BACKGROUND Communicating occupying lesions of the intratemporal fossa and mid-cranial fossa represent challenges for neurosurgeons and maxillofacial surgeons. Lesions of the skull base, with complex anatomy, are extremely varied in their histopathology. They often spread via normal anatomic pathways or bony destruction to involve adjacent structures,(More)
BACKGROUND AND PURPOSE The long term results of vertebral artery ostium (VAO) stenting remain uncertain. We sought to evaluate the incidence and risk factors for recurrent ischemic events on long term follow-up in patients who have undergone VAO stenting. METHODS 190 consecutive patients who had undergone a total of 202 stenting procedures for symptomatic(More)
BACKGROUND AND PURPOSE Thrombelastography (TEG) is widely used for the measurement of platelet function. However, few studies have investigated the TEG parameters in patients receiving extracranial or intracranial artery stenting for ischemic cerebrovascular disease. This study sought to describe the association of TEG parameters before the procedure with(More)
OBJECTIVE To determine the safety and efficacy of endovascular treatment with the Solitaire device for acute basilar artery occlusion (ABAO) and identify factors affecting clinical outcomes. METHODS We enrolled 36 consecutive ABAO patients (aged 58.6 ± 8.10 years) who underwent mechanical thrombectomy with the Solitaire device. We analyzed baseline(More)
BACKGROUND AND PURPOSE High periprocedural complication rate is a key limitation of endovascular treatment of intracranial atherosclerotic disease (ICAD), despite potential risk reduction of recurrent stroke. Taking lessons from the Stenting and Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Arterial Stenosis (SAMMPRIS) trial,(More)
OBJECTIVES Symptomatic intracranial vertebrobasilar artery stenosis (IVBS) carries a high annual risk of recurrent stroke. Endovascular therapy was a promising technique but recent trials suggest it may carry a risk of periprocedual complications especially in inexperienced hands. This prospective study was to evaluate the safety of endovascular therapy for(More)
OBJECTIVE To study the feasibility and safety of transradial artery access for endovascular intervention of severe intracranial vertebrobasilar stenosis for selected patients not suitable for transfemoral access. METHODS This was a retrospective analysis of 58 patients who had undergone intervention for severe intracranial vertebrobasilar stenosis using(More)
BACKGROUND Hyperperfusion syndrome (HPS) is a rare but potentially a life-threatening complication after carotid artery angioplasty and stenting (CAS). Staged CAS has been an alternative to prevent HPS. MATERIALS AND METHODS 44 of 908 patients with high-grade internal carotid artery stenosis or near occlusion were at risk of HPS because of poor collateral(More)
BACKGROUND AND PURPOSE Early recanalization of acute posterior circulation stroke due to large intracranial vessel occlusion by mechanical thrombectomy with stent retrievers may improve the outcome of patients. However, evidence of patient selection is still lacking. The study investigated the prognostic factors of acute posterior circulation stroke due to(More)
