头颈部3D-CTA与DSA影像融合技术在神经介入手术中的初步应用价值

Initial application of head and neck 3D-CTA fused with DSA imaging in neurointerventional procedures

摘要:

目的 分析探究头颈部三维CT血管造影（3D-CTA）与数字减影血管造影（DSA）影像融合技术在神经介入手术中的初步应用价值。方法 选取2019年3月至2021年3月许昌中医院期间收治的70例神经介入治疗患者为本次研究对象。根据随机数表法将所有患者分为对照组与观察组，各35例。对照组患者进行术中DSA辅助检查及治疗，观察组患者进行术中3D-CTA联合DSA辅助检查及治疗，对两组手术治疗效果进行对比。结果 对比两组图像融合情况，发现观察组融合成功率高于对照组（P<0.05）；观察组所用照射剂量及造影剂剂量均低于对照组（P<0.05）。结论 为神经介入治疗患者应用头颈部3D-CTA联合DSA影像融合诊断技术更能有效减少放射量，可控制造影剂的剂量，可为临床治疗提供科学全面的诊断依据，降低手术治疗风险，值得在实际工作中进行应用与推广。

Abstract:

Objective To analyze and investigate the preliminary application of head and neck three-dimensional computed tomography angiography (3D-CTA) fused with digital subtraction angiography (DSA) imaging in neurointerventional procedures.Methods Seventy neurointerventional patients who were admitted to Xu Chang Hospital of Traditional Chinese Medicine between March 2019 and March 2021 were selected as subjects of this study. All patients were divided into control group and observation group according to the random number table method, 35 patients in each group. Patients in the control group were provided with intraoperative DSA assisted examination and treatment, patients in the observation group were provided with intraoperative 3D-CTA fused with DSA assisted examination and treatment, and the effects of surgical treatment in the two groups were compared.Results Comparing the fusion of images between the two groups, we found that the fusion success rate of the observation group was higher than that of the control group (P<0.05). The dose of irradiation (mGy) and the dose of contrast medium (mL) used in the observation group were lower than those of the control group (P<0.05).Conclusion To apply 3D-CTA fused with DSA of head and neck diagnosis technology in patients with neurointerventional treatment can more effectively reduce the amount of radiation and controllably manufacture the dose of shadow agents, which can provide scientific and comprehensive diagnostic evidence for clinical treatment and reduce the risk of surgical treatment, and it is worth application and promotion in practical work.
