Subclavian steal despite ipsilateral vertebral occlusion
Journal of Vascular Surgery
|November 1, 1985
Summary
Vertebral artery occlusion does not rule out subclavian steal syndrome. Reverse flow in collateral neck vessels can cause vertebrobasilar insufficiency, relieved by carotid subclavian bypass in two patients.
Area of Science:
- Vascular Surgery
- Neurology
- Cerebrovascular Disease
Background:
- Subclavian steal syndrome classically involves reverse flow in the vertebral artery due to subclavian artery stenosis.
- Vertebrobasilar insufficiency presents with neurological symptoms stemming from inadequate blood flow to the brainstem and cerebellum.
