OBJECTIVES: The aim of the study was to assess venous reflux and the obstruction pattern after catheter-directed and systemic thrombolysis of deep iliofemoral venous thrombosis. PATIENTS: Thirty-two patients treated either with systemic (16) or catheter-directed local thrombolysis (16) for massive iliofemoral thrombosis were identified from the hospital registry. METHODS: Clinical evaluation at follow up was based on the CEAP classification and disability score. Reflux was assessed by colour duplex ultrasonography and standardised reflux testing. A vascular surgeon blinded to treatment established the clinical status of the lower limb following the previous DVT. RESULTS: Valvular competence was preserved in 44% of patients treated with catheter-directed thrombolysis compared with 13% of those treated with systemic thrombolysis (p=0.049, Chi squared). Reflux in any deep vein was present in 44% of patients treated by catheter-directed lysis compared with 81% of patients receiving systemic thrombolysis (p=0.03, Chi squared). Reflux in any superficial vein was observed in 25% vs. 63% of the patients, respectively (p=0.03, Chi squared). There were significantly more patients with venous insufficiency of classes C0-1 in the group treated with catheter-directed thrombolysis. CONCLUSION: In this clinical series venous valvular function was better preserved after iliofemoral DVT when treated with catheter-directed thrombolysis.
