Deep vein thrombosis

Interventions

rhTNK-tPA thrombolytic therapy group:Thrombolytic measures: a thrombolytic duct is placed during the operation, and 16mg rhTNK-tPA is diluted in 500ml 0.9% normal saline after the operation, and then
At levels below 1.0 g/L, thrombolysis should be stopped. b) If the platelet count is less than 80×109/L or more than 20% lower than the baseline value, attention should be paid to the increased risk o
When it is lower than 50×109/L, thrombolysis and anticoagulation should be stopped immediately. c) Monitoring D-dimer: D-dimer can sensitively reflect whether thrombolytic therapy is effective
If the D-dimer continues to increase, thrombolytic therapy can be considered effective. If the D-dimer value decreases from the high value during treatment and gradually tends to normal or maintains a
