atherosclerosis of the internal mammary artery in patients undergoing coronary artery bypass grafting
in patients requiring coronary artery bypass grafting (cabg), usually at least one of the internal mammary arteries is used. this study evaluates the degree of atherosclerotic involvement of the internal mammary artery (ima) in patients undergoing cabg. during two months period, 79 patients (66 male and 13 female with a medium age of 58 years) undergoing myocardial revascularization had a biops...
متن کاملSevere atherosclerosis in the internal mammary artery after aortic coarctation.
A 79-year-old man was scheduled for cardiac bypass surgery and had undergone aortic coarctation repair 41 years ago. Intraoperatively, the left internal mammary artery (IMA) revealed to be tortuous with absent palpable pulses (Fig. 1a and b). We performed a triple coronary artery bypass grafting with three saphenous vein grafts. Histological evaluation of the resected artery showed extensive st...
متن کاملBeta-adrenoceptor-mediated responsiveness of human internal mammary artery
The internal mammary artery (IMA) is currently the preferred conduit for myocardial revascularization. However, pre-operative vasospasm and a hypoperfusion state during maximal exercise may limit its use as a bypass graft. The mechanism of spasm has not been clearly defined. Since β-adrenoceptor activation plays a major role in vasorelaxation, the present study was carried out to investigate th...
متن کاملIdiopathic internal mammary artery aneurysm
Aneurysms of the internal mammary artery are extremely rare, and their presentation and treatment are variable. Since these aneurysms often tend to rupture and cause haemothorax and life-threatening conditions, the knowledge of secure treatment options is indispensable. We here report the case of an idiopathic internal mammary aneurysm in a 46-year-old man. Open surgical resection of the aneury...
متن کاملIsolated left anterior descending coronary atherosclerosis: long-term comparison of internal mammary artery and venous autografts.
A consecutive series of 100 patients receiving left internal mammary artery grafts and a consecutive series of 100 patients receiving saphenous vein grafts as treatment of isolated left anterior descending coronary artery stenosis were reviewed to determine survival, graft patency, disease progression and New York Heart Association functional class. The mean follow-up was 67 months, and the mea...
