Transcatheter occlusion of a Blalock-Taussig shunt with a detachable balloon in a child.
A case of transcatheter occlusion of a Blalock-Taussig shunt with a detachable silicone filled balloon is described. This 11 year old boy had previously had a repair of tetralogy of Fallot together with ligation of a large Blalock-Taussig shunt. Though there was a good surgical result, the shunt proved to be incompletely closed leaving a significant left to right shunt. As an alternative to a f...
متن کاملPulmonary vascular disease complicating the Blalock-Taussig anastomosis.
The pulmonary vascular bed was evaluated following a Blalock-Taussig shunt performed in 36 patients for decreased pulmonary blood flow. The time of follow-up ranged from one to 21 years after operation. No patients developed severe pulmonary changes in less than eight years after institution of the shunt. Ten of 20 patients having a shunt eight years or longer developed some degree of pulmonary...
متن کاملCLINICOPATHOLOGIC CORRELATIONS Pulmonary Vascular Disease Complicating the Blalock-Taussig Anastomosis
ALTHOUGH THE BLALOCK-TAUSSIG SHUNT has been performed since 1945,1 the long-term effects upon the pulmonary vascular bed have been recorded only incompletely. While pulmonary vascular disease following the Waterston or Potts operations has been reported to occur in from 10 to 50% of cases, its incidence after the BlalockTaussig shunt has been thought to be much lower. Daoud,2 Hancock," and Robe...
متن کاملPercutaneous closure of a modified Blalock-Taussig shunt using an amplatzer vascular plug.
Modified Blalock-Taussig shunts are usually clamped during the successive corrective or palliative surgical procedures carried out to treat underlying congenital heart disease, though at times they may be left permeable for a number of reasons. Subsequently, when this is no longer considered necessary and closure is indicated, the method of choice is percutaneous embolization using various coil...
متن کاملImpact of 3-mm Blalock-Taussig shunt in neonates and infants with a functionally single ventricle.
Functionally single ventricle (f-SV) is susceptible to volume overload. Atrioventricular valve regurgitation (AVVR) tends to develop and ventricular function deteriorates due to excessive pulmonary blood flow following modified Blalock-Taussig shunt (mBTS). On the other hand, a small caliber graft has risks of early obstruction and poor growth of pulmonary vascular beds. We assessed the effect ...
