Title: How Safe and Effective Is Shifting from Pterional to Supraorbital Keyhole Approach for Clipping Ruptured Anterior Circulation Aneurysms? A Surgeon’s Transition Phase Comparative Study
Abstract: Comparative studies between standard pterional and supraorbital keyhole approaches for aneurysms had potential biases with the heterogeneity of patient selection, differences among surgeons, or varying expertise across the surgeon's learning curve. This is a study of a surgeon's transition from pterional to keyhole approach for early clipping of selected consecutive ruptured anterior circulation aneurysms.
