摘要 目的:探讨肝癌介入治疗中旋转数字减影血管造影(Digital Subtraction Angioraphy,DSA)三维重建技术的应用价值。方法:对我院收治的52例肝癌患者分别行常规DSA和旋转DSA检查,然后将所得旋转DSA图像应用三维重建技术使用多种后处理软件,显示患者的血管和病灶,并与常规DSA图像对比。结果:52例患者中,旋转DSA配合三维重建技术均能够较清晰地显示肿瘤和供血血管之间的关系,并且能清晰显示供血动脉的角度;而常规DSA检查结果中,有12例患者无法清晰显示肿瘤供血动脉,其中2例患者在主病灶周围还存在较小子病灶,但是常规DSA检查无法清晰显示子病灶的供血动脉,两种方法肿瘤和供血血管显示总有效率差异具有统计学意义(P=0.001)。结论:在肝癌介入治疗中,采用旋转DSA三维重建技术具有明显优势,可以清晰显示肿瘤和供血动脉的关系以及供血动脉的角度,是对常规DSA检查的重要补充。 Objective To study on the application value of three-dimensional reconstruction technique of rotational digital subtraction angioraphy (rotational 3D-DSA) in the interventional treatment for liver cancer. Methods Admitted to our hospital, 52 patients with liver cancer were respectively examined by conventional DSA and rotational DSA. The acquired rotational DSA images were processed by 3D reconstruction technique and a variety of post-processing software was applied to present patients' blood vessels and lesions. And then the patients' blood vessels and lesions of rotational DSA images were compared with those of conventional DSA images. Results Among the 52 patients, rotational 3D-DSA clearly showed the relationship between tumor and supply vessels, and the perspective of supply arteries, while the conventional DSA examination results showed the tumor supply arteries of 12 patients could not be clearly presented and that the supply arteries of small lesions around the main lesion of 2 patients could not be clearly presented. The efficiency difference of the two methods had statistical significance (P=0.001). Conclusion In the interventional therapy for liver cancer, rotational 3D-DSA has obvious advantages, clearly showing the relationship between tumor and supply arteries, and the perspective of supply arteries, which is an important supplement for the conventional DSA examination.
