Abstract

Objective: to evaluate the morphology of the branches of celiac trunk (CT), left gastric (LGA), common hepatic (CHA), and splenic (SA) arteries in cadaveric specimens from a sample of a Colombian population. Methods: descriptive cross-sectional study of 26 blocks from the abdominal upper segment of human cadavers who underwent forensic autopsies at the Instituto de Medicina Legal at Bucaramanga, Colombia. The vascular beds of the celiac trunk were, subsequently, perfused with a semi-synthetic resin. Results: the diameters of LGA, CHA, and SA were 3.6±0.8mm, 5,2±1.2mm, and 5.9±1.0mm, respectively. Statistically, LGA and SA were different (p=<0.001). SA followed a linear trajectory in 8 (31%) samples, slightly tortuous in 4 (15%), and tortuous in 14 (54%). The tortuosity index was 1.25±0.18. Of the branches of CHA, the proper hepatic artery (PHA) had 4.8±1.2mm in diameter and 18.8±9.1mm in length, whereas the gastroduodenal artery (GDdA) had 4.1±0.8mm. In 2 cases (7.7%), an accessory hepatic artery from the LGA was found to supply perfusion to the left hepatic lobe. Finally, in 2 cases (7.7%) the SA came independently from the abdominal aorta. Conclusion: the observed emergence incidence of the CT branches from the same level as reported in the literature is lower. The characterization, along with their variants, of LGA, CHA, and SA must be considered in surgical procedures in the upper abdominal segment, to avoid iatrogenic complications.
