Endovenous laser treatment treats varicose veins using an optical fiber that is inserted into the vein to be treated, and laser light, normally in the infrared portion of the spectrum, [1] shines into the interior of the vein. This causes the vein to contract, and the optical fiber is slowly withdrawn.
[33] All veins which are between the skin and the superficial fascia are tributaries, and all veins which cross the deep fascia to join the deep venous system are perforator veins. [34] Three anatomic compartments can be described, as networks: N1 contains the deep veins, also known as the deep compartment.
Traditionally, varicose veins were investigated using imaging techniques only if there was a suspicion of deep venous insufficiency, if they were recurrent, or if they involved the saphenopopliteal junction. This practice is now less widely accepted. People with varicose veins should now be investigated using lower limbs venous ultrasonography.
The veins will empty due to gravity or with the assistance of the examiner's hand squeezing blood towards the heart. [citation needed] A tourniquet is then applied around the upper thigh to compress the superficial veins but not too tight as to occlude the deeper veins. The leg is then lowered by asking the patient to stand. [citation needed]

Sclerotherapy is one method for the treatment of spider veins, varicose veins (which are also often treated with surgery, radiofrequency, and laser ablation), and venous malformations. In ultrasound -guided sclerotherapy, ultrasound is used to visualize the underlying vein so the physician can deliver and monitor the injection.
