Angina pectoris and coronary bypass surgery: Patterns of prevalence and recurrence in 3105 consecutive patients followed up to 11 years

Intravascular Gamma Radiation for In-Stent Restenosis in Saphenous-Vein Bypass Grafts

“…Recurrent stenosis involving vein grafts accounts for substantial morbidity and mortality, with cardiac events developing in 6 percent of patients per year. 16 Although balloon angioplasty of saphenous-vein grafts has been associated with rates of recurrent stenosis that exceed 50 percent, stenting has not solved the problem of restenosis. 6,7,10,11 Our findings confirm the efficacy of gamma radiation for the treatment of in-stent restenosis, even in patients with diffuse lesions.…”

Distal anastomotic lesions after coronary artery bypass surgery: Incidence, pathogenesis, and treatment approach

“…Coronary artery bypass surgery (CABG) is an established form of revascularization and has been shown to improve symptoms in more than 80% of patients . Annually, however, 8% of patients return with recurrent symptoms due to progression of native vessel disease or failure of the graft itself . Angiographic studies have shown occlusive disease at the anastomotic site or in the graft itself in >1/3 of patients in the 10 years after surgery ; and distal anastomosis lesions are the most common reason for venous graft failure .…”

Optimal Revascularization Strategies for Percutaneous Coronary Intervention of Distal Anastomotic Lesions after Coronary Artery Bypass Surgery

“…Coronary artery bypass surgery (CABG) is an established revascularization strategy and has been shown to improve symptoms in >80% of patients . After CABG, annually 5% of patients return with recurrent symptoms due to progression of native vessel disease or failure of the graft itself . A major determinant of graft patency is the type of the graft used; saphenous vein grafts (SVGs) tend to fail much more when compared to internal mammary artery grafts .…”
