Endovascular embolization of the complete type of anomalous systemic arterial supply to normal basal lung segments: a report of four cases and literature review.

The complete type of anomalous systemic arterial supply to normal basal lung segments is characterized by anomalous systemic artery supply to all or some of the normal basal segments with an absent corresponding pulmonary artery. Surgical intervention generally is required. This study reports on four patients with this anomaly with hemoptysis or a combination of other symptoms who underwent successful transarterial embolization using metallic coils or an Amplatzer vascular plug. To our knowledge, only six such cases treated with transarterial embolization have been reported previously in adult patients.
