Tag: perfusion

Retrograde cerebral perfusion (RCP) is a neuroprotective technique originally described in the early 1990s to deliver cold, oxygenated blood via the cardiopulmonary bypass (CPB) circuit to the cerebral vasculature by way of the superior vena cava (SVC) during deep hypothermic circulatory arrest (DHCA) typically utilized for aortic surgery involving the…

Deep hypothermic circulatory arrest (“circ arrest”) is often required for partial or total aortic arch reconstructions. At this point in the surgery, there is no blood flow anywhere. Because of systemic cooling, we mitigate the anaerobic and calcium-mediated apoptotic pathways that are implicated in neuronal dysfunction and can safely perform…
