Bidirectional Glenn shunt is a well-established 
procedure performed as a part of the single 
ventricle palliation pathway. It may also provide 
definitive palliation in certain other patients. 
However, stroke and neurocognitive dysfunction 
are common after surgery with rates of 
approximately 3e6% and 30e50%, respectively. 
This study aimed to report and compare early 
post-operative neurological outcome after onpump and off pump using temporary cavo atrial 
shunt in bidirectional Glenn shunt operation 
using a neurological monitor.
