Re-do coronary artery bypass graft (CABG) surgery carries significant risk to the patient and existing patent internal thoracic artery grafts. Stenting stenotic saphenous vein grafts (SVGs) with drug-eluting stents (DES) using embolic protection devices (EPDs) is therefore probably the optimum treatment. However, this is fraught with challenges such as distal ...
Frauenfelder Thomas - - 2007
Coronary artery bypass graft (CABG) surgery represents the standard treatment of advanced coronary artery disease. Two major types of anastomosis exist to connect the graft to the coronary artery, i.e., by using an end-to-side or a side-to-side anastomosis. There is still controversy because of the differences in the patency rates ...
