Abstract

Background and aim: To investigate the prevalence, anatomy and distribution of the hepatic falciform artery (HFA) and Sappey’s superior artery (SSA) using C-arm CT hepatic arteriography (C-arm CTHA). Materials and methods: From January 2011 to December 2012, 220 patients who underwent C-arm CTHA during initial transarterial treatment for hepatocellular carcinoma were included in this retrospective study. The HFAs and SSAs prevalence and origin were evaluated using axial images of C-arm CTHA. A 5-point scale for HFAs and a 4-point scale for SSAs were used to designate the radiologically conspicuous arteries. Results: The prevalences of the total HFAs and SSAs were 95 % (n=209) and 22 % (n=49), while those of radiologically conspicuous HFAs and SSAs were 62 % (n=137) and 10 % (n=22), respectively. Thirty HFAs (22 % of radiologically conspicuous HFAs and 14 % of the total study population) were distributed in the subcutaneous layer of the anterior abdominal wall, while the majority of SSAs ran through the superior part of the falciform ligament in the left-anterior direction and anastomosed with left inferior phrenic artery. Conclusion: Our study using C-arm CTHA revealed that the prevalence of the HFA is higher than the existing knowledge and proved the existence of the SSA radiologically for the first time. Key Points: • Prevalence of hepatic falciform artery is 95 %, higher than previously known. • 22%of conspicious hepatic falciform arteries distributed in subcutaneous tissue around umbilicus. • The existence of Sappey’s superior artery was proved with a radiological method.
