@entity1 @entity4905 @entity3526 @entity63
OBJECTIVE: To study the experience in the treatment of @entity3526 ( @entity3526 ) and the relation between @entity3526 and the damage of brain. METHODS: In 28 @entity1 with @entity3526 , 23 were operated on. They complained of vertigo, @entity4905 , and claudication of arms. One @entity1 suffered from severe stem @entity63 spasm. All the @entity1 were subjected to subtraction angiography. Fifteen of them showed retrograde flow in the vertebral arteries. Transcranial Doppler revealed retrograde blood flow in 8 @entity1 . Single photon emission tomography showed inadequate blood supply to the brain with affected subclavian arteries in 4 @entity1 . Carotid-subclavian arterial bypass was performed in 16 @entity1 , axilloauxillary bypass in 3, PTA in 1, and aorta-carotid graft bypass in 3. RESULTS: 13 @entity1 (13/23) had their cerebrovascular symptoms relieved. Transcranial Doppler and emission tomography after operation showed nothing abnormal. CONCLUSION: @entity3526 is harmful and the @entity1 should be closely monitored by means of transcranial Doppler and emission tomography.
