Incidence of venous thrombosis following peripheral arterial interventions. A prospective study.

BACKGROUND: The objective of the study was to investigate the incidence of deep vein thrombosis (DVT) at the puncture site following peripheral interventions and to assess if there is a difference between using a vascular closure by means of vascular closure systems or compression bandages. PATIENTS AND METHODS: We prospectively included 474 consecutive patients after peripheral arterial interventions. The day after peripheral arterial intervention we performed venous compression ultrasound to exclude DVT in the area of the groin. We recorded management of arterial closure and subsequent antithrombotic treatment of the patient. Four weeks after intervention follow-up was performed by phone to exclude clinical DVT, pulmonary embolism (PE), and death. RESULTS: We included 474 consecutive patients (mean age 69 y; 298 male / 176 female). All patients were under oral antiplatelet therapy. Vascular closure was achieved in 296 patients (62.44%) by Femostoptrade mark followed by compression bandage and in 178 (37.56 %) by using a vascular closure device alone. Sonography revealed no DVT the day after intervention, no clinical PE occurred. Four weeks follow-up showed no DVT, but there was one patient in the compression bandage group who had PE without proven deep vein thrombosis. Two patients died from other reasons than PE. CONCLUSIONS: The immediate and mid-term risk of DVT after peripheral arterial interventions is extremely low and is not increased if compression bandages are used for vascular closure.
