Subclavian steal syndrome
Clinical features
- Arm claudication
- Dizziness on exercising
- Decreased pulses in affected arm
- Supraclavicular bruit
Pathogenesis
- Atherosclerosis rarely causes upper limb ischaemia because of good collaterals and decreased frequency of atheroma in these vessels
- If occlusion is in the proximal part of the subclavian artery, patients may experience vertebrobasilar symptoms when they exercise the affected limb.
- The vertebral artery on the side of the stenosis acts as a collateral - blood flow reverses "stealing" blood from the circle of Willis
