Advanced Neuro‑Interventional Radiologist Bringing Minimally Invasive Stroke and Aneurysm Care to Tyler, Texas

Dr. Gary Spiegel is a board‑certified neuro‑interventional radiologist in Tyler, Texas, specializing in minimally invasive treatment of complex brain, spine, and vascular conditions. Trained at McGill University Faculty of Medicine and the New York University Medical Center, with advanced fellowships in neuroradiology and neuroangiography, he has spent decades building and leading stroke and neurointerventional programs across the country. Today, he brings that expertise to East Texas, helping expand access to advanced stroke and neurovascular care for patients in the Tyler community.

Career at a Glance

• Fellowship‑trained in Diagnostic Neuroradiology and Surgical Neuroangiography (NYU Medical Center)
• Former Director of NeuroInterventional Surgery and Co‑Medical Director of a Stroke Center
• Academic faculty roles at UTHealth McGovern Medical School, Yale University, and University of Connecticut
• Contributor to early mechanical thrombectomy clinical trials (MERCI, Penumbra) shaping modern stroke care
• Active in national neurovascular societies, including SNIS and SVIN

Clinical Role and Leadership

Dr. Spiegel provides advanced neuro‑interventional care in Tyler as part of CHRISTUS Health, where he helps expand access to minimally invasive stroke and cerebrovascular treatment across the region. His background in leading stroke centers and building neurointerventional programs informs a patient‑centered approach focused on improving outcomes and reducing treatment delays.

He provides specialized care for conditions such as:

• Acute ischemic stroke
• Brain aneurysms
• Arteriovenous malformations (AVMs) and fistulas (AVFs)
• Carotid and intracranial atherosclerotic disease
• Subarachnoid hemorrhage and vasospasm
• Central venous thrombosis
• Spinal vascular malformations and tumors
