Association of Estimated Arterial Stiffness with Collateral Status and Functional Outcome after Endovascular Thrombectomy: A Secondary Analysis of the OPTIMAL-BP Trial

PURPOSE: Estimated pulse wave velocity (ePWV) is a surrogate of arterial stiffness that may influence stroke outcomes and potentially affect collateral circulation. We examined the association of ePWV with collateral status and 3-month functional outcome after successful endovasc...

Vascular Imaging Features and Time-Specific Recurrence Risk After Craniocervical Artery Dissection

Background and ObjectivesCraniocervical artery dissection (CCAD) is a major cause of stroke in young adults, yet its recurrence risk remains poorly defined because of delayed enrollment in prior research. We aimed to determine the temporal distribution of recurrent ischemic strok...
