Abstract: Objective To investigate the application value of 3D (three-dimensional) reconstruction of rotational digital subtraction angiography (DSA) in interventional treatment for hepatocellular carcinoma (HCC). Methods One hundred and four patients with HCC treated by interventional therapy in our hospital were selected, they were divided into 3D group (3D reconstruction by rotational DSA) and conventional group (conventional DSA) according to different examination methods. The display effect on lesions and the surgical effect of the two examination methods were retrospectively analyzed. Results Compared with the conventional group, the lipiodol deposition rate and the success rate of superselective arterial catheterization in the 3D group were higher (96.30% vs 72.00%, 94.44% vs 76.00%). The operation time of 3D group was shorter [(32.62±5.42) min vs (44.24±6.53) min], P<0.05. There was no significant difference in the amount of arterial contrast agent and the display rate of tumor blood supply arteries between the two groups (P>0.05). Compared with the conventional group, the first film rate (92.59% vs 68.00%) and the detection rate of hepatic artery grade 3/4 (96.30% vs 6.00%) in the 3D group were higher. The display rate of tumor collateral circulation (50.00% vs 24.00%), small lesions (25.93% vs 6.00%), blood supply artery of small lesions (25.93% vs 6.00%) and collateral circulation of small lesions (31.48% vs 0) in the 3D group were higher than those of the conventional group. The differences were all statistically significant (P<0.05). The total remission rate of 3D group was 70.37%, which was significantly higher than that of conventional group (44.00%, P<0.05). Conclusion In the interventional treatment of liver cancer, 3D reconstruction technology of rotational DSA can improve the image quality, shorten the operation time and improve the operation effect.
