Clinical application of Solitaire AB stent in assisting coiling embolization for intracranial ruptured and tiny aneurysms

Abstract

Objective To evaluate the application of Solitaire AB stent in assisting coiling embolization for intracranial tiny aneurysms.Methods A total of 9 consecutive patients with intracranial tiny aneurysm were treated with Solitaire AB stent-assisted coiling embolization.The intracranial aneurysms were located at posterior communicating artery (n =4),ophthalmic artery (n =3),top of the basilar artery (n =1) and middle cerebral artery (n =2).Results All the Solitaire AB stent were successfully placed in 9 aneurysms.Of the 9 patients,complete embolization of the lesion was achieved in 6 and partial embolization in 3 without rupture of the aneurysms during the performance.During the follow-up period,no new attack was seen.There was no in-stent stenosis or recurrence of aneurysms in 9 patients who were followed-up by the cerebral angiography from 8 to 13 months.Condusions The endovascular treatment of ruptured and tiny intracranial aneurysms by the stent-assisted coiling technique was safe and feasible.The long-term curative effects of the endovascular emholization on tiny aneurysms might be further improved by increasing the packing density and diverting blood flow.
