A. The Major Advances in Neurosurgery

Narrator: This is Science Today. The advances in neurosurgery have been incredible, including the move towards less invasive surgeries with better results. UCLA's Division of Neurosurgery is celebrating their 50th year, and division chief Neil Martin says so much has happened in that relatively short span of time.

Martin: For instance, the treatment of intercranial aneurysms is something where there's been major breakthroughs. Less invasive, safer microsurgical approaches for treating aneurysms are the norm now.

Narrator: About ten years ago, one of the most exciting developments in treating intercranial aneurysms occurred at UCLA.

Martin: Aneurysms can now be treated with a procedure similar to a cardiac angioplasty where a catheter is threaded through the body's arteries into the aneurysm inside the head and the aneurysm filled with very soft, pliable coils. That seals it from the inside and has an effect in many cases similar to that we have achieved in the past with open brain surgery.
