Exoscopic Clipping of Aneurysms - One-year Experience

Background: Microsurgical clipping of aneurysms is the cornerstone in the management of ruptured and unruptured aneurysms. Exoscope offers enhanced ergonomics with high-definition three-dimensional images. Our study aims to describe our institutional experience in clipping aneurysms over 1 year using the exoscope. Materials and Methods: A single-centre retrospective analysis of 32 patients (demographics, presentation, outcomes and complications) undergoing exoscopic aneurysm clipping at the department of neurosurgery at our centre was done. Results: Thirty (93.75%) patients had ruptured aneurysms and two (6.25%) had unruptured aneurysms; significant improvements were observed in modified Rankin scale (mRS) scores at 3 months ( P < 0.0001). Mortality was seen in 4 (12.50%), poor outcomes (mRS >2) were seen in 12%. Conclusion: Exoscope-assisted clipping demonstrates efficacy in achieving stable functional outcomes for survivors, surpassing the ergonomic advantages of conventional operating microscopes, though larger studies are required to validate exoscope-specific advantages.
