Definitions
- Vertebral artery (VA) provides collateral blood flow to upper extremity because of vascular blockage
- Caused by stenosis/occlusion of proximal subclavian artery (SCA) or, occasionally, brachiocephalic artery
- Leads to reversed flow in VA to perfuse SCA distal to stenosis/occlusion
- Exacerbated by demand for increased arterial blood flow in arm supplied by affected SCA
- Caused by stenosis/occlusion of proximal subclavian artery (SCA) or, occasionally, brachiocephalic artery
