Abstract:
Lower extremity deep venous thrombosis (DVT) is estimated to occur in 1 in 1000 persons annually in adult populations, with prevalence predicted to double by the year 2050. While acute DVT and pulmonary embolism are a major cause of cardiovascular morbidity and mortality, the long-term prognosis for patients with venous thromboembolism is in part determined by the development of post-thrombotic syndrome (PTS), which occurs in up to 50% of patients. PTS refers to a chronic syndrome complex, invariably characterized by intractable edema, pain, stasis dermatitis, and venous stasis ulceration when severe.
