Neurointerventional Surgery

The University of Chicago Medicine neurointerventional surgery team specializes in minimally invasive techniques for the diagnosis and treatment of conditions of the brain, head and neck, spine and spinal cord. Neurointerventional surgical procedures are performed by interventional neuroradiologists — radiologists who have advanced training in image-guided, minimally invasive diagnostic and endovascular surgical techniques. Neurointerventional procedures take place on the medical campus in Hyde Park. 

For patients, the benefits of neurointerventional surgery (also commonly known as interventional neuroradiology) include smaller incisions, less risk, faster recovery and less pain than traditional surgery. Our team provides neurointerventional surgical care for many conditions that previously were untreatable or required more invasive, open surgical techniques.

Our interventional neuroradiologists use state-of-the-art diagnostic imaging techniques, including high-resolution MR imaging, 3D vascular imaging, and diagnostic cerebral and spinal angiographies.

Diagnostic Cerebral & Spinal Angiography

Our team performs cerebral and spinal angiograms as needed for diagnostic purposes, pre-surgical planning and post-surgical follow-up. After injecting contrast dye into the blood vessels, our specialists use high-resolution imaging equipment to capture detailed 3D pictures of the arteries and veins. Diagnostic angiograms usually are performed under light sedation on an outpatient basis.

Non-Invasive Imaging Studies

Using state-of-the-art 3T MR imaging machines and 64-slice multidetector CT scanners, specialists at UChicago Medicine provide high-quality, non-invasive neurovascular imaging services. Our interventional neuroradiologists oversee and perform high-resolution 3D vascular imaging, including intracranial arterial wall imaging and physiologic imaging studies, such as cerebral perfusion imaging, vascular wall shear stress imaging and cerebrovascular permeability imaging.

At UChicago Medicine, our physicians continually seek new ways to improve the diagnosis and treatment of neurovascular disorders. Our neurointerventional surgery experts are actively investigating acute stroke, advanced MR techniques and clinical outcomes.

The UChicago Medicine neurointerventional surgery team provides consultations for adults and children. Our team is comprised of specialists with extensive training and experience in neurointerventional surgical care, including advanced practice nurses, registered nurses and radiology technologists. The team is led by highly regarded UChicago Medicine physicians with proven expertise.

  • Seon-Kyu Lee, MD, PhD, is the director of neurointerventional surgery at UChicago Medicine. With extensive experience in all aspects of neurointerventional surgical procedures, he is a recognized expert in the field. In addition to providing the highest level of care for his patients, Dr. Lee participates in national and international clinical trials focused on improving strategies for stroke management.
  • Gregory A. Christoforidis, MD, is an interventional neuroradiologist and the section chief of neuroradiology at UChicago Medicine. He has expertise in all types of diagnostic and interventional neuroradiology procedures. Dr. Christoforidis is investigating the formation, maturation and roles of certain blood vessels in acute ischemic stroke brain tissues.
