[Contrast of curative effect and complications between peripheral venous thrombolysis and catheter-direct thrombolysis for acute deep venous thrombosis in lower limbs].

Objective: To evaluate the effects of catheter-direct thrombolysis in acute deep venous thrombosis (DVT).

Methods: A total of 86 cases were divided into 2 groups of peripheral venous thrombolysis (group A, n = 33) and catheter-direct thrombolysis (group B, n = 53). The curative effect of two groups was compared by swelling rate and vascular potency.

Results: No significant difference existed in swelling rate between two groups (P > 0.05). Vascular patency rates of group B was significantly better than those of group A (P < 0.01). The incidence of bleeding had no significant difference (P > 0.05) and there was no asymptomatic pulmonary embolism in two groups.

Conclusion: Both treatments of acute DVT are effective in improving symptoms. But catheter-directed thrombolysis results in significant vascular patency rate and does not increase the risk of thrombolytic bleeding.
