Deep vein thrombosis (DVT) refers to the formation of thrombus in deep veins, which is common in lower limbs. If not treated in a timely manner, it can lead to serious complications and even endanger life. Ultrasound scanner is a non-invasive examination method that can accurately diagnose DVT. This article will introduce the application of ultrasound scanner in the diagnosis of deep vein thrombosis.

1、 Principles of Ultrasonic Scanners

Ultrasound scanner is a device that uses ultra-high frequency sound waves for non-invasive examination of the human body. The principle is to use the reflection and propagation characteristics of ultrasound between different tissues to determine the structure and state of the organization by measuring the echo time and intensity of the sound waves. Ultrasound scanners can detect blood vessel walls, blood flow velocity, and blood clots, thereby helping doctors diagnose DVT.

2、 Ultrasonic scanner examination method

Vaginal probe method: Suitable for women, it can directly observe the venous conditions in the pelvic cavity.

Abdominal probe method: applicable to men and women, it can observe the inferior vena cava and femoral vein, and has good diagnostic value for detecting deep vein thrombosis of lower limbs.

Percutaneous femoral vein probe method: applicable to patients with fat or shallow deep veins.

Ultrasound Doppler technology: By measuring blood flow velocity and direction, it is possible to distinguish the position and status of normal blood vessels and blood clots.

3、 Application of ultrasound scanner in DVT diagnosis

Quick positioning: Ultrasound scanners can quickly determine the position and range of DVT, thereby helping doctors develop treatment plans.

Observation of blood flow: Ultrasound scanners can observe blood flow velocity and direction, distinguish normal blood vessels and thrombus locations, and are very important for the diagnosis and efficacy evaluation of DVT.

Guided treatment: Ultrasound scanners can guide the treatment process, such as directing drugs directly into the thrombus to improve treatment effectiveness.

Prevention of complications: Ultrasound scanners can detect DVT early and provide effective treatment to avoid serious complications such as pulmonary embolism, lower limb edema, and pain.

4、 The advantages of ultrasound scanner in diagnosing DVT

Non invasive examination: Ultrasound scanner is a non-invasive examination method that does not cause any harm to the patient.

High accuracy: Ultrasound scanners can directly observe blood vessel walls and blood flow, with high accuracy and can quickly diagnose DVT.

Easy to operate: The ultrasound scanner is easy to operate and can be performed in the diagnostic room or bedside.

High safety: Ultrasound scanners do not require the use of any radioactive substances or contrast agents, resulting in high safety.
