Iliofemoral Deep Vein Thrombosis: Conventional Therapy Versus Lysis and Percutaneous Transluminal Angioplasty and Stenting - This is a study of 51 consecutive patients with iliofemoral venous thrombosis who were given the option to choose between conventional therapy (Group I) and multimodality therapy (lysis/percutaneous transluminal angioplasty/stenting, Group II). Primary iliofemoral venous patency rates at 1, 3, and 5 years were 24%, 18%, 18%, and 83%, 69%, and 69% for Groups I and II, respectively. Long-term symptom resolution (0-2 CEAP classes) was also achieved in 10/33 (30%) in Group I versus 14/18 (78%) in Group II (P=0.0015). Lysis/stenting treatment was more effective than conventional treatment in patients with iliofemoral vein thrombosis./
