“…To the best of our knowledge, our study is the first to perform statistical comparison in a mixed sample selected under the same criteria and prove this assumption correct. Finally, few studies [36,72,92] have stated that existence of anatomic variation could alter a vessels' morphometry. We have chosen to discard cadavers presenting variations interfering with results of this study.…”

“…Whether or not existence of anatomic variation is beneficial is controversial. Some authors [84] believe that variations existence is related to smaller diameter and thus less satisfactory results and more complications while others [36] support the opposite. Detailed common hepatic artery morphometry knowledge is necessary for generation of flow models, critical for chemoembolisation procedures and microspheres design [5].…”

“…Stent grafts design and placement for endovascular repair of AA and branches aneurysms [38,40], chemoembolisation for haemorrhage or chemotherapy [5], visceral aneurysm diagnosis and treatment [8] and transplantation [36,87] are based on precise calculation of AA branches' diameters. Diagnosis, staging and treatment of many relative common diseases including chronic mesenteric ischaemia or other occlusive diseases of AA branches [25] and chronic renal insufficiency [3] utilise such measurements.…”

“…The arteries leading to the liver should be conscientiously studied during the liver removal process by the donor, aiming at avoidance of causing injuries and inadequate perfusion of the liver in the recipient. This finding has received great attention from researchers in recent years, since the profile of liver perfusion is obviously of great importance [4]. Therefore, the profound knowledge of the location of all the arteries is essential.…”

Abstract:The knowledge of liver blood vessels anatomy is essential for hepatic transplants and hepatobiliary and pancreatic procedures. In addition, it is crucial to be aware of the liver anatomy due to its importance in the operations of the hepatic neoplasms. Studies have shown that hepatic perfusion presents a number of variants, which have an important role in liver physiology as well as in the treatment of hepatoblastic neoplasms. The purpose of the present work is the presentation and analysis of anatomic variations and anomalies of the hepatic artery, and the importance and application of this knowledge in clinical practice of liver diseases. In particular, the significance of this insight into hepatoblastic neoplasms is presented.

“…Vascular complications after liver transplantation are often associated with poor outcomes for both the grafts and patients (Tzakis, 1985). The anatomical variation of hepatic artery in the liver transplanted recipients increased the risk of hepatic artery complications after transplantation (Ishigami et al, 2004). The variation of celiac axis and common hepatic artery had been studied in 5002 Korean patients.…”

Accessory Hepatic Artery Arising from Celiac Trunk: An Incidence in a Thai Cadaver

SUMMARY: An exhaustive knowledge of the liver vascular patterns as well as possible anatomical variations is significant in the planning and performance of all liver surgical procedures in order for the vascularity not to be disturbed or not causing necrosis of the liver parenchyma postoperatively. The celiac trunk usually provides three branches; left gastric, splenic and common hepatic arteries. The left and right hepatic arteries generally derive from proper hepatic artery which is a branch of common hepatic artery. To study the incidence of celiac trunk ramification, the branching patterns of the celiac trunk of 23 Thai cadavers (17 males, 6 females) were documented during routine dissection by medical students at the Department of Anatomy, Faculty of Medical Science, Naresuan University, Thailand. The clinically important variations of the celiac trunk were noted. The results showed that all celiac trunks arose from each aortas at the T12 vertebra (17.39%, 4 cases), intervertebral disc between T12 and L1 vertebra (78.26%, 18 cases) and upper 1/3 rd of L1 vertebra (4.35%, 1 case). We found 95.65% (22 cases) normal celiac trunk trifurcation; whereas, 4.35% (1 case) was abnormal quadrifurcation of the trunk. The accessory hepatic artery (aHA) was presented as an additional branch of celiac trunk because the conventional pattern of the left and right hepatic arteries was presented. This finding is one of the rare anatomical variations which is reported in available literatures. The awareness of celiac trunk and its stems aberrant is important in procedures such as liver transplant for appropriate vascular ligation and anastomosis.

Does Variant Hepatic Artery Anatomy in a Liver Transplant Recipient Increase the Risk of Hepatic Artery Complications After Transplantation?

Abstract: Variant hepatic artery anatomy in a liver transplant recipient increased the risk of hepatic artery complications after transplantation. The smaller caliber of the native common hepatic artery may contribute to the higher risk.
