Sclerotherapy can also be performed using microfoam sclerosants under ultrasound guidance to treat larger varicose veins, including the great and small saphenous veins.
The great saphenous vein is the most important superficial vein of the lower limb.
Doctors must use high frequency ultrasound during the procedure to visualize the anatomical relationships between the saphenous structures.
It pierces the vascular lacuna near the saphenous hiatus and supplies the skin below the inguinal ligament (i.e. proximal, lateral aspect of femoral triangle).
Venous access was obtained through a preexisting femoral venous line in six patients, and through a cutdown of the saphenous or femoral vein in the other three.
The saphenous vein is less satisfactory when used as a graft in terms of its long-term patency, particularly in young children less than 8 years old.
It is also doubtful that whether the saphenous vein, when used as a free graft, has the potential to grow in a fashion corresponding to overall growth of the patient.
Behavioral testing was performed within the sciatic and saphenous innervation area of the hind paws as described previously.
