Abstract
Objective: To evaluate the comparative effectiveness of two distinct balloon pressure band compression regimens on the treatment outcomes for deep vein thrombosis (DVT) and venous blood flow velocity in the lower limbs of patients undergoing anterograde thrombolysis through the superficial dorsalis pedis vein.
Methods: A total of 42 patients diagnosed with DVT were enrolled in the randomized controlled trial. Patients in the control group received balloon pressure band compression positioned 15 cm above the bony landmark of the medial malleolus of the affected limb, with continuous inflation and deflation. On the basis of the control group, a balloon pressure band was also used 15 cm above the bony landmark of the medial malleolus and 10 cm below the midpoint of the patella in the affected limb in experimental group, with rotational inflation at these two sites. The thrombolysis effects and venous blood flow velocity of the lower extremities were compared between the two groups.
Results: The differences in limb circumference and Marder scores of patients in the experimental group were significantly lower than those in the control group, while the detumescence rate and venous patency rate of the affected limbs in the experimental group were significantly higher than those in the control group (P < 0.05). After 30 and 60 min of thrombolysis, femoral and popliteal vein blood flow velocities in the experimental group were significantly higher than those in the control group (P < 0.05). After 45 min post-thrombolysis, the femoral vein blood flow velocity in the experimental group remained significantly higher than that in the control group (P < 0.05), though no significant difference was observed in the popliteal vein blood flow velocity (P > 0.05).
Conclusion: In this study, alternating balloon pressure band compression applied at 15 cm above the bony marker of the medial malleolus and 10 cm below the patellar midpoint to block superficial venous blood flow was found to enhance thrombolysis efficacy and significantly improve venous blood flow velocity in the lower extremities among patients with DVT.
期刊介绍：
Thrombosis Journal is an open-access journal that publishes original articles on aspects of clinical and basic research, new methodology, case reports and reviews in the areas of thrombosis.
Topics of particular interest include the diagnosis of arterial and venous thrombosis, new antithrombotic treatments, new developments in the understanding, diagnosis and treatments of atherosclerotic vessel disease, relations between haemostasis and vascular disease, hypertension, diabetes, immunology and obesity.
