Analysis of curative effect of arterial embolectomy with Solitaire AB stent in treatment of acute intracranial large artery occlusion

Abstract

Objective To explore the efficacy and safety of arterial embolectomy with Solitaire AB stent in treatment of acute intracranial large artery occlusion.Methods The clinical data of 11 patients with acute intracranial large artery occlusion receiving arterial embolectomy with Solitaire AB stent from March to December 2013 were analyzed retrospectively.Among them,5 cases were with simple middle cerebral artery occlusion,1 case combined with occlusion in the intracranial part of the internal carotid artery,4 cases had simple basilar artery occlusion,and 1 case had occlusion in the intracranial portion of the vertebral arteries extending to intracranial portion of the basilar artery.Revascularization and postoperative hemorrhage were analyzed,and nosocomial as well as clinical outcomes after 3 months were evaluated.Results Ten patients showed successful revascularization,of which 8 cases reached the standard of perfect revascularization.After embolectomy,there was obvious stenosis in offending vessel of 4 cases,who were given balloon dilatation then.In 3 cases,the vessels were still narrow,so Solitaire AB stent was placed in the stenosis area to correct stenosis with the residual stenosis rate of less than 40％.Thus electrolytic interruption was given.There was no symptomatic intracranial hemorrhage.Three months after the operation,5 cases recovered,among whom 2 cases had obvious curative effect instantly,1 case had complete remissions in 1 week,and 1 case remained hemiplegia.Five cases died,and 4 cases discharged from the hospital because their family gave up the subsequent treatment.Conclusions Arterial embolectomy with Solitaire AB stent to treat patients with acute intracranial large artery occlusion has a relatively higher revascularization rate.The clinical outcome after 3 months can be significantly improved.Thus,it provides a safe and effective endovascular treatment for patients with acute intracranial large artery occlusion.
