[A case of intralobar pulmonary sequestration associated with abnormal connection between the aberrant artery and the pulmonary artery]

Abstract

The patient was a 5-year-old girl and had a history of recurrent pneumonia. Angiogram demonstrated that the aberrant arteries arising from descending aorta communicated with left pulmonary A10 where the multi-lobulated cystic lesion was seen by chest X-P. The right heart catheterization revealed the step-up of oxygen saturation in distal part of left pulmonary artery A10. Diagnosis was the intralobar pulmonary sequestration with the aberrant arteries communicating with pulmonary artery. The connection between aberrant arteries and pulmonary artery in this case might be caused by the chronic inflammation in the sequestrated lung. We found 4 case reports in which the communication between aberrant arteries and pulmonary artery was evident.
