Total-tau and neurofilament light in CSF reflect spinal cord ischaemia after endovascular aortic repair

The CSF biomarkers NFL and T-tau both reflect development of SCI after endovascular aortic repair, but do not rise until after clinical signs of SCI appear. Future studies are desirable to further evaluate potential use of these biomarkers for assessment of the severity of SCI, and also to identify earlier biomarkers of SCI.
