Abstract: Venous thrombosis of lower extremities mainly refers to the abnormal coagulation of the blood in the deep venous cavity of patients, which leads to the obstruction of the venous lumen and further venous reflux disorder. It is a common complication in neurosurgical patients, with unilateral extremity swelling and local pain as the major symptoms, which seriously affect recovery. If interventions are not implemented in time, it will be complicated with other diseases, or even endanger life. Therefore, to reduce venous thrombosis of the lower limbs, it is especially necessary for neurosurgical patients to take effective preventive measures. This paper analyzed and reviewed the pathogenesis and causes of venous thrombosis of lower extremities, as well as preventive nursing measures and effects, aiming to provide evidence for nursing care for neurosurgical patients.
