“…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.

“…). Because of these different configurations, the splenic artery with an intact DPA is the most important artery in preserving adequate blood supply to the pancreas tail as stated by Van Damme . The DPA, as mentioned above, originates from the SA in 42%–44% of the cases and this occurs in the first third proximal portion.…”

“…In a meta-analysis of CA variations which included 12,000 cases from 36 studies, there was no mention of a replaced GDA (rGDA) [2,7]. Many other studies have identified frequency of variations in origin of rGDA, summarised in Table 1 [14][15][16][17][18][19][20][21][22][23][24][25][26]. The various sites of origin of rGDA are shown in Figure 1.…”

Gastroduodenal artery: single key for many locks

Gastroduodenal artery (GDA) commonly arises from common hepatic artery, a branch of celiac axis. It holds a unique anatomical position that connects the foregut and midgut due to its intimate communications with foregut and midgut arterial supply. Its numerous anatomical variations have a significant impact on planning and performance of hepatopancreaticobiliary (HPB) surgery. Its close relation to the first part of duodenum, common bile duct and head of pancreas makes it susceptible for inadvertent bleeding during or after surgery, or due to various HPB pathologies. Also, a large number of vascular interventions rely on GDA and its branches. Careful preoperative planning is the key and a detailed knowledge and awareness of its variant anatomy is of paramount importance, be it liver resections, liver transplant, biliary and pancreatic resections and pancreatic transplant or transarterial procedures involving these arteries. GDA can also be a cause of gastrointestinal hemorrhage due to true or pseudoaneurysms and anatomy has significant implications on its management. The article provides a succinct review on relevance of GDA anatomy and variations and highlights that preoperative planning and intraoperative awareness of variations is the key to performance of safe HPB surgery and interventions.
