The most common was phlebotomy, or venesection (often called "breathing a vein"), in which blood was drawn from one or more of the larger external veins, such as those in the forearm or neck. In arteriotomy , an artery was punctured, although generally only in the temples.
In contrast, phlebectomy is the removal of a vein. Phlebotomies that are carried out in the treatment of some blood disorders are known as therapeutic phlebotomies. [3] The average volume of whole blood drawn in a therapeutic phlebotomy to an adult is 1 unit (450–500 ml) weekly to once every several months, as needed. [4]
The procedure involves the removal of the varicose veins through multiple small 2–3 mm incisions in the skin overlying the varicose veins. First the veins are marked with the patient in standing position. Then the patient is positioned on the operating table and local anesthesia is applied. Incisions are made using a surgical blade.
Typically, a prominent vein in the forearm such as the median cubital vein would suffice, although the Keidel vacuum can take blood for any prominent peripheral vein. This concept did not become popular until during World War II , when quick and efficient first aid care was necessary in the battle field.

This name for handheld venipuncture devices first appears in Anglo-Saxon manuscripts around 1000. [1] The name is most likely derived from phlebotome: phlebos, Greek for blood vessel and tome, meaning to cut. [2] These instruments are the progression from the early use of fish teeth, sharpened stones, and thorns used to penetrate blood vessels.
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 This causes the vein to contract, and the optical fiber is slowly withdrawn.
