Table 4 Role of TCD during regional low-flow perfusion for neonatal aortic arch reconstruction.

From: Cerebral blood flow during cardiopulmonary bypass in pediatric cardiac surgery: the role of transcranial Doppler – a systematic review of the literature

Author [reference] Journal (Year of Publication) Type of study and Number of patients Main findings
Pigula F [19] Journal of Thoracic Cardiovascular Surgery (2000) Observational on 6 neonates Significant decreases are shown in both cerebral blood volume and oxygen saturation in children who underwent repair with DHCA as compared with children with RLFP.
Andropulos D [20] Journal of Thoracic Cardiovascular Surgery (2002) Observational on 34 neonates The use of TCD is able to maintain cerebral oxygen saturations and blood flow velocities within 10% of baseline, in order to prevent cerebral hyperperfusion during periods with high NIRS saturation values.
