Arterial diameter of the celiac trunk and its branches: anatomical study

Abstract

Purpose: Despite the fact that anatomical variations of the celiac trunk are well explored in the literature, information on these vessels diameters is scanty. The aims of the present study were to describe the arterial diameters of the celiac trunk and its main branches, and to investigate if these diameters are altered in those cases presenting anatomical variations of these vessels. Methods: Twenty-one formalin fixed adult male cadavers were appropriately dissected for the celiac trunk identification and arterial diameter measurements. Arteries measured included the celiac trunk and its main branches (splenic artery, left gastric artery and common hepatic artery), as the proper hepatic artery, right gastric artery, the left and right hepatic arteries and the gastroduodenal artery. Results: From the 21 cadavers, 6 presented anatomical variations of, at least, one of the above mentioned branches. The average arterial diameter comparisons between groups (normal and variable) clearly showed smaller diameters for variable vessels, but with no significant difference. Conclusion: Our data indicates the possibility of a diameter reduction of the celiac trunk main branches in the presence of anatomical variations. This should be taken into account on the selection for the liver transplantation donors.

Variant anatomy of the celiac trunk –review of literature with a case report

“…The previous study conducted by Tiwari 20 and Petrella 25 showed the origin of RIPA alone from the CT in 2% and 5.62%, LIPA alone in 4% and 21.35%, whereas both IPAs in 4% and 7.86% respectively. The origin of LIPA from the LGA is also described in the literature 7,21,22,33,38 . The knowledge of this type of variation shows that surgeons must be cautious to avoid unintentional sectioning of small calibre arteries, as it may occur during the coeliac artery decompression.…”

“…IJBAR (2014) 05 (10) www.ssjournals.com The hepatosplenic trunk (Type II) and separate LGA from the aorta have been reported in the literature 10,[13][14][15][16]18,21,22,36,37 . The LGA commonly arises from the CT as one element of its trifurcation.…”

Morphometric analysis of the vertebral level of origin of the coeliac trunk and its length

“…8 Silveira et al suggested doing more studies on CT length and diameter based on above observations as they are useful for vascular surgeons and to prevent iatrogenic injuries. 9 Unfortunately to analyze further, CT diameter has not been measured in our study.…”

A study concerning morphometry of abdominal aorta branches and abdominal viscera: relations and correlation

“…To the best of our knowledge, our study is the first to perform statistical comparison in a mixed sample selected under the same criteria and prove this assumption correct. Finally, few studies [36,72,92] have stated that existence of anatomic variation could alter a vessels' morphometry. We have chosen to discard cadavers presenting variations interfering with results of this study.…”
