Lower extremity venous thrombosis does not usually affect the length of life, and most patients can be treated to return to normal with no change in life expectancy. Lower extremity venous thrombosis is a condition in which venous reflux in the lower extremities is impeded due to various reasons, and blood pools and eventually forms thrombi in the lower extremity veins. Pain in the affected limb, chronic ulcers, and bruising of the skin are typical symptoms, and if left untreated, dislodgement of the thrombus may result in a pulmonary embolism. Non-surgical treatment of the disease includes wearing medical compression stockings on the affected limb, avoiding prolonged sitting and standing, and intermittent elevation of the affected limb. Medication is usually low molecular heparin, warfarin and other drugs to anticoagulate, but also urokinase can be used to dissolve the thrombus formed, which has a good effect (do not use your own medication, and be sure to consult your doctor before using medication). If the effect of medication is not obvious, surgical treatment can be used, such as taking intravenous thrombectomy, catheter thrombolysis. If you suffer from lower extremity venous thrombosis, it is recommended to seek medical treatment in time, early detection and early treatment, so as not to delay the condition.
