Interventional Neuroradiology

Trained as both a cerebrovascular surgeon and an endovascular neurointerventionalist, Dr. Robert Dodd represents the future trend for treating aneurysms, AVMs and arterio-venous fistulae (AVFs) with less invasive endovascular techniques that are safer for patients and shorten recovery times. In the last year, Dr. Dodd and his colleagues in Interventional Neuroradiology, treated 48% of the 248 aneurysm cases at Stanford with detachable coils. These are injected into the aneurysm via a catheter that enters the groin and is then navigated up to the brain aneurysm from inside the arteries. The coils then clot off the aneurysm from the inside to prevent future ruptures that could cause hemorrhage and stroke. Endovascular embolization of AVMs using a “super-glue” or liquid adhesive is often performed to facilitate subsequent therapies with microsurgery or radiosurgery. Brain and spinal cord AVFs can usually be cured by this technique alone.

Patients with acute ischemic stroke are also benefiting from endovascular therapies. Blood clots that plug up the brain’s arterial blood supply causing transient ischemic attacks (TIAs) or strokes, can now be mechanically removed with a tiny device called a Concentric Merci Retriever. Using the same method described above through a catheter, a corkscrew type device can pierce the blood clot allowing the skilled neurointerventionalist to then pull it out and restore normal blood flow. In the last year, 30 of these emergency thromboembolectomies were successfully performed using this technique along with the Penumbra Suction Catheter, which also safely removes blood clots.
