Therapeutic embolization of a systemic arterialization of lung without sequestration.
We report the case of a 51-year-old man with massive haemoptysis due to a systemic arterialization of lung without sequestration. Unlike bronchopulmonary sequestration there was a normal bronchial distribution and the involved lung parenchyma was normal. Therefore a therapeutic transarterial embolization of the aberrant systemic vessel from the distal thoracic aorta was performed. The embolization was successful and the patient did not suffer from further haemoptysis during the subsequent follow-up of ten months. A postembolization aortogram 6 months later demonstrated a complete occlusion of the embolized aberrant artery; in the lung perfusion scan there was only a small perfusion defect, but normal ventilation in the embolized basal part of the left lower lobe. Our case represents an alternative treatment to surgery for this rare anomaly.
