Feasibility and efficacy of Atlas stents using the waffle-cone technique for intracranial aneurysms with significant branch vessels arising from the aneurysm neck
Objective To explore the feasibility and efficacy of the waffle-cone technique with Atlas stent in the embolization of intracranial aneurysms with significant branch vessels arising from the aneurysm neck.Methods The clinical data of 10 patients with intracranial aneurysms with significant branch vessels arising from the aneurysm neck treated with Atlas stent-assisted embolization from January 2022 to September 2022 were retrospectively analyzed.Results DSA revealed significant branch vessels arising from the aneurysm neck in all patients,and the waffle-cone technique was adopted for assisted embolization during the operation.Postoperative angiography showed that all the stents were in good position,all the aneurysms were densely embolized,the blood flows of the parent arteries and the branch vessels were patent,and no hemorrhagic or ischemic events occurred.Eight patients were followed-up by DSA at 6 months after the operation,and no aneurysm recurrence was found and the parent arteries were patent.Two patients were lost to follow-up.Conclusions For intracranial aneurysms with significant branch vessels arising from the aneurysm neck,by taking advantage of the characteristics of the distal open loop,precise release,and anchoring of the Atlas stent,the distal part of the stent can be placed at the aneurysm neck to form the waffle-cone technique,protecting the significant branch vessels and supporting the coils,which can increase the density of the coils in the aneurysm sac and protect the branch vessels.
