Venous thrombosis

In the condition of venous blood flow retardation, hypercoagulable state of blood, and vascular endometrial injury, acute non-purulent inflammation occurs in the vein, and the disease is secondary to thrombosis. Most venous thrombosis occurs in the deep veins of the pelvis and lower limbs. More common in postpartum, fractures and trauma, postoperative patients. The possibility of this disease should be considered in the case of limb pain, swelling, flared superficial veins, and cords that are palpable along the veins. Ultrasound Doppler and radionuclide venography can help diagnosis. Thrombosis is easy to fall off early, which can cause large pulmonary infarction, which is often one of the causes of sudden death. Therefore, early streptokinase or urokinase should be used for thrombolytic therapy, followed by anticoagulant therapy with heparin or coumarin drugs to prevent the formation and spread of thrombus.
