7  Vascular System Scanning

149

 

 

2.3.1\ Scanning Method

The subject takes the supine position, the palm facing upward. The probe is transversely placed in front of the axillary folds. The arm is completely relaxed and is in march (military) posture when the axillary artery is examined.

2.3.2\ Sectional Structure

The long axis of the axillary artery is shown in the longitudinal section, and the axillary artery is accompanied by the axillary artery, and the axillary artery is pulsed and its lumen does not easily become flat when pressed.

2.3.3\ Measurement Methods

The inner diameter and blood flow velocity of the axillary artery are measured.

2.3.4\ Clinical Significance

To diagnose stenosis or occlusion, thrombosis, and other diseases of the axillary artery, namely, thoracic outlet syndrome (the axillary artery and vein are pressed) as well as the lesions from the structures around the axillary artery such as axillary lymph nodes which are showed to be hypoechoic nodules surrounding the axillary artery.

2.4.1\ Scanning Method

The subject takes the supine position, the palm facing upward; the probe is transversely placed in front of the axillary folds. The arm is completely relaxed and is in march (military) posture when the axillary artery is examined. After showing the long axis of the axillary artery, the probe rotates 90° vertically to the long axis section.

2.4.2\ Sectional Structure

The short axis section of the axillary artery and axillary vein can be shown in this plane. The axillary artery is pulsatile and its lumen does not easily became flat by pressure.

2.4.3\ Measurement Methods

The inner diameter of the axillary artery was measured.

2.4.4\ Clinical Significance

This section is used to diagnose stenosis or occlusion, thrombosis, and other diseases of the axillary artery, namely, thoracic outlet syndrome (the axillary artery and vein are pressed) as well as the lesions from the structures around the axillary artery such as axillary lymph nodes which are shown to be hypoechoic nodules surrounding the axillary artery.
