Study Of Different Modes Of Catheter-directed Thrombolysis And Peripheral Intravenous Thrombolysis In Lower Extremity Deep Venous Thrombosis

Objective: To evaluate the catheter-directed thrombolysis and peripheral intravenous thrombolysis in lower extremity deep venous thrombosis effect.Methods: Lower extremity deep venous thrombosis of 51 cases of hospitalized patients, divided into catheter-directed thrombolysis and peripheral intravenous thrombolysis .15cases of peripheral intravenous thrombolysis and catheter-directed thrombolysis in 36cases.Results: The mean follow-up of 110months, peripheral intravenous thrombolysis:3 cases were curded,9 Significantly improved,3 improved,,there is no valid cases;before treatment thing circumference difference 5.58±2.17cm,treating later circumference difference1.85±0.85cm,detumescence rate(60.2±25)%;calf circumference difference 4.53±1.83cm,treatment of late circumference difference 1.64±0.59cm,detumescence rate (59.9±20)%; thrombolysis rate(41.2±11.5)%。catheter-directed thrombolysis: 12 cases were curded,16 Significantly improved,8 improved,,no valid cases;before treatment thing circumference difference 5.10±2.97cm,treating later circumference difference 1.55±0.85cm,detumescence rate(60.0±24)%;calf circumference difference 4.05±1.90cm ,treatment of late circumference difference 1.37±0.81cm,detumescence rate (63.7±20)%thrombolysis rate(60.7±19.4)%.Between detumescence rate and treatment, catheter-directed thrombolysis and peripheral intravenous thrombolysis are not statistically significant clinical effect (p>0.05). But thrombolysis rate are statistically significant clinical effect (p<0.01).Conclusion: Catheter-directed thrombolysis and peripheral intravenous thrombolysis are effective in lower extremity deep venous thrombosis, but catheter-directed thrombolysis is better vein patency and valve to maintain the integrity.to reduce deep vein thrombosis.
