Microneurosurgical management of giant intracranial aneurysms: Datasets of a twenty-year experience

The data presented in this brief paper aims to summarize the overall results of 82 consecutive patients surgically treated over 20 years for a giant intracranial aneurysm (GIA) in the context of the endovascular era. Data were retrospectively collected from the database of two different tertiary referral Italian hospitals. A retrospective analysis of the patients’ cohort was performed. Data are presented as they relate to the demographic and clinical aspects, the prevalence of GIAs according to anterior and posterior circulation, aneurysm angioarchitectural features, surgical treatment options, complications, outcome, and main microneurosurgical techniques required explicitly for GIAs, namely temporary clipping, aneurysm remodeling, thrombectomy, fragmentation, and bypass. Furthermore, data about the effects of implementing the flow-diverter/flow-disruptor on the surgical case volume over the years are also reported. The data presented herein are related to our previously published research article titled “Surgical Management of Giant Intracranial Aneurysms: Overall Results of a Large Series” (2020) [1].
