The advent of novel endovascular technology has expanded the applicability of endovascular therapies; however, the superiority of novel embolic devices over the traditional Guglielmi detachable coils is still debated. We performed a systematic review of literature that reported the Raymond\u2013Roy occlusion classification (RROC) rates of modern endovascular devices to determine their immediate and follow\u2010up occlusion effectivenesses for the treatment of unruptured saccular intracranial aneurysms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">A search was conducted using electronic databases (PUBMED, Cochrane, ClinicalTrials.gov, and Web of Science). We retrieved studies published between 2000 and 2022, reporting immediate and follow\u2010up RROC rates of subjects treated with different endovascular intracranial aneurysm therapies. We extracted demographic information of the treated patients and their reported angiographic RROC rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      A total of 80 studies from 15 countries were included for data extraction. The RROC rates determined from angiogram were obtained for 21\u00a0331 patients (72.5% women, pooled mean age: 58.2 [95% CI]: 56.8\u201359.6), harboring 22\u00a0791 aneurysms. The most frequent aneurysm locations were the internal carotid artery (46.4%, 95%\u00a0CI: 41.9%\u201350.9%), the anterior communicating artery (26.4%, 95%\u00a0CI: 22.5%\u201330.8%), the middle cerebral artery (24.5%, 95%\u00a0CI: 19.2%\u201330.8%), and the basilar tip (14.4%, 95%\u00a0CI: 11.3%\u201318.3%). The\n                      <jats:italic>complete<\/jats:italic>\n                      occlusion probability (RROC\u2010I) was analyzed for Guglielmi detachable coils, the Woven EndoBridge, and flow diverters. The RROC\u2010I rate was the highest in balloon\u2010assisted coiling (73.9%, 95%\u00a0CI: 65.0%\u201381.2%) and the lowest in the Woven EndoBridge (27.8%, 95%\u00a0CI: 13.2%\u201349.2%). The follow\u2010up RROC\u2010I probability was homogenous in all analyzed devices.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      We observed that the coil\u2010based endovascular therapy provides acceptable rates of complete occlusion, and these rates are improved in balloon\u2010assisted coils. Out of the analyzed devices, the Woven EndoBridge exhibited the shortest time to achieve &gt;90% probability of follow\u2010up complete occlusion (\u223c18\u00a0months).
