2.14\ Longitudinal Scanning

of the Anterior Tibial Artery

Fig. 7.28  Longitudinal section of the anterior tibial artery

ATA

2.14.1\ Scanning Method

The subject takes a supine position or sits. The probe is placed on the anterolateral tibia to scan. The anterior tibial artery runs downward along the anterolateral crus. Its distal segment is located at the front of the crus. One can also scan the anterior tibial artery from the distalsegment.

2.14.2\ Sectional Structure

The cross section shows an round of anterior tibial artery with pulsation. The lumen does not easily become flat when pressed.

2.14.3\ Measurement Methods

The inner diameter of the anterior tibial artery is measured.

2.14.4\ Clinical Significance

This plane can be used to judge whether there is arteriosclerosis obliterans, arterial embolism, thrombosis, arterial aneurysm, or arteriovenous fistula in the anterior tibial artery.

2.15\ Transverse Scanning

of the Anterior Tibial Artery

ATA

ATV

Fig. 7.29  Transverse section of the anterior tibial artery

2.15.1\ Scanning Method

The subject takes a supine position or sitting position; the probe is placed on the anterolateral tibia for scanning. The anterior tibial artery runs downward along the anterolateral crus; its distal segment is located at the front of the crus. One can also scan bottom-up from the distal of anterior tibial artery.

2.15.2\ Sectional Structure

The transverse section of the anterior tibial artery is shown as a ring echogenicity with pulsation. The lumen does not easily become flat when pressed. Crosscutting shows that the anterior tib-

ial artery is round with pulsation; its lumen does not easily become flat when pressed.

2.15.3\ Measurement Methods

The inner diameter of the anterior tibial artery is measured .

2.15.4\ Clinical Significance

This section can be used to judge whether there is arteriosclerosis obliterans, arterial embolism, thrombosis, arterial aneurysm, or arteriovenous fistula in the common femoral artery, superficial femoral artery, and deep femoral artery.

2.16\ Longitudinal Scanning

of the Posterior Tibial Artery

Fig. 7.30  Longitudinal section of the posterior tibial artery

PTA

2.16.1\ Scanning Method

The subject takes the supine or sitting position. The probe is placed on the medial side of the lower leg, and the difference between peroneal arteries. The posterior tibial artery is relatively superficial, so it can be explored from the distal part of the posterior tibial artery.

2.16.2\ Sectional Structure

The long axis section of the posterior tibial artery is shown. Posterior tibial artery is pulsatile; its vascular lumen does not easily collapse.

2.16.3\ Measurement Methods

The posterior tibial artery diameter and blood flow spectrum are measured.

2.16.4\ Clinical Significance

This section can be used to judge whether there is arteriosclerosis obliterans, arterial embolism, thrombosis, arterial aneurysm, or arteriovenous fistula in the posterior tibial artery and to diagnose stenosis or occlusion, thrombosis, and other diseases of the posterior tibial artery.

2.17\ Transverse Scanning

of the Posterior Tibial Artery

Fig. 7.31  Transverse section of the posterior tibial artery

PTA

2.17.1\ Scanning Method

The subject takes the supine or sitting position. The probe is placed on the medial side of the lower leg, and the difference between peroneal arteries. The posterior tibial artery is relatively superficial, so it can be explored from the distal part of the posterior tibial artery.

2.17.2\ Sectional Structure

The cross section of the posterior tibial artery is round and pulsatile; its lumen does not easily collapse.

2.17.3\ Measurement Methods

Tiameter and blood flow spectrum of the posterior tibial artery are measured.

2.17.4\ Clinical Significance

This section can be used to judge whether there is arteriosclerosis obliterans, arterial embolism, thrombosis, arterial aneurysm, or arteriovenous fistula in the posterior tibial artery.
