(a) Lateral and (b) AP right carotid angiograms show a complex proximal internal carotid aneurysm involving the cavernous, clinoidal and supraclinoid carotid. This aneurysm could not be reconstructed with clips and was treated by trapping and revascularization with a saphenous vein graft from the cervical ICA to the middle cerebral artery. (c), and (d) are postoperative angiograms demonstrating the patency of the bypass.
