Clinical research in individual information of celiac artery CT imaging and gastric cancer surgery.
OBJECTIVE
The objective of this study is to acquire CT images of the celiac artery by 64-multi-slice spiral CT angiography (64-MSCTA) in gastric cancer patients to facilitate gastric cancer surgery.


METHODS
Preoperative 64-MSCTA was performed to observe the origin, course and anatomical variations of the celiac artery and vascular calcifications in 102 gastric cancer patients.


RESULTS
(1) The celiac trunk mostly arose at the level between the 12th thoracic vertebra and the 1st lumbar vertebra; the mean inferior angle with the abdominal aorta was 63.5° (14°-159°), the mean length was 36.29 mm (5.80-73.58 mm), and its course showed many styles. (2) Of 102 gastric cancer patients, 34 patients (33.33 %) were observed with celiac artery variations of whom there were 27 patients with anatomical variations of the hepatic artery, 3 patients with anatomical variation of the left gastric artery and 1 patient with anatomical variation of the splenic artery; in 1 patient, the celiac trunk and the superior mesenteric artery originated from a common trunk. In other cases, it was observed with another variation. (3) The abdominal aortic calcified plaque was observed in 48 patients (47.1 %), and among them, 34 patients were more than 60 years old, and the existence of the abdominal aortic calcified plaque was related to age, significantly (P < 0.01).


CONCLUSIONS
The 64-MSCTA largely improves our understanding of the origin, course and anatomical variations of the celiac artery and vascular calcifications in individual patient with gastric cancer. It is recommended that the 64-MSCTA of the celiac artery should be classified as a routine preoperative procedure in gastric cancer patients.
