The garment may be prefabricated or custom-fabricated but must provide adequate graduated compression.Ĭhronic Venous Insufficiency With Venous Stasis UlcersĬhronic venous insufficiency (CVI) of the lower extremities is a condition caused by abnormalities of the venous wall and valves, leading to obstruction or reflux of blood flow in the veins.

Airos compression pump trial#

The trial of conservative therapy must include use of an appropriate compression bandage system or compression garment, exercise, and elevation of the limb. Pneumatic compression devices are covered in the home setting for the treatment of lymphedema if the patient has undergone a four-week trial of conservative therapy and the treating physician determines that there has been no significant improvement or if significant symptoms remain after the trial. Secondary lymphedema, which is much more common, results from the destruction of or damage to formerly functioning lymphatic channels, such as surgical removal of lymph nodes or post radiation fibrosis, among other causes. Primary lymphedema is a relatively uncommon, chronic condition which may be due to such causes as Milroy's Disease or congenital anomalies. Lymphedema is divided into two broad classes according to etiology. The accumulation of lymph fluid results from impairment to the normal clearing function of the lymphatic system and/or from an excessive production of lymph. Lymphedema is the swelling of subcutaneous tissues due to the accumulation of excessive lymph fluid. Pneumatic devices are covered for the treatment of lymphedema or for the treatment of chronic venous insufficiency with venous stasis ulcers.
