THERAPEUTIC EMBOLIZATION OF A PULMONARY A RTERIOVENOUS-FISTULA IN A CHILD

Background. - Pulmonary arteriovenous fistula is a rare vascular abnor mality in children that is usually treated by lobectomy. This report d escribes a case that was improved by coil embolization. Case report. - A thoracic X-ray was routinely taken before anygdalectomy in a 6 year -old girl. It showed a consolidation area in the left superior lobe th at persisted despite treatment with erythromycin for 3 weeks. Bronchos copy was normal, but study of blood gases showed a refractory hypoxemi a cyanosis and hemoglobin at 16/2 g/dl. Right-heat catheterization and angiography showed a pulmonary arteriovenous fistula that was treated by coil embolization. A control investigation 3 months later showed n ormal arterial oxygen saturation, hemoglobin at 14.5 g/dl and reduced pulmonary condensation. Conclusion. - Pulmonary arteriovenous fistula may show few symptoms. Coil embolization appears to be a useful initia l non-aggressive treatment.
