IntroductionProper identification of anatomic variations within the upper abdomen is essential for surgical and radiological interventions. A wide range of variations has been reported by Weiglein in 19961 . Pre-operative arterial imaging is of paramount importance to plan open and endovascular procedures involving the upper abdominal organs. 2-4 Volpe et al. 5 reported that injuries to hepatic arterial supply are more likely to be involved in pancreaticoduodenectomy, especially in the region of porta hepatis. The hepatic artery originates from the celiac axis in 52 to 76% of individuals, and the presence of variations of the normal hepatic artery anatomy is found in 32 to 48% of patients. 6-11 These variations may predispose patients to inadvertent injury during open surgical procedures or percutaneous interventions. The aim of this study was to describe the frequency and the anatomic course of variations of the normal hepatic artery circulation. Material and methodsThe present study included 84 male cadavers with height ranging between 158 to 167 cm and without apparent abnormalities. A midline transperitoneal incision was used to expose the supracolic compartment, and the supraceliac

“…In Japanese patients without PBM, the reported incidence of RHA being located in that position is about 10 % [26,27]. Weiglain reported that the incidence in Caucasian patients without PBM was 1.4 %, which was lower than that in Japanese patients [28]. Thus, the occurrence of "ventral RHA" in our patients with PBM was almost twice as frequent as that in the general Japanese population and higher than that in Caucasian population.…”

Anatomical variations of liver blood supply in patients with pancreaticobiliary maljunction

“…These vessels may be accessory, occurring in addition to the normal arterial supply, or replaced, representing the primary arterial supply to the lobe. Moreover, aberrant hepatic arteries can be of major surgical significance in operations of the upper intestinal tract, the liver, and the gallbladder and pancreas, especially for laparoscopic procedures [4][5][6][7][8]; they can also become a technical problem for infusion therapy and transarterial chemoembolization of neoplasms [9,10]. In Michels' classic autopsy series of 200 dissections [11], published in 1966, the basic anatomical variations in hepatic arterial supply were defined and this classification has served as the benchmark for all subsequent contributions in this area.…”

The aim of our study was to determine the frequency of different hepatic arterial variants identified on abdominal CT angiography (CTA) with a 64-row CT system and a high resolution protocol. A total of 250 consecutive abdominal CTAs performed on a 64-row CT system were evaluated. Two radiologists in consensus analyzed arterial phase images; the anatomical findings were grouped according to Michels' classification. An anomalous arterial pattern was observed in 34% of the cases. The most common anomaly was Michels type III (9.2%), followed by types II and V (5.2%), type VI (4.0%), types IV, VII, and IX (2.0%), and type VIII (0.6%). No cases of type X were detected. Unclassified variations were observed in 3.3% of the cases. The new generation of 64-row MDCT allows optimal visualization of splanchnic vascular anomalies with a minimally invasive examination. This visualization is extended to those vessels with a small caliber and slow flow resulting in difficult recognition by classic angiographic studies. The knowledge of anomalous arterial patterns could be very useful in the preoperative planning of surgical and interventional liver procedures.
