a The angiography of patient 1 showed a lobulated LC7 aneurysm with the anterior choroidal artery origin from its neck. b According to the measured diameter, different coils are used to densely embolize the two parts of the aneurysm respectively. Leave a little space (yellow circle) at the neck to ensure blood supply to the anterior choroidal artery. c Postoperative angiography showed satisfactory embolization of the aneurysm and perfect preservation of anterior choroidal artery (white arrow). d Follow-up angiography after 3 months showed no aneurysmal recurrence and perfect preservation of the lenticulostriate artery (white arrow)
