Case 7: 68-year-old woman. A) Pancisternal subarachnoid haemorrhage. B) Acute angiography disclosed a moderate in size and wide neck aneurysm of the basilar artery apex giving rise to the superior cerebellar and posterior cerebral arteries. A Neuroform stent was positioned with its distal tip in the left posterior cerebral artery. C) During release of the first coil the proximal tip of the stent migrated into the aneurysm to lie superior to the right posterior cerebral artery. D,E) Lateral and anteroposterior views: at the end of the procedure the aneurysm is partially excluded from the circulation (80%) preserving patency of the superior cerebellar and posterior cerebral arteries. F,G) MR angiography follow-up after three months shows the stent is patent with a flow signal in the superior cerebellar and posterior cerebral arteries. The superior portion of the aneurysm is completely excluded from the circulation.
