Abstract Hepatobiliary surgery through laparoscopic approach is becoming a routine. Knowledge of extrahepatic arterial tree is essential for surgical and imaging procedures. Anatomical complexity is expected since the liver is developed by mergingof lobules with its separate blood supply. This makes a wide range of variations in the pattern of vascular arrangement and so reinforces the need for an accurate understanding of full spectrum of variations. This study aimed to investigate the variations in origin and distribution of extrahepatic arterial supply. Fifty volunteers (32 males and 18 females) aged 20–70 years were randomly recruited from the department of CT scan in Al Amal Hospital, Khartoum North, Sudan. The patients were already candidates for CT angiography with contrast for conditions other than hepatobiliary diseases. The reported data is related to those who accepted to participate in the study. Patients with history of hepatobiliary disease were excluded. 3D views of the scans were treated and the extrahepatic arterial tree was traced in a computer-based software. Key findings suggest that Michel's classification was considered the standard template for description – 76% of them showed Michel's type I classification. Types III and V constituted about 2%. About 4% of the cases were represented by types VI and IX. Other types of variations constituted about 12%. To conclude, although type I classification which describes the textbook pattern of hepatic artery distribution was significantly detected among the Sudanese population, other variants were to be considered since they are related to major arteries like aorta and superior mesenteric. |
