Convulsive syncope after bidirectional Glenn shunts: physiological implications for a neurological event.

Objectives: Neurological complications after cavopulmonary connections like bidirectional Glenn shunt and Fontan connection are occasionally encountered in the postoperative period. We discuss such a case of bilateral bidirectional Glenn shunt which developed convulsive syncope postoperatively.

Case: A 5-year-old cyanotic girl diagnosed as tricuspid atresia with pulmonary stenosis without any spell history underwent bilateral bidirectional Glenn shunt on the way to a subsequent Fontan.
