Thrombotic disease is a serious cardiovascular disease, including venous thromboembolism, coronary thromboembolism, and cerebral thromboembolism. The occurrence of these diseases is closely related to itching substances in the blood, damage to blood vessel walls, and changes in blood flow status. Early diagnosis of these diseases is of great significance for preventing the occurrence of complications. As a non-invasive, repeatable, and relatively safe examination method, medical ultrasound scanners are gradually being widely used in the screening of thrombotic diseases. This article will explore the potential of medical ultrasound scanners in the screening of thrombotic diseases, and elaborate on their advantages and limitations.

1、 Principles and Techniques of Ultrasound

Ultrasound is a mechanical vibration wave that can penetrate human tissues to form ultrasound images. Medical ultrasound scanners use ultrasound to scan blood vessels, which can obtain information such as blood flow status, vascular morphology, and vascular wall structure. Based on the principle of ultrasound, there are many different types of medical ultrasound scanners, including B-ultrasound, color Doppler ultrasound, and vascular ultrasound. In the screening of thrombotic diseases, color Doppler ultrasound is often used to evaluate blood flow velocity and direction, as well as the formation and location of thrombi.

2、 Application of medical ultrasound scanning in screening for venous thromboembolism

Venous thromboembolism is a serious disease that can cause blood clots to form inside venous vessels, leading to vascular blockage. The application of medical ultrasound scanners in screening for venous thromboembolism mainly includes the diagnosis of lower limb deep vein thrombosis and pulmonary embolism. Through ultrasound scanning, doctors can directly observe whether there are abnormal thrombi in deep vein vessels, as well as the location and size of the thrombi. For the diagnosis of pulmonary embolism, medical ultrasound scanners can evaluate the thrombus situation in the pulmonary artery and also observe the blood flow of pulmonary artery branches.

3、 Application of medical ultrasound scanning in screening for coronary artery thromboembolism

Coronary artery thromboembolism is a disease associated with insufficient myocardial blood flow, often leading to myocardial infarction. The application of medical ultrasound scanners in the screening of coronary artery thromboembolism is mainly to evaluate the blood flow status within the coronary artery. Through ultrasound scanning, doctors can observe whether there are plaques and thrombi in the coronary artery, as well as the location and severity of the thrombus. In addition, medical ultrasound scanning can also evaluate the systolic function of the myocardial wall and ventricular function, thereby more comprehensively assessing the cardiovascular health status of patients.

4、 Application of medical ultrasound scanning in screening for cerebral thromboembolism

Cerebral thromboembolism is a common cerebrovascular disease and one of the main causes of cerebral infarction. The application of medical ultrasound scanners in the screening of cerebral thromboembolism mainly evaluates the cerebral blood flow status through ultrasound examination of intracranial and extracranial blood vessels. Through ultrasound scanning, doctors can observe whether there are abnormal thrombi in intracranial and extracranial blood vessels, as well as the location and size of the thrombi. In addition, medical ultrasound scanning can also quantitatively evaluate cerebral blood flow velocity and blood flow, providing important references for the diagnosis and treatment of cerebrovascular diseases.

Conclusion:

Medical ultrasound scanners, as a non-invasive, repeatable, and relatively safe examination method, have important potential for screening thrombotic diseases. It can help doctors diagnose and evaluate thrombotic diseases early, thus taking corresponding intervention measures and reducing the occurrence of complications. However, it should be noted that medical ultrasound scanning has certain limitations in its application in certain specific situations, such as obese patients and vascular abnormalities. Therefore, in practical applications, a comprehensive judgment needs to be made based on clinical symptoms and other auxiliary examination results.
