Hello doctor! May I ask how long is the treatment time for deep vein thrombosis of the lower extremities? What does the sentence below "prognosis of survival over one year" mean in the sentence: “Systemic (or direct catheter) thrombolysis consider indication in case of acute massive thrombosis (greater than 14 years) days) in the pelvis - femoral region, there is a risk of limb necrosis due to arterial compression, the patient's prognosis is over 1 year". Looking forward to your advice, thank you doctor!

Hello, the doctor would like to answer the question: “How long is the treatment for deep vein thrombosis of the lower extremities? ” as follows:
Blood without deep veins in the lower extremities is usually treated with anticoagulation for 3 months. In some cases, anticoagulants were used for more than 3 - 6 months, 12 months or longer depending on the individual patient, on the basis of considering the risk of bleeding: recurrent thrombosis, cyanotic thrombosis (large blood clots cause edema, arterial compression causing cold feet, cyanosis), thrombosis in advanced cancer, hyperactivity disease (deficiency of Protein C, Protein S, anti-Phospholipid syndrome...). Survival prognosis is an estimate of how long each patient can live depending on the nature of the disease. Thrombolytic drugs can be indicated for 2 cases of deep vein thrombosis of the lower extremities: green thrombosis and large, widespread, and prominent symptoms. Both of these types have a high risk of causing foot necrosis, and fibrinolysis can prevent this condition. Using systemic fibrinolysis is infusing the drug through the hand vein, the drug will enter the general circulation, go throughout the body. Catheter fibrinolysis involves placing a catheter into the vein that is thrombus and then infusing the drug directly into the thrombus, in this way the dose of the drug can be reduced and the risk of bleeding is reduced while still being effective.
