We used initial plain computed tomography to delineate acutely occluded internal carotid arteries or horizontal segments of middle cerebral arteries. If affected arteries could be delineated using initial plain computed tomography, useful information might be obtained that could support endovascular thrombectomies.
In 15 patients with occluded internal carotid arteries or horizontal segments of middle cerebral arteries, the affected middle cerebral artery was automatically traced using the extender function for blood vessel tracing with reference to the default value (window setting, 40; window width, 90) on Ziostation 2 (Ziosoft Inc., Tokyo, Japan) based on initial plain computed tomography data.
The horizontal and sylvian segments of the middle cerebral artery were delineated in 15 and nine patients, respectively, based on plain computed tomography volume data. Images of occluded vessels delineated by plain computed tomography closely correlated with digital subtraction angiography.
Initial plain computed tomography combined with a new generation workstation enabled the rapid delineation of occluded segments of intracranial vessels and could provide useful information that might improve the safety of endovascular thrombectomy.
我们使用初始平扫 CT 来描绘急性闭塞的颈内动脉或大脑中动脉水平段。如果可以使用初始平扫 CT 描绘受影响的动脉,则可能获得支持血管内取栓术的有用信息。
在 15 例颈内动脉或大脑中动脉水平段闭塞的患者中,使用 Ziostation 2(Ziosoft Inc.,东京,日本)上的血管追踪扩展功能,参考默认值(窗宽设置为 40,窗宽为 90),自动追踪受影响的大脑中动脉,基于初始平扫 CT 数据。
基于平扫 CT 容积数据,15 例患者的大脑中动脉水平段和大脑外侧裂段被描绘出来,9 例患者的大脑中动脉水平段被描绘出来。平扫 CT 描绘的闭塞血管图像与数字减影血管造影密切相关。
初始平扫 CT 结合新一代工作站可快速描绘颅内血管闭塞段,提供可能提高血管内取栓术安全性的有用信息。
