1.29.1\ Scanning Method

The patient should be on fast for 8–12 h with a supine position. Probe is put on the subxiphoid. After showing longitudinal scan of the common hepatic artery, probe will scan toward the right posterosuperior so that longitudinal view of the proper hepatic artery can be obtained.

1.29.2\ Section Structure

Longitudinal section of the common hepatic artery and proper hepatic artery is shown. The common hepatic artery gives off the gastroduodenal artery in the right outside the pancreatic head and then becomes a proper hepatic artery. Oblique section of the inferior vena cava and right liver, right portal vein, and celiac artery. The upper area of the pancreatic head. Cross section of the abdominal aorta.

1.29.3\ Measuring Method and the Normal

Measuring the inner diameter of the common hepatic artery and proper hepatic 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.

1.29.4\ Clinical Application Value

(1) To judge whether there are obstruction and whether there is a presence of anastomotic stenosis or thrombosis of the hepatic artery 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 a 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 the patients with splenomegaly, splenic artery may be dilated and velocity will be quick. (4) If the lymph nodes in the abdomen retroperitoneal appear enlarged, they can be displayed around the celiac artery, hepatic artery, or splenic artery by this section.
