Popis: | Arterial grafts include internal mammary, radial, and gastroepiploic artery grafts. Internal mammary artery grafts are the preferred conduit for coronary bypass graft surgery because of excellent long-term patency, whereas there is ongoing controversy on the role of radial artery grafts. Most internal mammary artery graft lesions occur at the distal anastomosis and can be treated with balloon angioplasty or implantation of a drug-eluting stent. Percutaneous coronary intervention of internal mammary grafts can be hindered by graft tortuosity, leading to target vessel ischemia upon wiring and difficult equipment delivery. Radial artery grafts are prone to spasm, especially early after implantation; hence, aggressive vasodilator administration is recommended before percutaneous coronary intervention to exclude spasm. Gastroepiploic grafts are infrequently used for coronary bypass graft surgery and may be difficulty to identify if bypass anatomy is not known at the time of angiography. If needed, arterial graft revascularization can be performed with high procedural success and low risk of complications. |
