The aim of DREAM-PRIDE is to evaluate whether implantation of drug-eluting stent (DES) combined with aggressive medical treatment is more efficacious in prevention of 1-year stroke recurrence than standard medical treatment alone for symptomatic intracranial atherosclerotic disease.
Age from 18 to 85 years
Patients with ischemic stroke within 30 days of enrolment attributed to 70% to 99% stenosis of a major intracranial artery (internal carotid artery [C4-C7], middle cerebral artery [M1], vertebral artery [V4], or basilar artery) on CTA (According to WASID method)
The diameter of the target vessel between 2.0mm - 4.5mm
The stenosis lesion length ≤ 14 mm
Ischemic stroke occurred within 7 days before enrolment
Tandem extracranial or intracranial stenosis (70%-99%) or occlusion that is proximal or distal to the target intracranial lesion (NOTE: an exception is allowed if stenosis or occlusion involves a single vertebral artery proximal to a symptomatic basilar artery stenosis and the contralateral vertebral artery is supplying the basilar artery)
Bilateral intracranial vertebral artery stenosis of 70%-99% and uncertainty about which artery is symptomatic (NOTE: an exception is that if bilateral vertebral arteries with 70%-99% stenosis but unequal in size, the dominant side is considered as symptomatic)
Unilateral vertebral artery stenosis of 70%-99% with normal contralateral vertebral artery
