IaN for aSAH-related cerebral vasospasm did not improve rScO2 but was associated with significant systemic hemodynamic effects, including a decrease in MBP and TPRI. These hemodynamic changes might offset any potential effects of IaN to improve rScO2.
The benefit of retrograde cerebral perfusion (RCP) with profound hypothermic circulatory arrest has been subject to much debate. We examined our experience with ascending and transverse arch repairs to determine the impact of retrograde cerebral perfusion on stroke and mortality.
