• grafts
  • For example, the presence of obstructing lesions in an artery may be treated by the use of vascular replacements such as bypass grafts. (google.com)
  • VGF may be identified in asymptomatic patients, but can also produce symptoms of ischemia, depending on the area of the supplied territory of the heart, and the function of native arteries and other grafts. (wikipedia.org)
  • The solutions in which vein grafts are stored after harvesting also play an important role. (wikipedia.org)
  • nerves
  • The No-touch technique is where the vein is harvested with the surrounding tissues, keeping the vasa vasorum and the nerves in the adventitia intact. (wikipedia.org)
  • Opposite the heads of the ribs, the sympathetic trunk passes downward in front of them, and the splanchnic nerves also descend in front by the lower arteries. (wikipedia.org)
  • Sensory supply is from the 7-12 thoracic nerves The sternalis muscle may be a variant form of the pectoralis major or the rectus abdominis. (wikipedia.org)
  • obstruction
  • Atherosclerosis is characterized by yellowish plaques of cholesterol, lipids, and cellular debris deposited into the inner layer of the wall of a large or medium-sized coronary artery, most often resulting in a partial obstruction in the affected artery. (wikipedia.org)
  • Left main coronary artery obstruction requires two bypasses, one to the LAD and one to the LCX. (wikipedia.org)
  • A single obstruction of the left main coronary artery is associated with a higher risk for a cardiac death and usually receives a double bypass. (wikipedia.org)
  • citation needed] The surgeon reviews the coronary angiogram prior to surgery and identifies the number of obstructions, the percent obstruction of each, and the suitability of the arteries beyond the obstruction(s) as targets. (wikipedia.org)
  • arterial
  • Arteriosclerosis is characterized by thickening, loss of elasticity, and calcification of the arterial wall, most often resulting in a generalized narrowing in the affected coronary artery. (wikipedia.org)
  • The grafting exposes the vein to arterial pressure and flow that causes increased shear stress and wall tension, which further damages the endothelial layer and SMC. (wikipedia.org)
  • abdominal cavity
  • The diaphragm separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity and performs an important function in respiration: as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs. (wikipedia.org)
  • laterally
  • The artery winds laterally around the wrist, passing through the anatomical snuff box and between the heads of the first dorsal interosseous muscle. (wikipedia.org)
  • procedure
  • During the procedure, the surgeon typically incises the skin overlying the surface of the vein. (google.com)
  • Atherosclerosis
  • After 5 years the patency rate drops to 65% and at 10 years GSV patency rates are approximately 50%, with only half of the veins are atherosclerosis free. (wikipedia.org)
