Fallah of the Mallinckrodt Institute of Radiology, Washington University School of … Coronary-subclavian steal — A coronary-subclavian steal phenomenon has been described in patients who have undergone prior coronary artery bypass surgery (CABG) using the internal mammary artery (IMA) . The prevalence of subclavian artery stenosis is 2.5 to 4.5 percent in patients referred for coronary artery bypass grafting . Twenty-nine percutaneous balloon dilations of the axillary and subclavian veins were performed in 19 patients. Stenoses occurred in typical locations of anatomic narrowing or at sites of previous trauma. The initial success rate was 76%, with a 1-year patency rate of 35% and a 2-year patency rate of 6%. 2009-01-01 proximal left subclavian artery (LSA) stenosis in patients referred for isolated coronary artery bypass grafting, and assessed management by percutaneous transluminal an-gioplasty (PTA) for LSA stenosis and revascularization usingtheleftinternalthoracicartery,orrevascularization using grafts other than the left internal thoracic artery.

Nearly 25% of ischaemic strokes involve the vertebrobasilar circulation, and arteriosclerotic disease and narrowing of the proximal VA may be the cause for up to one-fifth of these incidents. “Subclavian steal” refers to a syndrome of symptoms relating to arterial insufficiency in a branch of the subclavian artery stemming from flow reversal,attributable to occlusive disease in the subclavian artery proximal to that branch that is usually atheroscleroticin cause. Most patients are asympt … Introduction: Subclavian artery aneurysms are rare, they affect less than 1% of the population.Symptoms are caused by thrombosis or embolisation reinforcing the need to repair due to risk for rupture, embolisation and thrombosis, which can cause upper limb extremity ischaemia. Although subclavian or innominate artery stenosis is not rare (occurring in 17% of 6,534 cases in the joint study of extracranial arterial occlusion ) flow reversal within the vertebral artery is present in a minority of these cases (2.5% in the same study), and of those with angiographic steal, only 5.3% (9/168) had neurologic symptoms.

Subclavian steal syndrome (SSS), also called subclavian steal steno-occlusive disease, is a constellation of signs and symptoms that arise from retrograde (reversed) blood flow in the vertebral artery or the internal thoracic artery, due to a proximal stenosis (narrowing) and/or occlusion of the subclavian artery. Right Arch with Aberrant left subclavian The Right Aortic Arch with an aberrant left subclavian is an obstructing arch anomaly. The first branch of the aorta is the left common carotid, followed by the right subclavian artery and the left common carotid. This also is a true ring.
