Hi doctor! May I ask how long it takes to treat 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 - thigh, 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!
