摘要
Multiple intracranial aneurysms account for 14%-35%of all intracranial aneurysms.Their incidence rate is significantly increased in women,patients with connective tissue disease,and patients with a family history of subarachnoid hemorrhage.Among them,tandem aneurysms are located on the same parent artery and in close proximity to each other.The LEO stent is a self-expanding nickel-titanium braided stent for intracranial vascularization,which is a delivery system that is easy to navigate and position precisely.This case report describes a 68-year-old female patient who was presented with the chief complaints of dizziness for more than a month upon admission to the First Affiliated Hospital,Zhejiang University,School of Medicine.The cerebral angiography established right vertebral artery occlusion,V4 segment of left vertebral artery dissection with two tandem aneurysms,and bilateral internal carotid artery cavernous sinus segment dissection aneurysm.Therefore,we opted to use the LEO stent semi-release assisted coil embolization to treat the vertebral artery V4 segment tandem aneurysms.Some problems encountered during the operation were also considered and discussed.
