Enhancing Neurovascular Safety: Real-Time Detection of Posterior Circulation Ischemia Using Cerebellar NIRS
In modern neurovascular care, one of the greatest challenges lies in managing the unpredictability of cerebral ischemia , especially during delicate endovascular procedures. Among these, vertebral artery stenting is particularly complex due to its proximity to the posterior circulation , which supplies critical brain structures such as the cerebellum and brainstem. Even brief interruptions in blood flow can result in devastating neurological outcomes. At the forefront of addressing this challenge is Dr. Vimal Rangarajan , Head of the Department of Anesthesia at KD Hospital , Ahmedabad, India. With a strong foundation in anesthesiology from BJ Medical College, Gujarat University, Dr. Rangarajan has been instrumental in advancing intraoperative monitoring techniques—particularly the application of cerebellar near-infrared spectroscopy (NIRS) for real-time detection of posterior circulation ischemia. Understanding the Clinical Challenge Posterior circulation strokes account for a...
