Purpose: To determine the distribution of the types of variations in the portal vein and vena cava inferior and its branches using advanced image processing techniques in contrast enhanced abdominal multislice computed tomography (MSCT) examinations. Methods: The study included 471 patients, comprising 254 males (53.9%) and 217 females (46.1%) with a median age of 53.7 ± 16.1 years, who underwent abdominal MSCT between April 2011 and December 2017. Results: Of 471 patients, 2 patients (0.4%) had variation of the inferior vena cava, 122 patients (25.9 %) had variation of the hepatic vein, 162 patients (34.4%) had variation of the renal vein and 138 patients (29.3%) had variation of the portal vein. Conclusion: It is of great importance to use MSCT prior to surgical procedures such as transplantation, in which vascular variations are predetermined, and to pay attention to variations during reporting of the examination.
