Prophylactic Left Internal Mammary Artery Graft In Mildly-Stenosed Coronary Lesions. Still an Open Discussion
نویسندگان
چکیده
It has been well established that coronary venous grafts in arteries with moderate atherosclerotic lesions (<70%) had early occlusion mainly due to flow competition with the native coronary circulation. Otherwise, to graft a moderately stenosed coronary vessel with LIMA remains debatable, keeping the question by Hayward and colleagues open: “Should all moderate coronary lesions be grafted during primary coronary bypass surgery?”.2 However, controversy exists whether LIMAs should be used to bypass coronary arteries with noncritical stenoses.3

Coronary artery steal syndrome in patient after coronary arteries by-pass surgery and left subclavian artery stenting: is the maintenance of a patent internal mammary artery still necessary?
[email protected] The use of the left internal mammary artery (LIMA) is preferred for the revascularization of a stenosed or occluded left anterior descending artery (LAD). Occlusion or stenosis of proximal part of the left subclavian artery (LSA) could induce reverse blood flow in LIMA called coronary subclavian steal syndrome (CSSS) and should be revascularized before coronary artery bypass ...

PURPOSE OF REVIEW Arterial grafting is superior to venous grafting in coronary artery bypass graft surgery with respect to graft patency and long-term patient outcome, but it may be difficult to achieve complete arterial revascularization. RECENT FINDINGS Use of arterial grafts, especially bilateral internal mammary artery grafts, is not common, whereas there are clear indications that it may...

To the Editor: I read with interest the dramatic case report by Egred et al.1 However, I was somewhat puzzled by the indication of a left internal mammary artery graft insertion into the left anterior descending coronary artery at the time of the emergency thromboembolectomy. Although the patient had suffered an anterolateral non–Qwave myocardial infarction 2 months previously, coronary arterio...
متن کاملNear-fatal kinking of mammary graft due to emphysematous lung disease
Left internal mammary artery grafting is commonly used in elective coronary artery bypass graft surgery. We report a near-fatal case with graft kinking upon sternal closure due to distended, emphysematous lungs impinging on the mammary graft. After the sternum was closed, the patient suffered a severe hemodynamic deterioration. Surgical examination revealed kinking of his left internal mammary ...
متن کاملTotally Occluded Grafted Right Internal Mammary Artery to Anomalously Originated Right Coronary Artery
An anomalous aortic origin of a coronary artery is rare and surgical intervention is recommended when the patient is symptomatic. We performed coronary artery bypass graft surgery in a 21-year-old male patient with a right coronary artery anomalously originating from the left coronary sinus. The artery was significantly stenosed by external compression between the aorta and the pulmonary artery...
