Abstract
16 children presenting with severe viral pneumonia sequelae (VPS) were explored with digital subtraction angiography (DSA) in the last 3 years. The clinical patterns were severe recurrent episodes of wheezing, significant dyspnea on exertion and/or productive cough. In all patients the initial episode of viral infection could be recognized. The age range was 18 months to 17 years and only the 3 younger patients were sedated for the procedure. The contrast medium injection was performed peripherally via a large vein. Nc complication was observed except one mild episode of wheezing after contrast injection. In all cases DSA showed perfusion defects which were peripheral. These anomalies were multiple in 14 cases, bilateral in 10 and unilateral in 4. In only 2 cases the defect was localized in one lobe. The proximal pulmonary arteries were always well seen, and of smaller size in the more affected lung in 5 cases. Correlations with isotopic studies were consistent, but DSA gave more information by demonstrating pulmonary vessels. Thus DSA, that is non aggressive procedure, seems to be very valuable in the investigation of VPS. DSA displays an angiographic pattern that is strongly suggestive of this diagnosis. Moreover it has a pronostic value as it precises very accurately the extension of parenchymal lesions.
