RESUMO
Objective:To compare the clinical efficacy of catheter thrombolysis and systemic thrombolysis for deep venous thrombosis of the lower extremities.Methods:102 cases of unilateral deep venous thrombosis of the lower extremities were selected from February 2013 to July 2015 in our hospital.With randomly method divided into the observation group and the control group,each had 51 cases,patients in the control group were treated with systemic thrombolytic therapy,patients in the observation group underwent catheter thrombolysis,also all patients were followed up.The clinical effect was compared between the two groups.Results:In the observation group,thigh swelling rate,leg swelling rate,the patency rate of vein thrombolysis rate were significantly higher than control group;the thrombolysis time of observation group was (5.2 ± 1.7) d,significantly lower than that of control group (6.8 ± 2.1) d,the difference was statistically significant (t=4.229,P=0.000);observation group's cases of vascular patency was significantly higher than the control group,while the residual amount of thrombus was significantly lower than the control group.The differences were statistically significant (P＜0.05).Conclusion:Catheter thrombolysis treatment of lower extremity deep venous thrombosis effect significantly,can shorten the patient's blood flow recovery time,and the deep vein patency rate is far superior to the systemic thrombolysis treatment.
