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 the legs, bypass grafting is used to treat peripheral vascular disease, acute limb ischemia, aneurysms and trauma.While there are many anatomical arrangements for vascular bypass grafts in the lower extremities depending on the location of the disease, the principle is the same: to restore blood flow to an area without normal flow.
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.
The great saphenous vein is exposed and the common femoral and subsartorial veins are identified before dividing. The vein is ligated close to the junction with of the femoral vein. [ 3 ] If the ligation is distal from the saphenofemoral junction , it will leave out small tributaries which may later cause recurrence of varicosities.
The GSV, a superficial vein, is the longest vein in the body. It has its origin in the dorsal venous arch of the foot, a superficial vein which connects the small saphenous vein with the GSV. It travels up the leg and medial side of the thigh to reach the groin, where it drains into the common femoral vein. [32]
