Interventional Neuroradiology

The Ohio State University Medical Center provides life-saving treatment for patients suffering ischemic stroke. Interventional neuroradiology, also called intra-arterial thrombolysis, is a minimally invasive technique that allows doctors to see inside the body and treat without surgery.

By inserting a thin tube (catheter or microcatheter) through a tiny needle stick in the upper leg, the doctor is able to guide the tube through the blood vessels to the site of the blockage that is restricting the brain’s blood supply and causing the stroke. Once in place, the tube delivers tPA, a drug used to treat ischemic strokes, to dissolve the clot (blockage) and restore blood flow. When this treatment is initiated during the first six hours of a stroke’s onset, it can save lives, improve the outcome of stroke, and a patient’s quality of life afterward.

The interventional neuroradiologist is a key member of the OSU Stroke Team, a multidisciplinary group of specialists, which includes stroke neurologists, neurosurgeons and interventional neuroradiologists, pharmacists, rehabilitation specialists, emergency physicians and nursing staff.
