Abstract: Conventional coronary artery bypass grafting (CABG) is the most common cardiac surgical procedure for treating coronary artery disease (CAD). The greater saphenous vein (SV) is the most commonly used conduit material for aortocoronary grafting. In cardiac surgery and vascular surgery, external support (or external stent) is a type of scaffold made of metal or plastic material that is inserted over the outside of the vein graft in order to decrease the intermediate and late vein graft failure after bypass surgery (e.g. CABG).. An external support (external stent) should be differentiated from a stent.
Aneurysms of an Aorto-Coronary Artery Saphenous Vein Bypass Graft—A Case Report ALBERTO BENCHIMOL, M.D., F.A.C.A. CHARLES L. HARRIS, M.D. KENNETH B. DESSER, M.D., F.I.C.A. HAROLD FLEMING, M.D. ABSTRACT-SL’MMARY A 62 year old man with severe angina pectoris underwent aorto-coronary saphe- nous vein graft a four month . Introduction. Coronary artery bypass grafting (CABG) is one of the most frequently performed surgical procedures in the United States, with > procedures performed annually. 1 Although CABG improves survival and symptoms in selected patients, 1 – 3 surgical success depends on the continued patency of grafts, and graft failure has been associated with worse outcomes. 4,5 Saphenous vein.

Objectives: Vein graft disease is a major drawback of coronary artery bypass r, histopathologic studies of old human aortocoronary grafts are scarce. Methods: We screened patients undergoing redo coronary artery bypass grafting at three university hospitals and selected those with at least one excisable old vein graft.
Native non-grafted saphenous veins were Cited by: 7. Coronary artery disease (CAD) is a highly prevalent and initial consensus disease afflicting many. Recently, the Heart Disease and Stroke Statistics update of the American Heart Association (AHA) reported a disease prevalence of million persons among those 20 years and older in the USA. The treatment of CAD ranges from medical management and lifestyle modification to invasive.
Aortocoronary saphenous bypass graft has been successfully employed to ablate attacks of intractable angina pectoris due to localized coronary artery disease.1, 2 It would seem, however, that this operation would be of even greater benefit to the patient and represent a greater challenge to the cardiac surgeon and the Aortocoronary saphenous vein bypass graft disease book if it were employed to avoid an impending.
Saphenous vein grafts (SVGs) are the most frequently used conduits for coronary artery bypass graft (CABG) surgery but are associated with year vein graft failure (VGF) rates of 40−50%. Aortocoronary saphenous vein graft disease, with its increasing clinical sequelae, presents an important and unresolved dilemma in cardiological practice.
During the 1st month after bypass surgery, vein graft attrition results from thrombotic occlusion, while later the dominant process is atherosclerotic obstruction occurring on a foundation of.

Effect of aortocoronary saphenous vein bypass grafting on death and sudden death: Comparison of nonrandomized medically and surgically treated cohorts with comparable coronary disease and left ventricular function.
Am J Cardiol Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage") surgery, and colloquially heart bypass or bypass surgery, is a surgical procedure to restore normal blood flow to an obstructed coronary artery.A normal coronary artery transports blood to the heart muscle itself, not through the main circulatory system.
for patients with no disease to 5 for complete occlusion. Significant stenoses between 50 and 90% are scored 2 if single and 3 for multiple lesions. Severe occlusions of 90% or greater are scored 4.
All patients had at least one ACB with saphenous vein graft. Cardiopulmonary bypass was used in all but 26 patients. Most of the 26 had a. The heart-lung bypass machine and the person who runs it may be kept on stand-by just in case the procedure need to be completed on bypass.
The doctor will do the bypass graft procedure by sewing one end of a section of vein over a tiny opening made in the aorta, and the other end over a tiny opening made in the coronary artery just below the.
A year-old man had extensive occlusive disease of the coronary artery and angina pectoris. An autogenous saphenous vein bypass from the ascending aorta to the anterior descending coronary artery was performed on The patient suffered an. The first reported transluminal dilation of an aortocoronary saphenous vein bypass graft was performed Jan 5,at Shadyside Hospital.
The patient had suffered recurrent angina almost six years after bypass surgery to the LAD and right coronary arteries, and coronary cine showed the RCA graft to be closed and disclosed the presence of a.
Graft atherosclerosis, technical errors, and native coronary artery disease progression are common causes of saphenous vein aortocoronary graft failure. Aneurysmal degeneration of these grafts appears to be rare.
There are several reports of pseudoaneurysm formation in saphenous vein. A year-old man who had undergone aortocoronary saphenous vein bypass developed disruption of the proximal aorto-saphenous vein anastomosis.
Although rare, a mediastinal hematoma secondary to leakage or disruption of an anastomotic site should be considered in patients who develop a mediastinal mass after aortocoronary bypass surgery. Campeau L, Enjalbert M, Lespérance J, Bourassa MG, Kwiterovich Jr P, Wacholder S, et al.
The relation of risk factors to the development of atherosclerosis in saphenous-vein bypass grafts and the progression of disease in the native circulation. A study 10 years after aortocoronary bypass surgery.
N Engl J Med. ; (21)– The presumed limited growth potential of saphenous vein grafts has led many authorities to discourage their use in young children. We documented excellent growth and patency of a saphenous vein graft 13 years after operation in a 7-year-old child with coronary artery obstruction caused by Kawasaki disease.
Atherosclerosis is the most frequent cause of occlusion of aortocoronary saphenous vein grafts between 5 and 10 years after coronary artery bypass surgery. The typical atherosclerotic plaque appears between 1 and 3 years after operation and, at a mean of 5 years, histologic changes of atherosclerosis are present in 21% of grafts and in 27% of.
We report two cases of the inadvertent insertion of a saphenous vein bypass graft into the anterior cardiac vein creating an aortocoronary vein fistula.
The clinical recognition, evaluation, and management are discussed. Suggestions on surgical technique to help minimize or eliminate this potential complication daring saphenous vein bypass surgery are proposed.
An invaluable reference for clinicians and researchers alike, this book offers a thorough review and analysis of all aspects of saphenous vein bypass graft disease-from preventive surgical techniques to various mechanisms of graft failure in patients. Assesses the potential for molecular and genetic therapies to improve vascular graft patency!5/5(1).Saphenous vein segments are frequently used as aortocoronary bypass grafts, particularly in patients over 65 years of age.
In the majority of patients, venous grafts maintain their patency for 5–6 years; however, some become occluded within 12 months after surgery.
