OBJECTIVES: To study the development and progression in time of deep venous valve incompetence with Duplex ultrasonography in combination with distal cuff deflation in patients with a history of deep venous thrombosis (DVT) and to evaluate symptoms of chronic venous insufficiency (CVI).
DESIGN: Prospective cohort study.
MATERIALS AND METHODS: In a long term follow-up study the deep venous system of 24 patients (7 men, 17 women, mean age 51 years) of an initial group of 27 with phlebographically documented deep venous thrombosis were examined with Duplex scanning at two intervals (mean 34 and 86 months) after DVT.
RESULTS: All but one segments recanalised. Deep venous incompetence occurred exclusively in post-DVT segments. At first follow-up 48% of the post-thrombotic segments showed valve incompetence, while at second follow-up this had increased to 60% (p < 0.001). Venous segments of the upper leg mainly contributed to this increase. Our group of 24 patients was too small to find any significant correlation between symptoms, thrombosis and valvular incompetence.
CONCLUSIONS: The development of deep vein valve incompetence after deep vein thrombosis is a progressive process over more than 5 years.
