RESUMEN
Permeability of a Blalock-Taussig shunt can increase the risk of endocarditis and ventricular overload. Percutaneous embolization of these shunts gives variable results. We report our experience in 10 patients with percutaneous closure of modified Blalock-Taussig shunts using retrograde arterial embolization with Gianturco coils. The patients' median age was 2.8 years, and their median weight was 12 kg. Most patients had minor stenosis of the distal portion of the anastomosis. In all cases, complete closure of the shunt was achieved without complications using a median of one coil per patient. The technique was feasible, safe, effective, and inexpensive.

La permeabilidad de una fístula de Blalock-Taussig incrementa el riesgo de endocarditis y sobrecarga ventricular. Los resultados de la embolización percutánea de estos cortocircuitos son variables. Presentamos la experiencia en el cierre percutáneo de la fístula de Blalock-Taussig modificada, utilizando la embolización arterial retrógrada con espirales de Gianturco, en 10 pacientes. Las medianas de edad y peso fueron 2,8 años y 12 kg, respectivamente. La mayoría presentaba una zona de disminución del diámetro en el extremo distal de la conexión. En todos se consiguió un cierre completo del cortocircuito, con una mediana de 1 dispositivo por paciente, y no se registraron complicaciones. La técnica es factible, segura, efectiva y económica (AU)
