Abstract
[한글]
[영문] The variations in origin and course of the common hepatic artery and its branches were observed in 140 Korean adult cadavers. The common hepatic artery arose from the celiac trunk in 93.6% of cases. In almost all instances this artery coursed to the left of the common bile duct. A replacing common hepatic artery was derived from the superior mesenteric artery. It was absent in 5.7% of cases. A normal right hepatic artery was present in 93.6% of the cases. A replacing right hepatic artery frequently arose directly from the celiac trunk and superior mesenteric artery. The location and course of the right hepatic artery are subject to considerable variations. In 82.2% the artery crossed from left to right, posterior to the common hepatic duct. All replacing-right hepatic arteries have a characteristic course that passed poseterior to the portal vein and common hepatic duct. A normal left hepatic artery was present in 93.6% of the cases. A replacing type of left hepatic artery occurred in 6.4% of the cases. In 5% this artery asose directly from the celiac trunk. An accessory left hepatic artery was encountered with and incidence of 18.8% and all arose from the left gastric artery. A right gastric artery is the most variable branch of the common hepatic artery in origin. Most freqeuntly it arose from the proper hepatic artery (45.7%) and next in order of frequency from left hepatic, common hapatic and gastroduodenal arteries. A gastroduodenal artery arose from the mornal common hepatic artery in 91.4% of cases. A replacing type of gastroduodenal artery was commonly derived from the left hepatic artery (5.7%). The gastroduodenal artery in relation to the common bile duct mostly lie the left of the ductal system and reaching the supraduodenal or retroduodenal portion, this artery crossed the anterior to the duct. There were 163 cystic arterise in 140 speciments. The cystic artery arose from the right hepatic artery in 87.7% of total number of arteries and in 52.7% arising in the Calot's cystic triangle. The replacing types of the cystic arteryderived from the replacing right hepatic artery and the proper hepatic artery were 4.8% and 3.3% respectively. The cystic artery, which arose outside of Calot's triangle, more frequently passed the anterior to the comon hepatic duct than the posterior. Doubling of the cystic artery occurred in 16.4% of the cases. These dual cystic arterial branches were most commonly derived from right hepatic artery. In this study it was not found that a specimen had three cystic arteries or cystic artery was lack.
