•3. Possibility to perform stenting within two weeks after randomisation
•4. Stenosis of the vertebral artery of 50% or greater, diagnosed by both duplex ultrasound and computed tomography (CT-), contrast-enhanced magnetic resonance (MR-), or conventional angiography, and presumed to be of atherosclerotic origin and accessible for endovascular treatment
•5. Score on the modified Rankin scale less than or equal to 3 (independent in daily activities, although some help may be needed)
•6. Aged 40 years or older, either sex
•7. Written informed consent

•1. Potential cause of TIA or minor stroke other than stenosis in a vertebral artery (e.g. atrial fibrillation)
