[Findings of combined ventilation/perfusion scintigraphy in children with abnormalities of the bronchi, the lung and lung blood vessels].

Combined ventilation/perfusion scintigraphy with 133Xe/99mTc-HAM was performed within the framework of bronchological diagnostics in 38 children suffering from malformations of the bronchi, lungs and pulmonary vessels, and in 9 children after surgery of hernia of the diaphragm. The findings in stenoses, cysts in the bronchial system and in children with pulmonary vessel malformations, in one child with pulmonary agenesia and in a few other malformations, are presented. The significance of these findings in bronchological diagnosis in case of pulmonary malformations or clinical follow-up is discussed. Combined ventilation/perfusion scintigraphy is a valuable contribution to preliminary diagnosis and in follow-up of children with pulmonary malformations.
