseudoaneurysm was performed using segments of guide wire that occluded the pseudoaneurysm, followed by proximal occlusion, which was accomplished using coils. An arteriogram after the procedure revealed adequate occlusion of the lesion. This association of guide wires and coils is a treatment option in cases of pseudoaneurysm of the internal iliac artery with large volumes needing to be occluded.
