[Percutaneous pulmonary balloon dilatation in complex congenital defects].

Since several years percutaneous balloon dilatation has gained more and more importance as a method circumventing thoracotomy. Induced by the results in the international literature [1-14] we performed successfully percutaneous pulmonary balloon dilatations in 8 patients between June 1988 and March 1990. Three patients (aged 6.5 to 27 years) had an isolated, prevailing valvular pulmonary stenosis, while the five others had a complex congenital anomaly with valvular and subvalvular pulmonary stenosis. The paper reports the results of pulmonary balloon dilatations in the latter five patients.
