There is an increasing stroke burden in our aging population, as the risk of stroke increases twofold every 10 years after the age of 55. Demographic, procedural, and outcome variables, such as 90-day modified Rankin scale (mRS), mortality, and National Institute of Health Stroke Scale (NIHSS), were compared between patients less than 80 years old (n = 162) and 80+ years old (n = 70). On initial presentation at the hospital, patients aged 80 and older were more likely to present with higher NIHSS (17.1, SD 5.8) than the younger patients (15.3, SD 6.9, P = 0.02).

Two sets of CTP and DWI maps: (1) 116 lesions from patients from a large academic center (LAC) who presented with ischemic stroke and (2) 94 lesions from the 2018 Ischemic Stroke Lesion Segmentation (ISLES) challenge were combined for the project. The ISLES patients presented within 8 hours of stroke onset and underwent a DWI within 3hrs after CTP while LAC patients averaged 15 hours. [Extracted from the article]

Parameters recorded included patient demographics, location of stenosis, pre- and posttreatment manometric venous sinus and internal jugular pressure measurements, and symptoms before and after treatment. Posttreatment mean gradients were 2 mm Hg for venous sinus stenosis and 1.5 mm Hg for jugular stenosis (no treatment yet for the C1-level patient). Intracranial hypertension caused by venous stenosis is a complex pathophysiological phenomenon with symptoms that correlate with observed manometric findings. [Extracted from the article]

4:12 PM Abstract No. 714 FEATURED ABSTRACT Y-90 endovascular radiosurgery for the treatment of glioblastoma multiforme: a pilot study in a canine model To evaluate the safety and feasibility of Y-90 endovascular radiosurgery (ER) in the treatment of glioblastoma multiforme in a canine model. Tumor volume decreased by 69% and 59% in P1 and P2 on postcontrast MRI and by 24% and 26% in P3 and P4 on FLAIR MRI. [Extracted from the article]

The purpose of this study is to evaluate the effectiveness of DCNNs in the identification of either celiac artery, superior mesenteric artery (SMA), or cerebral internal carotid artery (ICA) in DSA frames. This is an IRB-approved study, with an image database created retrospectively using DSA images of celiac, SMA, and cerebral ICA arteriograms from December 2017 to July 2019. DCNNs were able to identify cerebral ICA, SMA, and celiac arteries on DSA images with a high degree of accuracy. [Extracted from the article]
