[Percutaneous transluminal angioplasty using balloon catheter in a Blalock-Taussig pulmonary-systemic fistula].
Percutaneous transluminal balloon angioplasty has been used successfully in the treatment of valvular and vascular stenosis. This article describes our experience with this technique to improve pulmonary blood flow in a patient with a severely stenotic Blalock-Taussig (B-T) systemic-to-right pulmonary artery anastomosis, with improvement in oxygen peripheric saturation from 33 to 78% immediately postdilatation and 69% three months later. Hemoglobin decreased from 20.4 to 18.9 gm/dl and hematocrit from 64% to 58.5%. In conclusion we think that this technique is an alternative instead of cardiac surgery, in these cases the procedure is only palliative.
