Title: Evaluation of hepatocellular carcinoma supplied by the left gastric artery with dual-source CT angiography
Abstract: Objective:To investigate the incidence and influential factors of hepatocellular carcinoma(HCC) supplied by the left gastric artery.Methods:91 patients with HCC in left lobe were prospectively included in the study.Standardized dual-source CT(DSCT) multi-phases acquisition was performed for all patients.Thin slice source images were reconstructed using techniques of multi-planar reconstruction,curved planar reconstruction,maximum intensity projection and volume rendering to display the left gastric artery.The images were interpreted by three experienced abdominal radiologists.The incidence of HCC fed by LGA and factors like the size,location,pseudocapsule of HCC lesions and previous history of transarterial chemoembolization(TACE) therapy were analyzed.Results:There were 23(22.1%) cases supplied by LGA in 91 patients with a total of 104 HCC lesions,while 19 lesions were type macro-mass compared with 4 lesions as type nodus,22 lesions invaded Glisson capsule and 17 lesions had previous history of TACE therapy.All lesions had no unbroken pseudocapsule.LGA participated in HCC blood supply by left lobe hepatic artery(n=3) and accessory left lobe hepatic artery(n=5) originated from LGA,as well as branch direct supplying the lesions(n=15).Conclusion:LGA is common extrahepatic collateral artery of left lobe HCC and the presence is significantly correlated with the tumor size,the location,the status of pseudocapsule and history of TACE therapy of HCC lesion.
