3.5\ Longitudinal Scanning

of the Axillary Vein

Fig. 7.38  Longitudinal view of the axillary vein

3.5.1\ Scanning Method

The subject takes the supine position; probe is longitudinally placed posterior to the thoracic muscle in front of the axillary folds. The transducer shows the axillary artery firstly and then looks for the axillary vein anterior to the axillary artery.

3.5.2\ Sectional Structure

The wall of the axillary vein is thin, the inner diameter is greater than the accompanying artery, and the cross section of them is elliptical without

pulsation. The lumen can be flat when compressed. The diameter of the vein can enlarge when one’s breath is held after inspiration or Valsalva test.

3.5.3\ Measurement Methods

The inner diameter of the axillary vein is measured.

3.5.4\ Clinical Significance

This section can be used to diagnose thrombus, arteriovenous fistula of the axillary vein, and so on.

3.6\ LongitudinalScanning of

the Brachial Vein

3.6.1\ Scanning Method

The subject takes the supine position with the arm stretched out; probe is longitudinally placed inside the biceps brachii.

3.6.2\ Sectional Structure

The wall of upper limb vein pipe is thin, the inner diameter of vein is greater than accompany artery, transection is elliptical without pulsation. The lumencan be pressed to be flat. When one’s breath is held after inspiration or Valsalva test, the diameter of the brachial vein should enlarge.

Generally, brachial vein runs along with brachial artery.

3.6.3\ Measurement Methods

The inner diameter and blood flow spectrum of the brachial vein is measured.

3.6.4\ Clinical significance

This section can be used to diagnose the upper limb vein thrombus, arteriovenous fistula, and so on.

3.7\ Longitudinal Scanning

of the Cephalic Vein

3.7.1\ Scanning Method

The subject takes the supine position with the arm stretched out. The probe is placed on the forearm where the auxiliary vein runs into the subclavian vein and then looks for the cephalic vein along with the external lateral of biceps brachii.

3.7.2\ Sectional Structure

Longitudinal section of the cephalic vein is shown.

3.7.3\ Clinical Significance

This section can be used to diagnose thrombus, arteriovenous fistula of the cephalic vein, and so on.

3.8\

LongitudinalScanning

 

of the Basilic Vein

Fig. 7.41  Longitudinal view of the basilic vein

3.8.1\ Scanning Method

The subject takes the supine position and stretches the arm out; the transducer is placed on forearm where the basilic vein joins the axillary vein and then looks for the basilic vein along with the medial aspect of the biceps brachii.

3.8.2\ Sectional Structure

The wall of the basilic vein is thin, the inner diameter is greater than the accompanying artery, and the transverse section of them is elliptical without pulsation. The lumen can be flat when

pressed. The diameter of the vein can increase when one’s breath is held after inspiration or Valsalva test.

3.8.3\ Measurement Methods

The inner diameter of the basilic vein is measured.

3.8.4\ Clinical Significance

This plane can be used to diagnose thrombus, arteriovenous fistula of the basilic vein, and so on.
