Fellowship Information

Join one of the most established and advanced CAST-accredited cerebrovascular centers in the Midwest, with a rich history in the field as the second institution in the world to coil cerebral aneurysms (1991). Our experienced faculty offer the entire array of treatments for vascular disease of the CNS state-of-the-art clinical and research equipment complement innovative imaging protocols in technologically advanced procedures.

From July 2020 to July 2022, 389 intracranial aneurysms were treated at University Hospital (232 treated endovascularly), 115 craniotomies for AVM/AVF resection (60 arteriovenous malformations or arteriovenous fistulas embolization procedures) and 1309 diagnostic-only angiograms (diagnostic only cerebral and spinal angiograms). UW Health’s Neuroendovascular Surgery program continues to innovate and lead as one of the first certified comprehensive stroke centers in the U.S., performing 305 acute ischemic stroke thrombectomies from 2020 to ’22.
