Bilateral internal iliac occlusion – Cardiology MCQ

Potential complication/s of bilateral internal iliac occlusion due to a stent graft:

a) Gluteal claudication

b) Erectile dysfunction

d) All of the above

Correct answer: d) All of the above

Gluteal necrosis can occur in severe cases of gluteal ischemia. Bladder ischemia is another potential risk.

Coil embolisation of internal iliacs is resorted to for preventing type II endoleak when the aortic stent grafts needs to be extended into the external iliac arteries.
