Abstract
Aim: To determine the additional value of computed tomography in the evaluation of vascular patterns of hepatocellular carcinoma (HCC).
Materials and methods: A cross - sectional study was conducted on 63 HCC patients who underwent transarterial chemoembolization at Hue University of Medicine and Pharmacy Hospital from 9/2018 to 10/2020. Vascular patterns of HCC were documented on CT and correlated with digital subtraction angiography (DSA). Diagnosis and management of HCC were based on the practice guideline of EASL 2018.
Results: The mean age was 63.2 ± 11.3 years, the average HCC diameter was 5.7 ± 3.4 cm, (range 1 - 14,5 cm). Vascular patterns of HCC at CT and DSA were hyperattenuating/tumor staining (87.3% vs. 96.8%), hypervascularity (58.7% vs. 88.9%), neovascularity (65.1% vs. 88.9%), arterioportal shunt (6.4% vs. 6.4%), extrahepatic parasitic supplies (25.4% vs. 19%), and anatomical variations (14.3% vs. 15.9%), respectively. There was a low agreement between CT and DSA on hyper and neovascularity. CT had high
sensitivity and specificity in detecting arterioportal shunt, extrahepatic supply and anatomical variations. Tumor size had a positive correlation with hypervascularity and was a predictor of hyper/neovascularity, arterioportal shunt, and extrahepatic supply.
Conclusion: CT had high sensitivity and specificity in detecting arterioportal shunt, extrahepatic supply and anatomical variations. Careful and comprehensive interpretation of preprocedural computed tomography and angiography is essential to optimize treatment and patient outcomes.
