Systemic-to-pulmonary artery shunts using polytetrafluoroethylene (PTFE) (modified Blalock-Taussig shunt) are being used successfully in palliation of cyanotic congenital heart diseases. Graft thrombosis is by far the most common complication of the procedure. Persistant serum leakage through PTFE graft causing perigraft seroma is a rare but devastating complication resulting in increased durat...

A four year old boy with pulmonary atresia and ventricular septal defect had an acute cyanotic episode three years after undergoing a right-sided, 6 mm diameter, modified Blalock-Taussig shunt. On admission no continuous murmur could be heard from the shunt and the typical high velocity, continuous flow profile of the shunt could not be identified by Doppler echocardiography. At catheterisation...

The systemic to pulmonary artery shunts are done as palliative procedures for cyanotic congenital heart diseases ranging from simple tetralogy of Fallots (TOFs)/pulmonary atresia (PA) to complex univentricular hearts. They allow growth of pulmonary arteries and maintain regulated blood flow to the lungs till a proper age and body weight suitable for definitive corrective repair is reached. We h...

Here, we report a rare case of a 23-year-old term parturient with Eisenmenger syndrome due to Taussig-Bing anomaly presenting with gestational hypertension, oligohydramnios, and intrauterine growth retardation posted for elective cesarean section. Preoperatively, echocardiography of the patient was suggestive of double-outlet right ventricle (DORV) with large sub-pulmonic ventricular septal def...

In recent years, there has been a marked reduction in surgical mortality for many complex forms of congenital heart disease. Treatment or palliative strategies vary but may include systemic-pulmonary central or Blalock-Taussig shunt. These shunts can be complicated by overcirculation, infection, thrombosis, and thromboembolism. Many diagnostic modalities are available to aide in diagnosis of po...

A 6-month-old male Old English Bulldog with Tetralogy of Fallot (ToF) required general anaesthesia for surgical palliative treatment ToF whereby a shunt was placed between the left subclavian artery and pulmonary trunk to increase circulation (modified Blalock-Taussig shunt). Anaesthesia patient presents an anaesthetic challenge given four concurrent cardiac defects as well manoeuvres involved,...
