Dec 5, 2020 · Laparoscopic gastric banding comprises the systematic section of the pars flaccida and condensa of the lesser omentum. Comprising a denser cranial portion and a more flexible caudal portion, termed the pars flaccida, the hepatogastric ligament has distinct sections that serve specific functions. The next two most common variants consist of the replaced or accessory origins of the right and left hepatic arteries. Sep 21, 2022 · CHA: Common Hepatic Artery, SMA: Superior Mesenteric Artery, SA: Splenic Artery, LGA: Left Gastric Artery - (note the white outline showing the artery’s close proximity to the pancreatic head and coursing behind the pancreas, which is the more common presentation of this replaced vasculature). It plays a critical role in separating the greater and lesser sacs on the right side, crucial for the compartmentalization within the abdominal cavity. The CHA gives origin to the proper hepatic artery, which bifurcates into the right and left hepatic arteries (RHA and LHA) [3]. It is sometimes cut during surgery in order to access the lesser sac. We report an aberrant right hepatic artery coursing retroportally, with an aberrant left hepatic artery orig … Dec 10, 2023 · The replaced left hepatic artery serves a crucial role in the blood supply to the liver. Nov 1, 2023 · Due to its anatomic location, left replaced hepatic arteries are less frequently involved by pancreatic head cancers, but might be inadvertently injured during dissection of the gastrohepatic ligament and the pars flaccida during a Whipple procedure. Abstract: Purpose: Knowledge of hepatic arterial variations is important for surgeons and interventional radiologists in various hepatic interventions, not only for appropriate planning but also to prevent complications. Gruttadauria S, Foglieni CS, Doria C, Luca A, Lauro A It contains the right and the left gastric arteries. In the abdominal cavity, it separates the greater and lesser sacs on the right. Normal liver vascularization pattern is reported in 50–80 % of cases [1, 9, 17, 23]. Interestingly, this “conventional” hepatic vasculature is only seen in up to three-quarters of the public [2]. [4] Lastly, the proper hepatic artery bifurcates into the right and left hepatic artery which supply their respective lobes of the liver, while the right hepatic artery supplies the gallbladder via the cystic artery [1]. However, in 40% of cases, anomalies can exist. Aberrant left hepatic artery arising from the left gastric artery and liver function after radical gastrectomy for gastric cancer. Although variations in its origin and course are common, it typically supplies blood to segments of the left lobe of the liver. . Aberrant left hepatic arteries (ALHA) originating from the left gastric artery are located in the pars condensa of the lesser omentum. Classic branching of the common hepatic artery from the celiac artery, and the proper hepatic artery into right and left hepatic arteries to supply the entire liver, is seen in 55 Jan 31, 2017 · In ∼60% of cases, hepatic artery anatomy is of the normal variant. The aim of the present work was to study aberr … Aug 22, 2025 · Gross anatomy The proper hepatic artery bifurcates into the left and right hepatic arteries at or before reaching the porta hepatis. Incidence of hepatic arterial variations is high, however replaced left hepatic artery is a rare variant. These are end arteries and supply the left and the right halves of the liver respectively. The significance of the variant left accessory hepatic artery in surgery for proximal gastric cancer. Oct 6, 2016 · The proper hepatic artery then continues its course toward the hilum of the liver before bifurcating into the right and left hepatic arteries within the hilar plate. Jan 1, 2010 · Okano S, Sawai K, Taniguchi H, Takahashi T. Lurie AS. The hepatogastric ligament consists of a dense cranial portion and the caudal portion termed the pars flaccida. Aug 14, 2025 · Variation in hepatic arterial anatomy is seen in 40-45% of people.
