| Abstract: | Objective The purpose of this study was to explore the availability of using color Doppler flow imaging (CDFI) to evaluate the effect of retrograde cerebral perfusion (RCP) during deep hypothermic circulatory arrest (DHCA). Methods Fundus vessels were studied in three piglets using CDFI before cardiopulmonary bypass and during RCP.Results CDFI showed that flow signals were detected in all of the observed vessels during RCP. Conclusion CDFI is a direct and sensitive method for observing cerebral blood flow and can assess the effect of cerebral perfusion |
