Rare Occipital Artery Pseudoaneurysm After Radical Neck Dissection.

Pseudoaneurysm formation in the occipital artery, post radical neck dissection, leading to a bulging mass, is a rare but potentially fatal occurrence. The authors treated a patient with pseudoaneurysm of occipital artery, post radical neck dissection, presenting with pain and swelling after 17 days of surgery. A pseudoaneurysm involving occipital artery was revealed by digital subtraction angiography and treated by endovascular micro-coil embolization.
