Coronary artery bypass surgery aims to prevent death from coronary artery disease and improve quality of life by relieving angina, the associated feeling of chest pain. [1] The decision to perform surgery is informed by studies of CABG's efficacy in different patient subgroups, based on the lesions' anatomy or how well the heart is functioning.
Coronary artery bypass surgery involves an artery or vein from the patient being implanted to bypass narrowings or occlusions in the coronary arteries. Several arteries and veins can be used, however internal mammary artery grafts have demonstrated significantly better long-term patency rates than great saphenous vein grafts. [40]
Coronary artery bypass graft surgery has been in practice since the 1960s. Historically, vessels—such as the great saphenous vein in the leg or the radial artery in the arm—were obtained using a traditional "open" procedure that required a single, long incision from groin to ankle, or a "bridging" technique that used three or four smaller incisions.
The internal thoracic artery is the cardiac surgeon's blood vessel of choice for coronary artery bypass grafting. The left ITA has a superior long-term patency to saphenous vein grafts [ 6 ] [ 7 ] and other arterial grafts [ 8 ] (e.g. radial artery , gastroepiploic artery ) when grafted to the left anterior descending coronary artery ...
Used for disease of the femoral and tibial arteries, this procedure is used most frequently in people with diabetes, which tends to create disease in the tibial arteries rather than the more proximal arteries. [4] a "DP" bypass - any vascular bypass where the target is the dorsalis pedis artery on the dorsum of the foot. It is used in similar ...
In medicine, vein graft failure (VGF) is a condition in which vein grafts, which are used as alternative conduits in bypass surgeries (e.g. CABG), get occluded. Veins, mainly the great saphenous vein (GSV) are the most frequently used conduits in bypass surgeries (CABG or PABG), due to their ease of use and availability. [1]
Bilaterally, the internal thoracic vein arises from the superior epigastric vein, and accompanies the internal thoracic artery along its course. [1] It drains the intercostal veins, although the posterior drainage is often handled by the azygous veins. [1] It terminates in the brachiocephalic vein. [2] It has a width of 2-3 mm. [3]
Minimally invasive cardiac surgery, encompasses various aspects of cardiac surgical procedures (aortic valve replacement, mitral valve repair, coronary artery bypass surgery, ascending aorta or aortic root surgery) that can be performed with minimally invasive approach either via mini-thoracotomy or mini-sternotomy.
