SEATTLE, July 20, 2026
The Society of NeuroInterventional Surgery (SNIS) has unveiled a series of groundbreaking scientific presentations for its 23rd Annual Meeting, featuring a pioneering AI-guided brain tumor mapping technology, new findings on stroke treatment outcomes, the impact of anesthesia selection during thrombectomy, and major research examining racial disparities in cerebrovascular care. Taking place from July 20–24 at the Seattle Convention Center, the meeting will showcase more than 70 scientific studies that reflect the rapid evolution of neurointerventional medicine, emphasizing innovations that have the potential to improve diagnosis, precision treatment, patient outcomes, and healthcare equity. The featured research highlights how artificial intelligence, advanced endovascular techniques, and large-scale clinical analyses are reshaping the future of neurological disease management.
AI Technology Expands Precision Treatment for Brain Tumors
Among the most anticipated presentations is a novel AI-guided multi-territory endovascular therapy designed to map an entire brain tumor vascular network, rather than focusing on a single feeding artery. The innovative technology enables physicians to identify every blood vessel supplying the tumor, allowing targeted chemotherapy delivery throughout the complete tumor circulation. This comprehensive mapping strategy has the potential to improve therapeutic precision while maximizing drug delivery to cancer tissue and minimizing exposure to surrounding healthy brain structures. Researchers believe this advancement could significantly enhance the effectiveness of endovascular neuro-oncology procedures, representing an important step toward more personalized treatment strategies for patients with complex brain tumors. The presentation demonstrates how artificial intelligence continues to transform image-guided interventions and precision medicine within neurointerventional surgery.
New Stroke Research Explores Outcomes, Anesthesia and Health Equity
In addition to advances in neuro-oncology, SNIS will present several important studies focused on acute ischemic stroke treatment and long-term patient outcomes. Investigators will report new evidence evaluating the relationship between general anesthesia use during mechanical thrombectomy and patient mortality using data from the Neurovascular Quality Initiative Registry. Additional research will examine how successful reperfusion therapy influences functional recovery among patients with pre-existing disabilities before stroke onset. Beyond clinical treatment strategies, researchers will also present extensive analyses exploring racial disparities in endovascular thrombectomy, statewide investigations into social determinants of hemorrhagic stroke mortality, and differences in cerebrovascular outcomes across rural and urban populations. These studies aim to identify healthcare inequalities while supporting the development of evidence-based strategies that improve access to high-quality stroke care across diverse patient populations.

SNIS Highlights Innovation Driving Future Neurointerventional Care
The 2026 SNIS Annual Meeting will also feature educational sessions led by internationally recognized experts alongside presentations covering emerging techniques for pain management, cerebrovascular interventions, and next-generation image-guided therapies. A featured highlight will be the Grant Hieshima Luminary Lecture, delivered by Dr. Joshua Hirsch, an internationally respected interventional neuroradiologist recognized for his extensive contributions to neurointerventional science and clinical research. According to SNIS leadership, the conference serves as a premier platform where innovative research is translated into clinical practice, helping establish future standards of care for diseases affecting the brain, spine, head, and neck. With more than 70 scientific abstracts presented over four days, the meeting underscores the growing role of artificial intelligence, precision imaging, advanced endovascular procedures, and multidisciplinary collaboration in improving neurological patient care. Collectively, these presentations demonstrate how technological innovation and evidence-based research continue to redefine neurointerventional medicine while supporting better outcomes for patients worldwide.
