Introduction:Each hepatic artery is functionally essential for providing blood supply to the liver, and so are variant arteries. Variant arteries, including the accessory right hepatic artery (ARHA) and replaced right hepatic artery (RRHA) are commonly described in the literature. However, they usually occur independently. Here, we report an extremely rare case that involved both an ARHA and an RRHA arising from the gastroduodenal artery (GDA) and superior mesenteric artery (SMA), respectively. To date, this situation has never been reported in the literature.They were preoperatively identified during magnetic resonance imaging (MRI) examination in a 69-year-old male patient with hepatocellular carcinoma. And they were further verified by following conventional angiography for transcatheter arterial chemoembolization (TACE) for the patient. In addition, the patient's tumor was primarily supplied by these 2 variant arteries. After the successful TACE procedure, the patient had a well postoperative recovery.Conclusions:By analyzing this case and performing a systematic review of the literature, the important clinical implications of the ARHA and RRHA will be investigated and discussed. Main lessons learned from this case thorough understanding of the normal anatomy of the hepatic artery and its anatomic variation is crucial for surgeons and interventional radiologists; preoperative computed tomography, MRI, and intraoperative angiography play an important role in detecting the variant hepatic artery; identifying these anomalous hepatic arteries before operation can effectively avoid unintentional injury during surgery, such as massive hemorrhage or hepatic infarction.

“…An accessory right hepatic artery (aRHA) refers to an additional artery of the right liver, while a normal branch derives from a proper hepatic artery (PHA) [ 3 ]. In general, aRHA arises mainly from the superior mesenteric artery (SMA), but may also branch off from the celiac trunk (CT), common hepatic artery (CHA), renal artery (RA), gastroduodenal artery (GDA), abdominal aorta (AA), and others.…”

Purpose During the last decades, it has been established that there are numerous individual anatomical variations of the arterial blood supply in human liver. In the present study, we examined the liver vascularization of an intrahepatic cholangiocarcinoma patient. Methods For surgical planning, an enhanced CT scan was performed and a three-dimensional model of liver vascularization constructed. Results The patient was diagnosed as a Michel’s type VII hepatic artery variation. An accessory right hepatic artery arose from the superior mesenteric artery and had distributed into the right anterior liver to provide the blood supply of segments V and VIII, which was more medial than the territory of the right hepatic artery coming from the proper hepatic artery. At the same time, an accessory left hepatic artery originated from the left gastric artery. Conclusion We present a case in which an accessory right hepatic artery provided a territory more medial than a right hepatic artery coming from the proper right artery.

Bianchi et al (2014), Rachanee Chanasong (2014), Dandekar et al (2015), Yan et al (2015), Durand-López (2016) and Alghamdi et al (2017) found: Arterial irrigation comes from the hepatic artery proper in 70 % of cases; from the hepatic artery proper and a branch of left gastric artery (A12.2.12.013) in 25 %, from the hepatic artery proper plus a branch from left gastric artery plus a branch from superior mesenteric artery (A12.2.12.053) in 3 %, and from the hepatic artery proper and a branch from superior mesenteric artery in 2 %. The hepatic artery proper is divided into left and right branches; the left branch is short and less voluminous than the right branch.…”

Due to a lack of consensus on the description of the human liver anatomy, we decided to explore different researches worldwide. Studies are focused on the hepatic vascularization. The results obtained through serial dissections in embryos, fetuses and adults have contributed to new definitions. Researchers around the world have agreed on finding the bases to propose a liver segmentation with seven portal segments.
