Abstract

The focus of this case report is to technically describe a noninvasive diagnostic evaluation of bow Hunter's syndrome using a dynamic computed tomography angiography protocol and discuss its advantages. In addition, we aimed to exemplify the quality of the study by presenting images of a 3D-printed model generated to help plan the surgical treatment for the patient. The dynamic computed tomography angiography protocol consisted of a first image acquisition with the patient in the anatomic position of the head and neck. This was followed by a second acquisition with the head and neck rotated to the side that triggered the symptoms, with technical parameters similar to the first acquisition. The acquired images were used to print a 3D model to better depict the findings for the surgical team. The dynamic computed tomography angiography protocol developed in this study helped visualize the vertebrobasilar arterial anatomy, detect vertebral artery stenosis produced by head and neck rotation, depict the structure responsible for artery stenosis (e.g., bony structure or membranes), and study possible complications of the disease (e.g., posterior cerebral circulation infarction). Additionally, the 3D-printed model better illustrated the findings of stenosis, aiding in surgical planning. In conclusion, dynamic computed tomography angiography for the evaluation of bow Hunter's syndrome is a feasible noninvasive technique that can be used as an alternative to traditional diagnostic methods.

动态计算机断层扫描血管造影用于弓形亨特综合征的无创诊断:病例报告。
本病例报告的重点在于从技术上描述使用动态计算机断层扫描血管造影方案对弓形亨特综合征进行的无创诊断评估,并讨论其优点。此外,我们还旨在通过展示 3D 打印模型的图像来体现研究的质量,以帮助规划患者的手术治疗。动态计算机断层扫描血管成像方案包括第一次图像采集,患者处于头颈部解剖位置。随后进行第二次采集,将头颈部旋转到引发症状的一侧,技术参数与第一次采集相似。采集到的图像被用于打印三维模型,以便为手术团队更好地描述检查结果。本研究中开发的动态计算机断层扫描血管成像方案有助于观察椎基底动脉解剖结构,检测头颈旋转造成的椎动脉狭窄,描述造成动脉狭窄的结构(如骨性结构或膜),研究疾病可能的并发症(如后脑循环梗死)。此外,3D 打印模型能更好地显示狭窄的发现,有助于手术规划。总之,用动态计算机断层扫描血管造影术评估弓形亨特综合征是一种可行的无创技术,可作为传统诊断方法的替代方法。
