Association of Noncontrast Computed Tomography and Perfusion Modalities With Outcomes in Patients Undergoing Late-Window Stroke Thrombectomy.

Importance: There is substantial controversy with regards to the adequacy and use of noncontrast head computed tomography (NCCT) for late-window acute ischemic stroke in selecting candidates for mechanical thrombectomy.

Objective: To assess clinical outcomes of patients with acute ischemic stroke presenting in the late window who underwent mechanical thrombectomy stratified by NCCT admission in comparison with selection by CT perfusion (CTP) and diffusion-weighted imaging (DWI).

Design, Setting, And Participants: In this multicenter retrospective cohort study, prospectively maintained Stroke Thrombectomy and Aneurysm (STAR) database was used by selecting patients within the late window of acute ischemic stroke and emergent large vessel occlusion from 2013 to 2021.

Update in the Early Management and Reperfusion Strategies of Patients with Acute Ischemic Stroke.

Acute ischemic stroke (AIS) remains a leading cause of death and long-term disability. The paradigms on prehospital care, reperfusion therapies, and postreperfusion management of patients with AIS continue to evolve. After the publication of pivotal clinical trials, endovascular thrombectomy has become part of the standard of care in selected cases of AIS since 2015.

Spinal Cord Hemorrhage.

Background And Purpose: Spinal cord hemorrhages are rare conditions that can be classified based on the primary location of bleeding into intramedullary (hematomyelia), subarachnoid hemorrhage (SAH), subdural hemorrhage, and epidural hemorrhage. We conducted a literature review to better understand the presenting symptoms, etiology, diagnosis, and treatment of spinal cord hemorrhages.

Methods: We performed a literature search using PubMed with the key words spinal hemorrhage, hematomyelia, spinal subarachnoid hemorrhage, spinal subdural hematoma, and spinal epidural hematoma RESULTS: Most commonly, spinal hematomas present with acute onset of pain and myelopathy but a more insidious course also may occur.
