1.27.1\ Scanning Method

The patient should be on an empty stomach for 8–12 h, with a supine position. Probe is put on the subxiphoid. After showing the standard transverse scan of the pancreas, probe will scan toward the posterosuperior so that longitudinal section of the common hepatic artery and splenic artery can be obtained Major area: longitudinal section of the common hepatic artery and splenic artery.

1.27.2\ Section Structure

Longitudinal section of the common hepatic artery, proper hepatic artery, splenic artery, and celiac artery is shown. The upper edge of the pancreas and cross section of the inferior vena cave and abdominal aorta.

1.27.3\ Measuring Method and the Normal

Measuring the inner diameter of the common hepatic artery, proper hepatic artery, and splenic artery. The inner diameter of the common hepatic

artery and proper hepatic artery are 0.39 ± 0.07 cm and 0.33 ± 0.07 cm, respectively.

1.27.4\ Clinical Application Value

(1) To judge whether the hepatic artery is obstructed or whether there a presence of anastomotic stenosis or thrombosis by this section in liver transplant patients. That color blood flow interrupts or cannot be shown, and the hepatic artery blood flow that cannot be measured will indicate vascular stenosis or occlusion. (2) The hepatic artery blood flow velocity will be a quick compensatory in the primary hepatocellular carcinoma or portal venous obstructive diseases such as portal vein thrombosis or tumor emboli.

(3)In patients with splenomegaly, the splenic artery may be dilated and velocity will be quick.

(4)If the lymph nodes in the abdomen and retroperitoneum were enlargement they can be displayed around the celiac artery, hepatic artery, or splenic artery by this section.
