Thrombectomy Combined with Indwelling-catheter Thrombolysis is more Effective than Pure Thrombectomy for the Treatment of Lower Extremity Deep Venous Thrombosis.

Abstract

This study was a retrospective analysis of the efficacy of thrombectomy plus local catheter-directed thrombolysis (CDT) for the treatment of lower extremity deep venous thrombosis (LDVT). The experimental group underwent thrombectomy plus LCDT, whereas the control group underwent thrombectomy plus systemic thrombolysis via the dorsalis pedis vein. Venography and vascular color Doppler ultrasound were performed 7 days after surgery and at follow-up. The differences in the thigh and calf circumferences of normal and affected limbs were compared between groups. The venous patency score and venous patency rate were used for outcome evaluation. Compared with the control group, the experimental group showed a lower venous patency score and higher venous patency rate after treatment (P<0.05). Thirty patients were followed for 3 to 6 months, and according to the last evaluation, the differences in thigh and calf circumference between the normal and affected limbs remained lower in the experimental group than in the control group (P<0.05). Moreover, the venous patency score was lower, and the venous patency rate was higher in the experimental group than in the control group (P<0.05).

CONCLUSION:

Thrombectomy plus CDT yields a higher venous patency rate and lower recurrence rate than pure thrombectomy for the treatment of LDVT.
