Continuous-wave Doppler ultrasonography and clinical examination were used over a 2-year period to monitor the natural history of subclavian stenoses and occlusions in 67 patients. Thirty-nine presented with subclavian steal and 28 without. We also studied an additional group of 29 patients who had undergone surgery for subclavian steal syndrome and vertebrobasilar transient ischemic attacks. T...

The Subclavian Steal Syndrome is a condition that results from the stenosis or occlusion of the subclavian artery proximal to the origin of the vertebral artery. The blockage causes the reversal of the normal direction of blood flow in the vertebral artery which is termed the "steal", because it steals blood from the cerebral circulation. Blood is drawn from the contralateral vertebral, basilar...

We report a case of coronary-subclavian steal syndrome, which had been masked by a malfunctioning hemodialysis access vessel and then reappeared after a successful angioplasty of multiple stenoses in the arteriovenous fistula of the left arm in a 61-year-old man. This case suggests that coronary-subclavian steal syndrome should be considered before a coronary artery bypass grafting surgery usin...

In the evaluation of the extracranial carotid circulation for occlusive disease, duplex sonography was used routinely to determine the direction of flow in the vertebral arteries. Of 600 patients examined, 15 were found to have reversed flow in a vertebral artery-the subclavian steal syndrome. This was confirmed in the seven patients who underwent angiography. Duplex sonography was found to be ...

Blood flow to the brain was studied in 11 patients suffering from subclavian steal syndrome. The venous isotope-dilution method was used to measure total blood flow to the brain and the dye-dilution method with intravenous administration of 50 mg of Evans blue was used to determine cardiac output. Cerebral blood flow was significantly lower in the 11 patients with subclavian steal syndrome than...

We describe a case of recurrent pulmonary edema after hemodialysis despite the patient being at ideal dry weight. Coronary-subclavian steal syndrome can cause serious complications in end-stage renal disease patients on hemodialysis. This is a case of subclavian steal, made worse by hemodialysis, using an upper limb hemodialysis fistula. Complete resolution of symptoms followed percutaneous ste...

The coronary subclavian steal syndrome (CSSS) leading to an acute myocardial infarction (AMI) post-coronary bypass is a rare occurrence. We describe an 83-year-old Indian man who presented with AMI and was subsequently found to have CSSS. The patient had severe stenosis of his left subclavian artery ostium with retrograde flow up his left internal mammary artery graft. Angiographical steal from...

Literature data on the etiology, clinical picture, diagnostic variants and treatment of subclavian steal syndrome are reviewed. Different clinical variants and neurological symptoms of the syndrome are described. Multispiral computed tomography, along with ultrasound examination, is important in the diagnosis of the syndrome and its causes. The use of other methods is necessary for more accurat...
