ABSTRACT
Objective To explore the types of variations in the origin of left gastric artery (LGA) using MSCT angiography.Methods The abdominal MSCT angiography data of 1 500 patients were respectively reviewed,in thoses the abdominal aorta,celiac trunk,LGA,common hepatic artery (CHA),splenic artery (SA) and superior mesenteric artery (SMA)were shown clearly.The origins of the LGA and related artries were focused.A new typing method (types Ⅰ-Ⅹ) was established.And the incidence of various types was calculated.Results The normal anatomical origin (type Ⅰ) of LGAwas noted in 1 342 cases (1 342/1 500,89.47%).Eight types of LGA variant origin were identified in 70 cases (70/1 500,4.67%).LGA variant origin combined with celiomesenteric trunk (CMT) were observed in 47 cases (47/1 500,3.13%).The most common type of LGA origin variation was LGA originated from the abdominal aorta combined with CMT (type Ⅴ) which was found in 24 cases (24/1 500,1.60%).And the least common type was the namely LGA,SA,CHA and SMA arose independently from abdominal aorta (type Ⅵ) which was found in 3 cases (3/1 500,0.20 %).LGA originated from SMA (type Ⅷ) was not found in all 1 500 cases.Conclusion There are many kinds of variations in the origin of LGA.The new typing method can contribute the comprehensive and intensive data for understanding the anatomical and radiographic features.
