a, b Patient 2 presented with acute SAH and the initial CTA showed a huge aneurysm at the tip of the basilar artery. c The 3D rotational angiogram showed many perforating arteries on the dome of the aneurysm (yellow circle). d We used different diameters coils to embolize the main part of the aneurysm body, leaving a certain space at the dome of the aneurysm. e Postoperative angiography showed satisfactory embolization of the aneurysm and perfect preservation of perforating arteries on the dome of the aneurysm (white circle). f Follow-up angiography after 4 months showed no aneurysmal recurrence and perfect preservation of the lenticulostriate artery
