The most minimally invasive technique is known as endoscopic vessel harvesting (EVH), often described as endoscopic vein harvesting when a saphenous vein is used. This type of procedure requires a single 2 cm incision plus one or two smaller incisions of 2–3 mm in length.
Having an intact outer fat pedicle is what differentiates the two main techniques for harvesting saphenous vein grafts. Conventionally, the outer fat pedicle is removed during the harvesting process. It has been proposed that the no-touch technique, leaving the outer fat pedicle intact, will cause less endothelial damage at the time of harvest ...
The same year, American surgeon Michael DeBakey used a saphenous vein to create an aorta-coronary artery bypass. Argentinean surgeon René Favaloro advanced and standardized the CABG technique using the patient's saphenous vein. [53] The introduction of arresting the heart during operation (cardioplegia) made CABG much less risky.
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used for venous access in cases of trauma, and hypovolemic shock when the use of a peripheral venous catheter is either difficult or impossible. The great saphenous vein is most
In these operations, the heart continues beating during surgery, but is stabilized to provide an almost still work area in which to connect a conduit vessel that bypasses a blockage. The conduit vessel that is often used is the saphenous vein. This vein is harvested using a technique known as endoscopic vein harvesting (EVH).
Healthcare providers may use a number of different techniques in order to improve the chances of successful access. Some techniques include using a tourniquet, tapping over the vein, warming the area to dilate the vein, or using an ultrasound to directly visualize the target vein. Near-infrared illumination devices can also be used to help ...
Vein stripping is a surgical procedure done under general or local anaesthetic to aid in the treatment of varicose veins and other manifestations of chronic venous disease. The vein "stripped" (pulled out from under the skin using minimal incisions) is usually the great saphenous vein. The surgery involves making incisions (usually the groin ...
Generally, a vein bypass lasts at least 5 years in 60-70 percent of people. However about one-quarter to one-third of people will need additional procedures and follow-ups to maintain the condition of the graft. [11] To minimise postoperative complications and a second bypass, correct postoperative care and surgical techniques must be used.
