초록/요약
Purpose : To retrospectively assess the incidence, the variation of accessory hepatic vein (AHV), and to determine the predictable factor for AHV by using multi detector row computed tomography (MDCT) Materials and Methods : Three hundred sixty patients (185 men, 175 women, average age: 52.1 years) who underwent MDCT were included in the study group . All patients did not have cirrhotic configuration or space occupying lesion in liver. Two radiologists reviewed all CT scans and measured the diameter of middle hepatic vein (MHV) and right hepatic vein (RHV) by consensus. The MHV/RHV diameter ratio in patients with AHV was compared to that in patients without AHV. Student's t-test was performed to identify significant difference between the two groups. Result : The incidence of AHV is 45.5% (164/360). Most of AHV was located in inferoposterior segment of right lobe of liver. The branching patterns of the AHV into IVC are a liner draining type, V-shaped draining type, parallel draining type. The incidence of those was 58.5%, 20.7%, and 20.7%, respectively. The mean of MHV/RHV diameter ratio in patient with AHV is significantly higher than that of MHV/RHV diameter ratio in patient without AHV (1.080.28, 0.810.19, respectively). There are significant difference in two groups (p<0.001). Conclusion : AHV showed relatively high incidence (45.5%). There were several variations which drained into IVC from AHV. If RHV is thinner than MHV, there is more possibility that accessory hepatic vein exists.
