[0002] Improving the standardized prevention rate of venous thromboembolism is a national safety quality improvement goal for 2021 and 2022. Deep vein thrombosis (DVT) of the lower extremities is a common peripheral vascular disease in clinical practice. It is caused by abnormal coagulation of blood in the deep veins of the lower extremities, blocking the venous lumen and causing venous reflux obstruction. DVT not only causes swelling and pain in the affected limb, but may also cause serious complications, such as pulmonary embolism, posing a threat to the patient's life. Common clinical examination methods include venography, blood tests, and color Doppler ultrasound, but there is still room for improvement in the measurement of lower extremity circumference.
