The Unusual Localization of Right Hepatic Artery Multiple Anatomic Variants in Celiac Axis
Electronic Journal of General Medicine
The extrahepatic vascular and biliary anatomy of Calot's triangle is well known to be highly variable and this provides a surgical challenge. The liver has a dual blood supply consisting of the portal vein and the hepatic artery. The hepatic artery which delivers 25% of the blood supply, arises from the celiac trunk. The celiac trunk gives off the left gastric, splenic and common hepatic arteries. The common hepatic artery then divides into gastroduodenal artery and hepatic artery proper which diverts in right and left hepatic arteries. The systic artery usually originates from the right hepatic artery. The "classic" arterial anatomy is present in approximately 75% of cases. The remaining 25% of the cases have many anatomical variants. Here in we present a patient with multiple anatomic variants in celiac trunk which were determined incidentally during laparoscopic cholecystectomy. Being aware of the arterial variations in the liver is really important in surgical procedures in order to avoid bleeding and ischemia.
Variation in the branching pattern of celiac trunk A case report
Journal of Morphological Sciences, 2015
Arterial 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, gast...
Rare variations in the Origin, Branching Pattern and Course of the Celiac Trunk: Report of Two Cases
The Malaysian journal of medical sciences : MJMS, 2016
Multiple anomalies in the celiac arterial system presents as rare vascular malformations, depicting deviations of the normal vascular developmental pattern. We found a common left gastro-phrenic trunk and a hepato-spleno-mesenteric trunk arising separately from the abdominal aorta in one cadaver. We also found a common hepatic artery and a gastro-splenic trunk arising individually from the abdominal aorta in another cadaver. Even though many variations in the celiac trunk have been described earlier, the complex variations described here are not mentioned and classified by earlier literature. Knowledge of such variations has significance in the surgical and invasive arterial radiological procedures in the upper abdomen.
Accessory Hepatic Artery Arising from Celiac Trunk: An Incidence in a Thai Cadaver
International Journal of Morphology, 2014
An exhaustive knowledge of the liver vascular patterns as well as possible anatomical variations is significant in the planning and performance of all liver surgical procedures in order for the vascularity not to be disturbed or not causing necrosis of the liver parenchyma postoperatively. The celiac trunk usually provides three branches; left gastric, splenic and common hepatic arteries. The left and right hepatic arteries generally derive from proper hepatic artery which is a branch of common hepatic artery. To study the incidence of celiac trunk ramification, the branching patterns of the celiac trunk of 23 Thai cadavers (17 males, 6 females) were documented during routine dissection by medical students at the
Anatomical variations of the hepatic portal vein associated with incomplete celiac trunk
Romanian journal of morphology and embryology = Revue roumaine de morphologie et embryologie, 2011
An association of two anatomical variations was revealed in a 65-year-old male cadaver: the first variation concerns the forming of the trunk of the hepatic portal vein, while the second concerns the branches of the celiac trunk. In this case, the inferior and superior mesenteric veins form a common trunk that is further united with the splenic vein and gives rise to the hepatic portal vein. At the same time, the existence of an incomplete (branched) celiac trunk was revealed, the hepatosplenic trunk from which the common hepatic artery and the splenic artery arise; the left gastric artery arises separately at 0.5 cm superolaterally from the origin of the celiac trunk. Familiarity with this anatomical variation provides useful information for abdominal surgery procedures.
Novel anatomic variation: heptafurcation of the celiac trunk
Surgical and Radiologic Anatomy, 2018
We report here anatomic variants which were found during a retrospective study of a male patient, 54 years old, evaluated in computed tomography: heptafurcation of the celiac trunk (CT) and bilateral double renal arteries. The seven branches of the heptafurcated CT were the (1) left and (2) right inferior phrenic arteries, the (3) splenic and (4) left gastric artery, the (5) common hepatic artery, further sending off the (a) proper, continued as left, hepatic artery and (b) the gastroduodenal artery, (6) a replaced right hepatic artery and (7) the dorsal pancreatic artery. To our knowledge, heptafurcation of the CT was not reported previously. The arterial variants have great importance during various surgical and interventional procedures and should be documented prior to respective procedures.

To describe the main anatomical variations of the celiac trunk and the hepatic artery at their origins. This was a prospective analysis of 100 consecutive computed tomography angiography studies of the abdomen performed during a one-year period. The findings were stratified according to classification systems devised by Sureka et al. and Michels. The celiac trunk was "normal" (i.e., the hepatogastrosplenic trunk and superior mesenteric artery originating separately from the abdominal aorta) in 43 patients. In our sample, we identified four types of variations of the celiac trunk. Regarding the hepatic artery, a normal anatomical pattern (i.e., the proper hepatic artery being a continuation of the common hepatic artery and bifurcating into the right and left hepatic arteries) was seen in 82 patients. We observed six types of variations of the hepatic artery. We found rates of variations of the hepatic artery that are different from those reported in the literature. Our find...

Understanding of variations in the course and source of abdominal arteries is crucial for any surgical intervention in the peritoneal space. Intricate surgeries of the upper abdominal region, such as hepato-biliary, pancreatic, gastric and splenic surgeries, require precise knowledge of regular anatomy and different variations related to celiac trunk and hepatic artery. In addition, information about the origin of inferior phrenic artery is important in conditions such as hepatocellular carcinoma and gastroesophageal bleeding management. The present study gives an account of anatomical variations in origin and branching pattern of celiac trunk and hepatic artery by the use of CT (computed tomographic) angiography. The study was performed on 110 (66 females and 44 males) patients in a north Indian population. Results unraveled the most common celiac trunk variation as hepatosplenic trunk with left gastric artery, which was observed in 60% of cases, more common in females than in male...

The knowledge of vascular variations, like other anatomical variations, is important during the operative, diagnostic and endovascular procedures in abdomen. This report describes variations in the celiac trunk and abnormal entry of hepatic arteries into the liver as found during routine dissection in approximately 65 years old female cadaver. The celiac trunk was two inches long and gave 2 inferior phrenic arteries, a left gastric artery, and then bifurcated into a splenic and a common hepatic artery. The common hepatic artery gave rise to left hepatic artery, which entered the liver through fi ssure for ligamentum venosum. The common hepatic artery then divided into right hepatic and gastroduodenal arteries. The cystic artery was a branch of the left hepatic artery. The porta hepatis of the liver was situated on the right side of the caudate lobe. The knowledge of variation reported here is important during endovascular procedures, cholecystectomy and liver transplantation from the living donors (Fig. 2, Ref. 18).
