Abstract
- Introduction: We aimed to evaluate venous delay before and after treatment as a marker of radiological and clinical outcome in stroke patients receiving endovascular treatment (EVT). Methods: Prospective cohort of patients with anterior intracranial occlusion undergoing EVT. Brain MRI was performed on arrival (pre-EVT), Results: From 98 included patients (median NIHSS 17, final mTICI≥2b 86%), 89 pre-EVT dMRIs and 88 post-EVT dMRIs were evaluable. The median venous delay pre-EVT and post-EVT were -31.9[-58.1;-16.7]% and -13.5[-34.5;-7.5]%, respectively. Venous delay pre-EVT was not related to infarct volume or clinical outcome. When final mTICI≥2B, venous asymmetry decreased but still persisted. For each 10% of increment in venous delay post-EVT, there was an adjusted increase of 0.12[0.05-0.19]ml in the final infarct volume. Venous delay post-EVT was independently associated with mRS at 90 days (cOR 1.013 [95%CI 1.001-1.0256]). Conclusion: Cortical vein delay assessed after but not before EVT, is associated with a larger final infarct volume and with a worse clinical outcome.
