Venous disease has a significant impact on quality of life and work productivity. The post-thrombotic syndrome is characterized by chronic, persistent pain, swelling and other signs in the affected limb. About 20-50% of patients develop post-thrombotic syndrome within 1-2 years of symptomatic deep venous thrombosis, and severe post-thrombotic syndrome, which can include venous ulcers, occurs in 5-10% of cases. Treatment options for established post-phlebitic syndrome are limited, but compression stockings after proximal deep venous thrombosis, reduces the incidence of post-phlebitic syndrome by 50%. Subfascial endoscopic perforator surgery has recently become popular as a minimally invasive way to treat chronic venous insufficiency of the lower extremities.
