[Indication for lung biopsy and usefulness of lung biopsy].
The criteria of open lung biopsy for operative indication were determined on the basis of hemodynamics in each congenital cardiac anomalies with pulmonary hypertension. More than 10.6, 8 and 8 units. m2 of pulmonary vascular resistance (PVR) were considered as indication for open lung biopsy in the patients with complete transposition of the great arteries, complete atrioventricular canal defect and atrial septal defect respectively. Lung biopsy should be done in patients with ventricular septal defect when PVR is more than 8 units. m2 and if it is greater than 4 with the oxygen inhalation test or 6 with the Tolazoline test. The usefulness of lung biopsy was also emphasized on the basis of the postoperative result in which lung biopsy diagnosis has been done.
