Cystic vein : As a perfusion vein of hepatic protion-angiographdcal study

Abstract

In order to determine the hepatic portions by cystic vein, we carried out abdominal angiography in 153 patients. The cystic vein was recognized in eleven patients, but only in nine cystic venous flow could be measured. In this group of patients, in which the cystic venous flow was detected, hepatic angiography was performed through the right hepatic artery (RHA) in six patients, the anterior branch of RHA in one patient, and the cystic artery in two patients.
Simultaneously, angiographical CT was performed in five patients. As the result, it is presumed that the cystic venous flow perfused segment 4 portal branch (P4) + segment 5 (S5) in four patients, P4 in two patients, segment 6 portal branch (P6), S5+right portal vein (RPV) + right hepatic vein (RHV), and S5 +RHV in one patient, respectively, and we concluded that in 70% of cases cystic venous flow perfused either P4 or S5.
