Blood flow in the vertebral artery and the upper extremity was studied in five cases of Takayasu's arteritis with subclavian steal by use of ultrasonic Doppler flowmetry and finger plethysmography. The diagnosis of subclavian steal was made by observation of flow reversal in the vertebral artery on the subclavian steal side during grip exercise and, in addition, the vertebral flow change with b...

We report the unusual case of pulsatile tinnitus caused by muscular branches of the occipital artery, which developed to supply the distal vertebral artery after subclavian artery occlusion. Anatomical findings and options of endovascular treatment are discussed. To our knowledge, subclavian artery occlusion causing an objective tinnitus has not been reported.

From the time that coarctation of the aorta was first described by Morgagni in 1771 (cited by Evans, 1933) until 1944, when Crafoord and Nylin (1945) and Gross (1945) independently managed the lesion successfully by a surgical procedure, the lesion remained a curiosity which challenged the descriptive powers of anatomists and pathologists and which proved a diagnostic exercise for clinicians. T...

THE presence of angina in patients scheduled for nonCase 1 cardiac surgery is considered a risk factor for perioperative cardiovascular complications. Myocardial revascularization is an effective treatment for angina; when performed before noncardiac surgery, it decreases cardiac complications compared with medical therapy.223 Patients who undergo myocardial revascularization with internal mamm...

Case Presentation A 90-year-old woman who underwent coronary artery bypass graft surgery 15 years ago was brought to the Emergency Department from her assisted living facility after developing chest pain, dyspnea, and diaphoresis. On arrival, she continued to have chest pain and exhibited signs of congestive heart failure. Her ECG revealed 2-mm ST-segment depressions across the precordium assoc...

The internal mammary artery is the conduit of choice for cardiac revascularization. Atherosclerotic disease of the coronary arteries may simultaneously involve the subclavian artery. Proximal stenosis in the left subclavian artery may result in recurrent myocardial ischemia in patients with a patent left internal mammary artery (LIMA), due to coronary steal syndrome through the LIMA.

conclusions our case is the first report of ivus imaging of subclavian stenosis resulting from takayasu’s arteritis and provides insight into the pathology behind such lesions. introduction takayasu’s arteritis (ta) is a chronic, idiopathic, inflammatory disease that affects large elastic arteries, including the aorta and its main branches. no consensus exists currently on the superiority of su...

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...

Like subclavian artery disease, innominate artery disease can result in reversal of flow in the ipsilateral vertebral artery. Unlike subclavian artery disease, innominate artery disease can also affect cerebral perfusion in the ipsilateral carotid territory, is less well characterized in the literature, and is more challenging to revascularize. Herein, we present two cases of ‘innominate steal’...
