How can we detect the risk of abdominal aortic aneurysm in advance through ultrasound screening?
An abdominal aortic aneurysm (AAA) is a localized dilation of the abdominal aorta that is larger than 3 cm in diameter or more than 50% larger than normal. Although most AAAs do not cause symptoms, severe pain and other danger signs only occur when they rupture, so early screening is crucial.
Why is screening so important?
A ruptured abdominal aortic aneurysm can be immediately life-threatening. According to statistics, the mortality rate of ruptured abdominal aortic aneurysm can be as high as 90%. Therefore, ultrasound screening can help detect this potentially fatal disease early and manage it, reducing the risk of death.
Main advantages of ultrasound screening
"Ultrasound screening is a safe, non-invasive and effective method for early identification of abdominal aortic aneurysms."
Ultrasound screening can not only accurately measure the diameter of the arteries, but also evaluate blood flow, helping doctors make timely treatment decisions. For men over 65 years old who have the habit of smoking, this examination is recommended to be performed regularly to detect potential abdominal aortic aneurysm early.
Screening criteria and populations
In the United States, the Centers for Disease Control and Prevention (USPSTF) recommends one ultrasound screening for men aged 65 to 75 who have ever smoked. In the UK, screening is generally required for men over 65 years of age. The specific screening criteria are as follows:
- All men over 65 should have a screening ultrasound.
- If the artery diameter is found to be greater than 3 cm, follow-up examinations should be performed regularly depending on the specific situation.
"Screening can significantly reduce the risk of death from abdominal aortic aneurysm, and regular screening is crucial for high-risk groups."
Appropriate treatment options
Once an abdominal aortic aneurysm is detected during ultrasound screening, your doctor will develop a treatment plan based on the size and growth rate of the aneurysm. In cases where the diameter exceeds 5.5 cm, surgical repair is usually recommended. The main surgical methods are open surgery and endovascular repair (EVAR), the latter of which is popular due to its short hospital stay and low risk of death.
Additional precautions
In addition to regular screening, the following lifestyle changes can also effectively reduce the risk of abdominal aortic aneurysm:
- Quit smoking: This is one of the best ways to reduce your risk of abdominal aortic aneurysm.
- Control blood pressure: High blood pressure is an important factor in the formation of aneurysms.
- Maintain a healthy weight: Being overweight increases your risk of several cardiovascular diseases.
Conclusion
Awareness and early screening for abdominal aortic aneurysm can save lives. Advances in medical technology have made ultrasound screening an effective tool to help improve patient survival rates. In this case, are you ready to do regular screening to protect your health?
