What surgical procedure typically involves dissecting the saphenous vein?

The procedure that typically involves dissecting the saphenous vein is coronary artery bypass grafting (CABG). In CABG, surgeons use segments of the saphenous vein to create a bypass around blocked coronary arteries. The saphenous vein is harvested from the leg and then grafted onto the coronary arteries to improve blood flow to the heart muscle. This approach is crucial in cases where arterial grafts are necessary, especially for patients who have significant coronary artery disease.

Other procedures listed do not involve the saphenous vein as a graft source. Gallbladder removal involves surgical techniques focused on the biliary system without requiring vein dissection, while open-heart surgery may involve various types of grafts or repairs depending on the specific condition but does not exclusively require the use of the saphenous vein. An appendectomy targets the appendix and likewise does not involve any vein dissection.
