In this study, the significance of contrast-enhanced intraoperative ultrasonography (CEIOUS) images of HCC vasculature was evaluated by clinicopathological and gene expression analyses. We enrolled 82 patients who underwent curative hepatic resection for HCC with CEIOUS. Clinicopathological and gene expression analyses were performed according to CEIOUS vasculature patterns. CEIOUS images of HCC vasculatures were classified as reticular HCC or thunderbolt HCC. Thunderbolt HCC was significantly correlated with higher alpha-fetoprotein levels, tumor size, histological differentiation, portal vein invasion, and tumor-node-metastasis stage, and these patients demonstrated a significantly poorer prognosis for both recurrence-free survival (<\/jats:bold>\n                                 <jats:bold>\n                                    P\n                                 <\/jats:bold>\n                                 <jats:bold>= 0.0193) and overall survival (<\/jats:bold>\n                                 <jats:bold>\n                                    P\n                                 <\/jats:bold>\n                                 <jats:bold>= 0.0362) compared with patients who had reticular HCC.
