From the Guidelines
The great saphenous vein (GSV) can be accessed at the level of the saphenofemoral junction, knee, or ankle.
Access Sites for Great Saphenous Vein
- The saphenofemoral junction is a common site for accessing the GSV, particularly for surgical removal or ligation of the vein 1.
- The knee or ankle level can also be used to access the GSV, depending on the specific procedure or treatment being performed 1.
Clinical Considerations
- The choice of access site may depend on the individual patient's anatomy and the specific treatment being performed, such as vein ablation or surgical removal of the GSV 1.
- Preoperative assessment of the GSV, including vein mapping using duplex ultrasound, can help determine the best access site and treatment approach 1.
From the Research
Access Sites for the Great Saphenous Vein
The great saphenous vein (GSV) can be accessed at various sites, including:
- The proximal thigh, as described in a study published in 2009 2, where the GSV can be exposed via a surgical incision for the insertion of central venous catheters.
- The thigh level, as reported in a study from 2014 3, where the greater saphenous vein can be used for the placement of peripherally inserted central catheters in children.
- The ankle level, also mentioned in the 2014 study 3, where the greater saphenous vein can be accessed using anatomical landmarks.
- The medial distal thigh, as discussed in a 2022 study 4, where the great saphenous vein can provide an alternative site for ultrasound-guided cannulation in cases of difficult peripheral venous access.
- The saphenofemoral junction, which is the termination point of the GSV into the femoral vein, as studied in a 2024 cadaveric study 5.
Anatomical Considerations
It is essential to consider the anatomical variations of the GSV, such as duplication and persistence of accessory veins, as well as the presence of tributaries, when accessing the vein 6, 5. These variations can affect the success of the procedure and the risk of complications.
Clinical Applications
The GSV can be used for various clinical applications, including:
