Experience with the modified Blalock-Taussig operation using polytetrafluoroethylene (Impra) grafts.

Modified Blalock-Taussig operation using polytetrafluoroethylene (Impra) grafts.

Perigraft seroma complicating the modified Blalock-Taussig shunts: two consecutive instances with review of literature.

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...

Blalock - Taussig shunt . modified ( polytetrafluoroethylene ) Balloon dilatation of a stenosed

A 17 month old girl with tricuspid atresia, ventricular septal defect, subvalvar and valvar pulmonary stenosis, and increasing cyanosis had angiographic evidence ofproximal stenosis of a right modified (5 mm diameter) Blalock-Taussig shunt. She underwent palliative balloon angioplasty with a 6 mm Schneider balloon catheter. Successful dilatation was achieved without complication. Four months la...

Infection of modified Blalock shunts.

A left-sided interposition graft (modified Blalock-Taussig anastomosis) was constructed with polytetrafluoroethylene in a three month old child with tetralogy of Fallot. This shunt thrombosed and a replacement shunt became the site of chronic Pseudomonas infection. The second anastomosis was excised and a third interposition graft was inserted on the right side because the anatomy was unsuitabl...

Modified Blalock-taussig Shunt ----in- Hospital Shunt Occlusion: Experience at Nicvd

A modified Blalock-Taussig shunt (mBTS) is a surgically placed graft between the systemic and pulmonary arterial circulations that redirects systemic blood flow into the pulmonary circulation. It is often placed in those with rightsided obstructive cardiac defects to increase pulmonary blood flow. Postoperative shunt patency is critical to adequate systemic oxygenation. Nevertheless, in the imm...
