Abstract

Aim:To evaluate the variations of coeliac trunk and superior mesenteric artery variations in Tekirdag province using computed tomography (CT) images. Methods: The data of the patients who underwent CT angiography for any reason via the hospital online PACS system were scanned retrospectively for celiac trunk and superior mesenteric artery variation. The frequency of variation in the study population, the variation type and distribution by gender were statistically analyzed. Results: A total of 2529 individuals, including 1703 (67.3%) men and 826 (32.7%) women, were included in the study. The prevalence of variation in the study group was 25.7% (n=650), and it was seen that there was a single variation in 579 (89.1%) individuals and a double variation in 71 (10.9%) individuals. The three most common variations were replaced right HA, LGA orginated replaced left HA, and common HA from SMA origin ( n= 340, 13.44 % ; n=120, 4,74 % and n=46, 1.82 %, respectively). Conclusion: Information the rates of these vascular variations provides contribution to surgical procedures and prevents more serious complications. Also, it should be carefully investigated in terms of other accompanying variation.

Highlights

The aorta abdominalis (AA) is the continuation of the descending aorta after passing the midline diaphragm through the hiatus aorticus at the lower edge of T12 vertebra
While the right gastric artery, left gastric artery (LGA) and hepatic arteries (HA) are formed from the ventral splanchnic anastomosis, the dorsal splanchnic anastomosis forms the first branches of the gastrosplenic artery, pancreaticodudenal artery and colic artery [1,2,3]
We aimed to examine the variations of major arteries that play a role in nutrition of digestive organs such as stomach, liver and pancreas

Summary

Introduction

The aorta abdominalis (AA) is the continuation of the descending aorta after passing the midline diaphragm through the hiatus aorticus at the lower edge of T12 vertebra. AA gives branches from the ventral, lateral and dorsal aspects. Ventral branches are single and provide blood supply to the abdominal viscera [1,2]. From the 10th to 13th vitelline arteries that communicate between the aorta and a primitive ventral anastomotic artery. The regression of the ventral anastomosis and vitelline arteries (11th and 12th) and the persistent of the 10th and 13th roots provide giving origin to the coeliac trunk (CTR) and superior mesenteric artery (SMA). These branches emerge in a single form, extending towards the primitive digestive tract after the fusion of aortae dorsales during embryogenesis. While the right gastric artery, left gastric artery (LGA) and hepatic arteries (HA) are formed from the ventral splanchnic anastomosis, the dorsal splanchnic anastomosis forms the first branches of the gastrosplenic artery, pancreaticodudenal artery and colic artery [1,2,3]
