Figure 2: Patient 2 - (a) Lateral, (b and c) Oblique views of vertebral digital subtraction angiogram (DSA) showing a giant basilar artery aneurysm high above dorsum sellae. The occipital high flow arteriovenous malformation (Spetzler Martin grade IV; size = 2, venous drainage 1; eloquence = 1) is supplied by left posterior cerebral artery and superior cerebellar artery and drains by multiple feeders into the superior sagittal sinus and left transverse sinus, (d) Postoperative right vertebral DSA showing adequate clipping of basilar apex aneurysm, (e) Operative image showing the aneurysm and the pituitary stalk draped around it, (f) Successful clipping of the aneurysm
