Abstract Objective: To analyze the prevalence of anatomical variations of celiac arterial trunk (CAT) branches and hepatic arterial system (HAS), as well as the CAT diameter, length and distance to the superior mesenteric artery. Materials and Methods: Retrospective, cross-sectional and predominantly descriptive study based on the analysis of multidetector computed tomography images of 60 patients. Results: The celiac trunk anatomy was normal in 90% of cases. Hepatosplenic trunk was found in 8.3% of patients, and hepatogastric trunk in 1.7%. Variation of the HAS was observed in 21.7% of cases, including anomalous location of the right hepatic artery in 8.3% of cases, and of the left hepatic artery, in 5%. Also, cases of joint relocation of right and left hepatic arteries, and trifurcation of the proper hepatic artery were observed, respectively, in 3 (5%) and 2 (3.3%) patients. Mean length and caliber of the CAT were 2.3 cm and 0.8 cm, respectively. Mean distance between CAT and superior mesenteric artery was 1.2 cm (standard deviation = 4.08). A significant correlation was observed between CAT diameter and length, and CAT diameter and distance to superior mesenteric artery. Conclusion: The pattern of CAT variations and diameter corroborate the majority of the literature data. However, this does not happen in relation to the HAS.

Abstract Although digital angiography remains as the gold standard for imaging the celiac arterial trunk and hepatic arteries, multidetector computed tomography in association with digital images processing by software resources represents a useful tool particularly attractive for its non invasiveness. Knowledge of normal anatomy as well as of its variations is helpful in images interpretation and to address surgical planning on a case-by-case basis. The present essay illustrates several types of anatomical variations of celiac trunk, hepatic artery and its main branches, by means of digitally reconstructed computed tomography images, correlating their prevalence in the population with surgical implications.

The arterial supply of the gallbladder usually arises from the right hepatic artery. Other origins include the left, proper, and common hepatic arteries. We report cases of the cystic artery arising from the superior mesenteric artery and arising from the dorsal pancreatic artery originating in turn from the superior mesenteric artery, as demonstrated by angiography and computed tomography.

Introduction: In a setting of living-donor liver transplant and patients undergoing extended hepatic resections for both primary and metastatic liver tumors, preoperative assessment of hepatic arterial anatomy is very important because of the risk of ischemic complications in the event of inadvertent injury to the arterial supply. Anatomical variations in hepatic arterial supply to the liver are very common and seen in nearly half the population. Identifying anomalous origin of segment 4 hepatic artery is vital since this vessel can cross the transection plane and can result in liver ischemia and liver failure. The purpose of our study is to study the variations in hepatic arterial anatomy to segment 4 of the liver in the Indian population. Materials and Methods: A retrospective evaluation of 637 consecutive computed tomography (CT) angiograms over a period of 1 year was performed, and we analyzed the arterial supply to segment 4 of the liver. Results: We found that the arterial supply to segment 4 of the liver originated from left hepatic artery (LHA) in majority of cases, 76.3%. LHA along with the accessory LHA supplied this segment in 6.4%, whereas the accessory LHA solely supplied this segment in 0.4%. The right hepatic artery (RHA) was seen to supply this segment in 10.2%. Dual supply with branches from the RHA and LHA was seen in 6.6% of patients. Conclusion: Preoperative mapping of segment 4 hepatic arterial supply using CT angiography will act as a roadmap to surgeons as they attempt to carefully dissect and preserve this segments' arterial supply. Depending on the anatomical variation, surgical techniques will vary to ensure safety of segment 4 arterial supply.

AbstractArterial supply for the derivatives of foregut in the abdomen is provided by the branches of the celiac trunk. Celiac trunk is the first ventral branch of abdominal aorta and usually branches into splenic, common hepatic and left gastric arteries. Variations in the branching pattern of celiac trunk are common but in most of the people, they remain asymptomatic and go unnoticed. A good knowledge of these anatomical variations is important for surgeons undertaking various surgeries in the abdominal region and will help to minimise the complications related to abdominal surgery. Clinicians and radiologists should also be aware of any variations in the vascular pattern of the celiac trunk before performing angiographic examinations. In the current case, the celiac trunk divided into two branches; left gastric artery and hepato-splenic trunk. The hepato-splenic trunk further divided into splenic and common hepatic arteries. The common hepatic artery trifitrcated into proper hepatic, gastroduodenal and accessory hepatic arteries. Hepatic artery proper divided into right and left hepatic arteries. The accessory hepatic artery was tortuous and was as large as the left hepatic artery. It gave origin to the right gastric artery and entered the liver through left end of porta hepatis.

Background: The abdominal aorta and its main branches, such as the celiac trunk and the renal arteries are manipulated during various radiologic, surgical, and oncologic procedures. This study aimed at evaluating the anatomical pattern of these vessels to assist surgeons and radiologists reduce the risk of intra- as well as postoperative complications. Methods: A retrospective analysis of 536 Computed Tomography Angiography (CTA) studies of living potential kidney donors was conducted from January 2012 to December 2018. Results: The anatomical variations of the celiac trunk was found in 9.5% of the cases. Among these cases, the most frequent variation was the Left Gastric Artery (LGA) as the first branch of the celiac trunk (80.4% of the cases). Gender was not overall significantly associated with the variations of the celiac trunk (P=0.670); however, there was a significant correlation between male gender and the most prevalent form of the celiac trunk variation (P=0.004). Variations of the renal artery occurred in 22.94% of the cases, with the left accessory renal artery being the most common variant (28.45% of the cases). Gender and the involved side (right/left) were not significantly related to the renal artery variations (P=1.000 & P=0.546, respectively). No concomitant variation of the celiac trunk and the renal artery was detected in our study. Conclusion: The anatomical variations of the celiac trunk and the renal arteries occur commonly; thus, the branching pattern of these arteries should be assessed prior to any procedure concerning them.
