Percutaneous rescue therapy in a child with blocked cavo-pulmonary shunt

A 7-month-old infant presented with bilateral blocked cavo-pulmonary anastomosis within 2 months of surgery. Due to extreme haemodynamic instability, surgical options were abandoned and rescue intervention from left jugular line was planned. Acute thrombosis of the left-sided Glenn was noted with significant anastomotic narrowing. Successful rescue thrombolysis was done using recombinant tissue plasminogen activator (Alteplase) along with balloon dilatation of the attenuated segments.
