Computed tomographic angiography study of variations of the celiac trunk

Abstract

Background 

The celiac trunk, approximately 1.25 cm in length, is the primary branch originating from the abdominal aorta. In humans, it arises from the aorta at thoracic vertebra 12 (T12). The celiac artery is the initial significant branch derived from the descending abdominal aorta, branching at a 90° angle, just below the diaphragm's crus, approximately at the level of the first lumbar vertebra.

The celiac artery has three main divisions, each with its own named branches. It supplies oxygenated blood to the liver, stomach, abdominal esophagus, spleen, and the superior half of both the duodenum and the pancreas.

Material and Method : The study was performed on 100 CT Scan images, 50 males and 50 females with the help of Radiant Dicom viewer software.

Observation and result:-We observed that the most common landmark for the origin of the celiac trunk is at the T12 level, some artery direct origin from aorta such as 5 subjects showing origin of left gastric artery, 2 subjects shows splenic artery, 3, some celiac trunk branches arise from the superior mesenteric artery, the left gastric artery in 1 case, a splenic artery in 4, and a common hepatic artery in 8,

Conclusion: Proficiency in vessel ligation and anastomosis plays a critical role in surgical procedures such as liver transplantation. A comprehensive understanding of the various vascular patterns of coeliac trunk branches is essential to minimize complications associated with abdominal surgery, including bleeding and necrosis.
