subclavian steal


Also found in: Dictionary, Thesaurus, Legal.

steal

 [stēl]
diversion of something from its normal course, usually referring to blood flow in occlusive arterial disease.
subclavian steal in occlusive disease of the subclavian artery, a reversal of blood flow in the ipsilateral vertebral artery from the basilar artery to the subclavian artery beyond the point of occlusion; this may deprive the brain of blood and cause the subclavian steal syndrome.

sub·cla·vi·an steal

obstruction of the subclavian artery proximal to the origin of the vertebral artery; blood flow through the vertebral artery is reversed and the subclavian artery thus "steals" cerebral blood, causing symptoms of vertebrobasilar insufficiency (subclavian steal syndrome); manifested during vigorous use of an upper extremity.
