Abstract Introduction Delineation of variant anatomy in celiac trunk and superior mesenteric artery including its origin and branching pattern and variations in branching pattern of hepatic artery in patients of hepatopancreaticobiliary malignancy with the use of mutidetector CT (computed tomography) angiograpgy was performed. Materials and Methods All CT examinations were performed on a 64-multidetector computed tomography (MDCT) scanner. Technical features of multislice computed tomography (MSCT) are as follows: 64 mm × 1 mm collimation, minimum slice thickness of 0.625, gantry rotation time of 320 ms, 120 kV, and 320 mAs. CT angiography was performed with intravenous (IV) administration of nonionic contrast material, that is, iodixanol (Visipaque). The contrast medium and saline solution were injected with a Medrad power injector at 3 mL/sec through an 18-gauge plastic intravenous catheter placed in an antecubital vein in most of the cases. Contrast medium volumes varied between 100 and 150 mL at 1.5 mL/kg. Images were obtained in triphasic pattern at arterial (20–30 seconds), portal (60–70 seconds), and equilibrium (at 3 minutes) phases. Results Five types of celiac axis anatomic variations and nine type of variants in celiac axis branching was found in the study sample of 124 patients. Classical celiac axis anatomy was seen in 92.7% of the cases, while the five types of variation in branching were found in nine patients. Majority of cases showed pattern I (59.6%) followed by patterns V (12.1%), II (9.7%), and III (8.9%). There were three (2.4%) cases each showing pattern VIII and AA, and two (1.6%) cases each showing patterns IV and VI, respectively. There was one (0.8%) case each showing pattern VII and IX. A total of three (2.4%) cases showed right hepatic artery arising from celiac axis. Conclusion We conclude that most common pattern of celiac axis and superior mesenteric artery (SMA) branching is classical pattern (92.7%) which is in concordance with literature. Type-I pattern of hepatic artery branching was most common (59.6%), similar to that documented in literature. Although the most common variation in our study is type V (12.1%), followed by types II (9.7%) and III (8.9%), the most common variation in most of the literature was found to be type III. CT angiography hence is an excellent diagnostic modality for depiction of arterial anatomic variations and provides a roadmap for surgical treatment.

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.

The Right

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.
