coronary artery bypass graft (CABG),

a surgical procedure in which damaged sections of the coronary arteries are replaced with new articular of venous graftings to increase rate of cardiac blood flow.

coronary artery bypass graft

n. Abbr. CABG
A surgical procedure in which a section of a vein is grafted between the aorta and a coronary artery below the level of an obstruction in that artery.

coronary artery bypass graft

CABG pron, cabbage Cardiology A procedure in which vascular grafts, usually saphenous veins–legs, rarely cephalic veins, are anastomosed end-to-side to the internal mammary arteries, bypassing atherosclerotically stenosed coronary arteries; the internal mammary artery might be a better donor, given its relative resistance to collapse; internal mammary procedures are associated with ↑ survival, better long-term patency, ↓ rate of reoperation Statistics 800,000/yr–US survive acute MI–200,000 do not; up to 350,000/yr undergo CABG,23 of whom may benefit from the procedure Indications Pts with coronary lesions that are unsuitable for, or do not respond to, catheter-based intervention; perioperative death and MI are 4% and 10% higher, respectively, when CABG is performed urgently rather than electively; thus efforts should be made to stabilize the Pt pharmacologically before attempting revascularization; an intra-aortic balloon pump–IABP can serve as a bridge to catheterization or revascularization as long as the Pt does not have severe peripheral vascular disease, significant aortic insufficiency, or known severe aortoiliac disease, including aortic aneurysm; Pts who do not stabilize after IABP placement should be reevaluated to confirm the diagnosis of ischemic heart disease and considered for emergency catheterization Medical therapy vs CABG; it is unclear whether medical therapy–diet, exercise, and cholesterol-lowering drugs is more beneficial than surgery; medical therapy is preferred in those without evidence of myocardial ischemia, and in Pts with 1- or 2-vessel disease without significant LADS; CABG is indicated in Pts with chronic stable angina who are medical 'failures', Pts with 2-vessel disease and left anterior descending coronary artery stenosis–LADS; CABG is also indicated in 2- or 3-vessel disease; 'triple bypass' CABG is indicated for unstable angina and ischemia detected by an exercise stress test Presurgery workup EKG, stress test, echocardiography, coronary angiography Complications Progression of ASHD, recurrent angina, arrhythmia, sudden death, within 5 yrs in ± 2% of surgically treated and ± 6% of medically treated Pts Recovery ± 7-10 days.
