(a) Digital subtraction angiogram of the terminal aorta demonstrates bilateral absence of the common iliac arteries. (b) Digital subtraction angiogram of the posterior division of the left internal iliac artery demonstrating the traumatic pseudoaneurysm of the superior gluteal artery. (c) Digital subtraction angiogram of the left internal iliac artery demonstrated successful post-embolisation exclusion of the pseudoaneurysm.
