Three-dimensional DSA guidance reduces complications and enhances the safety during interventional treatment for patients with hepatocellular carcinoma.

The objective of this study was to investigate the therapeutic effect and safety of three-dimensional digital subtraction angiography (3D-DSA) in interventional therapy for hepatocellular carcinoma (HCC) patients.A total of 62 HCC patients who underwent interventional therapy were selected and divided into control group (n=31, receiving ordinary two-dimensional DSA) and observation group (n=31, undergoing 3D-DSA). The dosage of contrast agent, operation time and exposure dose were compared between the two groups. Besides, the effective rate, success rate of superselective arterial catheterization, lipiodol deposition rate and the incidence rate of complications of the two groups were observed and recorded.Compared with those in control group, the dose of contrast agent and exposure dose were lower in observation group, and the operation time in the former was significantly shorter than that in the latter. The effective rate was 74.19% in observation group and 48.39% in control group. Moreover, in comparison with control group, operation group exhibited a higher effective rate, a higher success rate of superselective arterial catheterization and a higher lipiodol deposition rate, showing statistically significant differences (p<0.05). Besides, the incidence rate of complications (including myelosuppression, gastrointestinal discomfort and infection, 4.88%) in observation group was markedly lower than that in control group (25.81%) (p<0.05).3D-DSA under contrast guidance during interventional treatment of patients with HCC can significantly improve the therapeutic effect, and it is of great importance to reduce the incidence rate of complications and enhance the safety of interventional treatment.
