Perfusion of dominant left subclavian artery during thoracic aortic aneurysm operation.
A case of aneurysm of the descending thoracic aorta with dominant left vertebral artery and poor cross-collateral circulation is reported. We believe that in such a patient perfusion of the dominant left subclavian artery is a safe method to prevent vertebrobasilar ischemia during thoracic aortic aneurysm operation under normothermia.
