great saphenous vein การใช้

• When it occurs in the leg, the great saphenous vein is usually involved, although other locations are possible.
• A 1996 study reported a 76 % success rate at 24 months in treating saphenofemoral junction and great saphenous vein incompetence with STS 3 % solution.
• They can communicate the great saphenous vein with the small saphenous vein, ( for example the Giacomini vein ) or the superficial venous system with the deep one.
• In surgeries, the principle superficial neurovascular bundles at risk are, medially, the great saphenous vein and its accompanying nerve, and laterally, the superficial peroneal nerve.
• A study by Kanter and Thibault in 1996 reported a 76 % success rate at 24 months in treating saphenofemoral junction and great saphenous vein incompetence with STS 3 % solution.
• It transmits the great saphenous vein and other smaller vessels including the superficial epigastric artery and superficial external pudendal artery, as well as the femoral branch of the genitofemoral nerve.
• The great saphenous vein ( GSV ) is a superficial vein which connects with the small saphenous vein ( SSV ) to drain into the common femoral vein ( CFV ).
• During the procedure, a catheter bearing a laser fiber is inserted under ultrasound guidance into the great saphenous vein ( GSV ) or small saphenous vein ( SSV ) through a small puncture.
• However, some physicians do not perform these procedures at the time of the ELT because the varicose veins can improve on their own as a result of reduced reflux from the great saphenous vein.
• The lateral wall of the sheath is vertical and is perforated by the lumboinguinal nerve; the medial wall is directed obliquely downward and lateralward, and is pierced by the great saphenous vein and by some lymphatic vessels.
• The efferents of the popliteal glands pass almost entirely alongside the femoral vessels to the deep inguinal glands, but a few may accompany the great saphenous vein, and end in the glands of the superficial subinguinal group.
• In the other, a great saphenous vein is removed from a leg; one end is attached to the aorta or one of its major branches, and the other end is attached to the obstructed artery immediately after the obstruction to restore blood flow.
• The great saphenous vein is the conduit of choice for vascular surgeons, when available, for doing peripheral arterial bypass operations [ see vascular bypass ] because it has superior long-term patency compared to synthetic grafts ( PTFE, PETE ( Dacron ) ), human umbilical vein grafts or biosynthetic grafts [ Omniflow ].
• Graft patency is dependent on a number of factors, including the type of graft used ( internal thoracic artery, radial artery, or great saphenous vein ), the size of the coronary artery that the graft is anastomosed with, and, of course, the skill of the surgeon ( s ) performing the procedure.
