    Abstract:
    BACKGROUND: In an era of continued advancements in endovascular treatment of cerebral aneurysms, novel developments concerning microsurgical clipping are sparse. The Lazic aneurysm clip system represents such an advancement. The applier has a malleable shaft and is designed to minimally obstruct the view of the surgical field. The purpose of this study was to illustrate the transition to this new aneurysm clip system in an established cerebrovascular practice. METHODS: We retrospectively reviewed all aneurysms treated with microsurgical clipping using the Lazic aneurysm clip system in 1 cerebrovascular practice in the United States from January 2009 to June 2016. RESULTS: Between 2009 and 2016, a total of 973 aneurysms underwent surgical clipping. The Lazic clip system was used in 191 (19.6%) aneurysms (maximum diameter, 5.6 ± 3.8 mm) in 181 patients. The middle cerebral artery was the most frequent location (25.7%) followed by posterior communicating artery (20.9%). There was a continuous increase in the percentage of aneurysms treated with the Lazic clip system from 6% in 2009 to 98% in 2016. The proportion of posterior circulation aneurysms treated with Lazic clips decreased, whereas the middle cerebral artery location increased. There were a total of 11 complications (5.8%), but no instances of clip malfunction. CONCLUSIONS: In the largest series to date, the Lazic clip system proved to be safe and efficacious and presents an interesting alternative to established aneurysm clip systems. This study illustrates the transition of an established cerebrovascular practice to the Lazic clip system.
