This descriptive study explores typical patterns of vascular territory mapping (VTM) in ischaemic stroke patients with proximal vessel occlusion. VTM is a novel process using CT perfusion that can identify the source and extent of collateral blood flow in patients with vessel occlusion. It functions by determining which vessel provides dominant blood flow to a brain voxel.
A total of 167 consecutive patients were analysed from INSPIRE (International Stroke Perfusion Imaging Registry) with their CT perfusion reprocessed through VTM software. We explored the typical territory maps generated by this software relating to common large vessel occlusion location sites (ACA/MCA/PCA).
RESULTS/CONCLUSION: In the presence of occlusion, VTM demonstrated a reciprocal increase in collateral vessel territories.
本描述性研究探讨了近端血管闭塞的缺血性脑卒中患者中血管供血区图谱(VTM)的典型模式。VTM 是一种利用 CT 灌注进行的新方法,可识别血管闭塞患者的侧支血流来源和范围。它的作用是确定哪个血管为脑像素提供主导血流。
对来自 INSPIRE(国际卒中灌注成像登记处)的 167 例连续患者进行分析,对其 CT 灌注进行 VTM 软件重新处理。我们探讨了该软件生成的与常见大血管闭塞部位(ACA/MCA/PCA)相关的典型供血区图谱。
结果/结论:在存在闭塞的情况下,VTM 显示出侧支血管供血区的相互增加。
