Neurological repercussions of changes in cerebral blood flow in neonates undergoing cardiovascular surgery.

Introduction: Surgery for congenital heart disease can generate cerebral perfusion-associated alterations with neurological repercussions.

Objective: To analyze the relationship of peri-surgical cerebrovascular resistance index (RI) with mediate neurological functions after congenital heart disease surgery.

Method: Prospective cohort study of 34 neonates in whom basilar artery RI, serum oxygen, carbon dioxide and lactate levels were determined before and after palliative or corrective procedures.
