Opinion statement
Understanding the anatomical pathways and clinical presentations for VBI are of the utmost importance due to the potential mimics that may occur. After identification of the entity, imaging must be performed to identify the etiology. Distinguishing external compression of the vertebral artery from intrinsic vascular disease due to atherosclerosis or dissection is critical to aid the clinician in the therapeutic decision tree. Patients with an external compression due to an osteophyte may benefit from definitive surgical decompression and excision of the bony structure. Patients with extracranial disease of the vertebral artery who have failed maximal medical therapy may benefit from angioplasty and stenting which appears to carry a low morbidity. Extracranial vertebral artery dissections can be treated with medical therapy using anti-platelet agents or on occasion anti-coagulation. Rarely, endovascular options are required if a patient is having hemodynamic stroke or TIAs due to flow failure. In such circumstances, stenting and angioplasty may be considered. Intracranial atherosclerosis is best managed with maximal medical therapy due to the high rate of complications attributable to stenting and angioplasty.

AJNR Am J Neuroradiol. 2012;33(10):1939–44. The diagnosis of vertebrobasilar insufficiency has traditionally been based on a history of transient brainstem symptomatology with radiographic evidence of steno-occlusive disease, and possibly stroke, within the posterior circulation. Novel techniques such as arterial spin-labeling, as protocols are refined, may provide objective evidence of hemodynamic compromise in the vertebrobasilar territory.

While carotid endarterectomy and stenting are established therapies for secondary prevention of stroke, a large randomized trial is still required to determine the efficacy of stenting for extracranial vertebral stenosis. This review of the existing literature demonstrates that endovascular intervention is low-risk at that anatomic site.

SAMMPRIS was a randomized trial comparing angioplasty and stenting of symptomatic intracranial atheromatous lesions, including intracranial vertebral and basilar stenoses, with medical therapy. While stenting was associated with an unacceptable 30-day stroke risk (14.7 %), risk reduction with aggressive medical therapy was superior to that described in prior studies (5.8 %).
