In present study, the minimum length between coeliac trunk and left gastric artery was 0.40 cm, the maximum 2.0 cm and the mean of 1.18 [+ or -] 0.27 cm, and the left gastric artery, as the first branch of the coeliac trunk, was observed in 66 (66.00%) out of the 100 cadavers.
In present study, the length from coeliac trunk up to common hepatic and/or splenic artery had a mean of 1.7 [+ or -] 0.32 cm, with minimum length of 1.0 cm and maximum 3.0 cm in 100 cadavers and the common hepatic artery was present in 28 (28%) cadavers as the last artery, the splenic artery in 6 (6%) and both arteries at the same level, as terminal branches in 48 (48%) out of the 82 studied cadavers.
However, our patient had a different mechanism due to abnormal feeding vessels feeding the pancreatic head from the coeliac trunk
. Also this patient had associated vascular malformations involving subserosal capillaries in the right colon.
The coeliac trunk takes its origin from the abdominal aorta and supplies the stomach, duodenum, liver, gallbladder, spleen and pancreas through its three branches namely splenic artery, left gastric artery and common hepatic artery.
The left side inferior phrenic artery was from the coeliac trunk in 12% of cadavers.
The artery originated from the coeliac trunk
in 90.6% followed by abdominal aorta 8.1% and other sites 0.3%.
Therefore keeping the above mentioned facts in view the continuous reporting of the anomalous branching patterns of the coeliac trunk and also the superior mesenteric artery becomes very important.
Figure 1: Shows the lower origin of the coeliac trunk from the abdominal aorta.
* The most common pattern of branching of the coeliac trunk
was the Hepatogastrolienal type, which has been accepted as the normal pattern of branching of the coeliac trunk
The first one was gastro-splenico-phrenic trunk (in the place of coeliac trunk
) arising at the T12 level, measuring 7 mm in calibre and 2mm in length.
The coeliac trunk
typically gives rise to three major branches, the left gastric artery, the hepatic and the splenic arteries; it may likewise give rise to one or both the inferior phrenic arteries or to a branch, the dorsal pancreatic artery to the pancreas (2).
