Abstract：Distal developmental abnormalities of the vertebral artery are not uncommon in clinic;however,theses patients with basilar artery fenestration malformations are rare,and those with associated aneurysms are even rarer.This article reports a case of a 50-year-old female who was admitted to hospital due to sudden headache for 14 hours;the Hunt-Hess score upon admission was grade Ⅱ;emergency cranial CTA revealed subarachnoid hemorrhage and basilar artery fenestration malformation;right vertebral artery angiography showed basilar artery fenestration malformation with an aneurysm,approximately 2.6 mm×2.7 mm in size,and the aneurysm neck was about 2.8 mm.Stent-assisted embolization of the intracranial aneurysm was performed.Immediate angiography after the operation showed complete embolization of the aneurysm,patency of the parent artery,and good visualization of the fenestration channel;at the 12-month follow-up DSA,no recurrence of the aneurysm was observed,and the original fenestration channel was not visualized;there was no new cerebral hemorrhage,cerebral infarction,or neurological deficits.Clinically,the combination of distal developmental abnormalities of the vertebral artery,basilar artery fenestration malformation,and associated aneurysms is extremely rare.DSA is recommended for diagnosis,and endovascular treatment is suggested.Attention should be paid to protecting branch vessels and the fenestration ring as much as possible;the use of stent-assisted embolization may increase the risk of ischemic events,and precautions should be taken.
