Vertebrobasilar Steal Syndrome

Vertebrobasilar steal syndrome refers to posterior-circulation ischemia due to proximal subclavian/innominate artery stenosis that 'steals' vertebral blood flow away from the brainstem. Clinical: vertigo, dizziness, visual disturbance, and limb claudication with arm exercise. Diagnosis: vascular ultrasound/CTA. Treatment: control vascular risk; surgical/endovascular revascularization for symptomatic stenosis.

Common Symptoms

Vertigo/dizziness; visual disturbance; arm claudication; pulse/BP asymmetry; arm exercise triggers symptoms

Causes and Pathogenesis

Proximal subclavian/innominate stenosis reverses vertebral flow, stealing posterior-circulation blood supply.

Treatment

Control vascular risk; endovascular/surgical revascularization for symptomatic stenosis

Preventive Measures

Control vascular risk; antiplatelet; revascularization when indicated.

Department to Visit

It is recommended to visit the Neurology department; an appointment can be booked on this platform before the visit.
