Causes

Despite ongoing research, the cause of PTS is not entirely clear. Inflammation is thought to play a role [1][2] as well as damage to the venous valves from the thrombus itself. This valvular incompetence combined with persistent venous obstruction from thrombus increases the pressure in veins and capillaries. Venous hypertension induces a rupture of small superficial veins, subcutaneous hemorrhage[3] and an increase of tissue permeability. That is manifested by pain, swelling, discoloration, and even ulceration.[4]
