Objective: With increasing frequency, 3D4K exoscope systems (EX) are being used in neurosurgery and are often described as feasible alternatives to conventional microscopes (OMs). In this study, we review and report our experience using the Orbeye® exoscope (Olympus, Germany) in microsurgical aneurysm repair compared with the conventional OM.
Methods: A retrospective analysis of patients who underwent microsurgical repair of incidentally or ruptured cerebral aneurysms between 8/2018 and 8/2020 was performed. Individual patient-, disease related and aneurysm characteristics were evaluated. Data on surgery duration were assessed and correlated with the OM cohort for time trend and comparability. In addition, technical aspects were evaluated in terms of reliability.
Results: 185 aneurysm cases were identified during the mentioned period. The EX was used for surgery in 44 cases. The mean surgical duration was in a comparable time frame with no statistically significant difference between the devices (165.5 ± 45.8 minutes (EX) vs. 160.5 ± 39.2 minutes (OM), p>0.05). Rates of complete aneurysm occlusion (95.5% (EX) vs. 92.2% (OM), p>0.05) as well as postoperative complications (9.1% (EX) vs. 9.7% (OM), p>0.05) were also comparable. In none of the cases with the EX did technical problems occur, likewise a switch to the OM was not necessary.
Conclusion: The results of our study provides equipoise with the OM in vascular microsurgery. Because of the ease of use and comparable surgical results the EX widens the spectrum of visualization tools and allows choice of tool according to individual surgeons’ preferences.
