Researchers at the University of Washington have conducted a study on the use of smartphone pupillometry for the detection of acute large vessel occlusion (LVO) in patients with acute ischemic stroke (AIS). The study found significant alterations in pupillary light reflex (PLR) parameters in AIS patients with LVO before thrombectomy, suggesting the potential use of smartphone pupillometry for LVO detection. The study compared PLR parameters in healthy controls and AIS patients and analyzed the proprietary Neurological Pupil index (NPi) score. The research has been peer-reviewed and published in the Journal of Stroke and Cerebrovascular Diseases. [Extracted from the article]

A recent study conducted at the University of Texas Health Science Center in San Antonio has provided new insights into aneurysms and their treatment. The study focused on mechanical thrombectomy failure (MTF), which occurs in approximately 15% of cases. Researchers analyzed data from the Stroke Thrombectomy and Aneurysm Registry and found that factors such as age, poor pre-treatment modified Rankin Scale, number of passes, and procedure time were associated with MTF. The study also found that rescue intracranial stenting may decrease the likelihood of MTF for posterior circulation mechanical thrombectomy. [Extracted from the article]
