Abstract:
Objective To discuss the clinical significance of anomalous origination of right gastric artery in interventional treatment for hepatocellular carcinoma(HCC).Methods The dynamic enhanced CT scanning of the liver with a 64-slice spiral CT unit was performed in 72 HCC patients.In arterial phase,maximum intensity projection(MIP) and volume reconstruction technique(VRT) were used to observe the origin of the right gastric artery and its relationship with the hepatic artery.The findings were compared with the angiographic results.Results Of the total 72 cases,the anomalous origin of the right gastric artery was found in 43(59.8%).The anomalous origins of the right gastric artery included proper hepatic artery(n=19),left hepatic artery(n=17),gastroduodenal artery(n=4),right hepatic artery(n=2) and common hepatic artery(n=1).The results obtained from three-dimensional reconstruction were in good accordance with angiographic findings.Conclusion The anomalously originated right gastric artery most commonly originates from the left hepatic artery.Three-dimensional reconstruction obtained from the 64-slice spiral CT scans can provide the clear and reliable images of the right gastric artery,which is very helpful for the interventional procedure.
