Coronary subclavian steal syndrome is a rare ischemic cause in patients after myocardial revascularization surgery. Subclavian artery stenosis or compression proximal to the internal mammary artery graft is the underlying cause. The authors present a clinical case of a patient with previous history of non-ST elevation myocardial infarction, triple coronary bypass, and effort angina since the su...

Subclavian artery stenosis is an uncommon cause of myocardial ischaemia in patients with internal mammary artery grafts. Coronary subclavian steal and impaired flow through the graft are the two mechanisms implied. We report 2 patients with mammary artery grafts in whom reappraisal of anginal symptoms was related to the presence of proximal subclavian stenoses located just before the origin of ...

Transient cortical blindness after coronary angiography or angioplasty is a rare complication. Patients with aortocoronary bypass grafts such as internal mammary artery have a seperate risk factor probably because of the direct contrast injection to the vertebral artery during the catheterisation of the internal mammary artery ostium. In most cases, computed tomography scan revealed typical, sy...

Coronary-subclavian steal syndrome is a rare clinical entity, which results from the atherosclerotic disease of the origin of the subclavian artery in patients in which the internal mammary artery was used as a conduit for coronary artery by-pass. This complication causes reversal of the flow in the internal mammary artery and the recurrence of myocardial ischemia. The therapeutic options are a...

OBJECTIVE Heat shock proteins (HSPs) are molecular chaperones which are essential for cell survival. Heat shock and hypoxia markedly increase the expression of several HSPs in various tissues, i.e. heart. In our in vitro study, we investigated whether HSPs are inducible in human vessels which are used as coronary artery bypass grafts. METHODS We used remnants of the saphenous vein and the int...

In patients with history of coronary artery disease angina pectoris is usually attributed to the progression of atherosclerotic lesions. However, in patients with previous coronary artery bypass graft operation (CABG) using internal mammary artery grafts, great vessel disease should also be considered. Herein we present two patients with history of CABG whose symptoms were suspicious for corona...

Clinical applications for the internal mammary artery include use as an arterial conduit for coronary revascularization and as a recipient artery for microvascular reconstruction of the breast. This study was completed in an attempt to resolve the controversy over which indication should have priority. Five hundred twenty women with breast cancer who underwent breast reconstruction were reviewe...

In coronary artery bypass grafting (CABG), vasospasm of arterial conduits is a significant clinical problem. Unlike the internal mammary artery, the radial artery (RA) is stored in theatre before grafting. Storage induces temperature shocks upon the RA, both following the initial isolation and upon the return of the graft to body temperature. We have studied the effect of temperature changes in...

A technic was developed using a median sternotomy approach, by which triple or double arterial implantation in the myocardium might he carried out, using the right and left internal mammary arteries and the gastroepiploic artery. Triple or double arterial implantations were performed in 32 patients, two of whom died in the ;ostoperative period. Over 90 per cent of the remaining patients have be...

Coronary subclavian steal syndrome with retrograde blood flow in the left internal mammary-coronary bypass graft is a rare but severe complication of cardiac surgery. The authors present a case of a 68-year-old man after coronary-artery bypass grafting using an internal mammary artery. He had been suffering from angina pectoris for the last several years before surgery. The patient was resuscit...
