LETTERS Regarding “Rate and Prognosis of Patients under Conscious Sedation Requiring Emergent Intubation during

ing Neuroendovascular Procedures”1 and appreciate the effort of Hassan et al to address the complicated, controversial issue of conscious sedation versus general anesthesia for neurointerven-tional procedures. As they appropriately noted, “Limitations of the methodology used in our study preclude us from offering specific recommendations regarding when to use a specific anes-thetic protocol.” Although Hassan et al1 clearly declare the limitations of their study, they nevertheless present a false equivalence.
