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.
Sometimes, the SSV joins the common gastrocnemius vein before draining in the popliteal vein. [2] Sometimes, it does not make contact with the popliteal vein, but goes up to drain in the GSV at a variable level. [1] Instead of draining in the popliteal vein, it can merge with the Giacomini vein and drain in the GSV at the superior 1/3 of the thigh.
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 Giacomini vein or cranial extension of the small saphenous vein [1] is a communicating vein between the great saphenous vein (GSV) and the small saphenous vein (SSV). It is named after the Italian anatomist Carlo Giacomini (1840–1898). The Giacomini vein courses the posterior thigh as either a trunk projection, or tributary of the SSV.
Also, unlike ultrasonography of deep venous thrombosis, the procedure focuses mainly on superficial veins. Also, unlike the arterial ultrasound examination, blood velocity in veins has no diagnostic meaning. Veins are a draining system similar to a low pressure hydraulic system, with a laminar flow and a low velocity.
Used for disease of the femoral and tibial arteries, this procedure is used most frequently in people with diabetes, which tends to create disease in the tibial arteries rather than the more proximal arteries. [4] a "DP" bypass - any vascular bypass where the target is the dorsalis pedis artery on the dorsum of the foot. It is used in similar ...
Unlike arterial ultrasonography, venous ultrasonography is carried out with the probe in a transversal position, (perpendicular to the vein axis), displaying cross-sections of the veins. [4] All collateral veins are better detected this way, including perforator veins, but of most importance is the detection of venous thrombosis.
Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
