Classification of the variant hepatic arterial pattern among patients in northern Nigeria (Case study of Hausa ethnic group of Kano State)

Abstract

The coeliac trunk is a wide ventral branch of abdominal aorta measuring about 1.25 cm in length and arising just below the aortic hiatus opposite the lower border of T12. The study investigated the classification of the variant hepatic arterial pattern among patients in northern Nigeria with particular focus on Hausa ethnic group of Kano State. The primary objective of the study was to classify hepatic arterial among adults in Kano state, Nigeria, by using three-dimension multidetector computerized tomography. The data utilized were obtained from the record unit of Radiology Department, Aminu Kano Teaching Hospital and ninety–three patients were used for the hepatic arterial classification. The result showed that the Michel’s classification of type I known as Normal had the highest percentage of 58.1%, followed by the type II, 12.9% and the least was type VII with 2.2%. The Hiatt’s classification, in this study also showed that the type I had the highest percentage of 58.1%, follow by the type II, (24.7%) and the least was type VI with 2.2% respectively. The determination of anatomical variations of the hepatic arteries among Hausa ethnic group of Kano state are of utmost importance for various surgical and radiological procedures to prevent any complications especially in liver transplantation.
