Historical Perspective Electrothrombosis of Saccular Aneurysms via Endovascular Approach: Part 1

opment and clinical use of detachable balloons, neurointerventionalists throughout the world for the first time began attempts to treat intracranial aneurysms by using endovascular techniques (1, 2). Although the use of balloons for treatment of an-eurysms in circumstances where occlusion of the parent artery could be tolerated was a tremendous addition to endovascular therapy, the ability to use these devices in situations where parent artery pres-ervation was required was limited. The technique was technically challenging and the results were often unpredictable. Thus was the situation in 1991 when Guglielmi and colleagues reported on the use of an endovascular technique that combined elec-trolysis and electrothrombosis for the treatment o
