Massive hemoptysis from a pulmonary sequestration controlled by embolization of aberrant pulmonary arteries: case report.

A case of massive hemoptysis due to pulmonary sequestration is presented. Initially, the diagnosis of sequestration was unsuspected and bronchial artery embolization was done for management of hemoptysis from the left lower lobe, but 4 days later massive hemoptysis recurred. Repeat arteriography, including a thoracoabdominal aortogram, revealed two large abdominal arteries penetrating the left diaphragm and feeding the lower lung. Embolization of the aberrant artery from the celiac trunk and the left inferior phrenic artery resulted in complete hemostasis until elective surgical ligation of the two arteries was performed 2 months later. The massive hemoptysis from a pulmonary sequestration could only be controlled after embolization of the transdiaphragmatic aberrant pulmonary arteries.
