title: [Intralobar pulmonary sequestration with an aberrant artery originating from the celiac artery and communicating with the pulmonary artery].
abstract: A 13-year-old boy underwent a right lower lobectomy for removal of an intralobar pulmonary sequestrum with a very rare type of aberrant artery. The aberrant artery originated from the celiac artery and communicated with the pulmonary artery. Angiographic and histologic findings led us to the following hypothesis regarding the origin of the sequestrum in this patient: There was a hypoplastic bronchus and an aberrant artery that originated from the celiac artery. Infection caused obstruction of the hypoplastic bronchus, which resulted in formation of the sequestrum. Another possibility is that high systemic pressure in the aberrant artery caused destruction of alveoli and led to the formation of cysts in the lung and to sequestration. Finally, the aberrant artery and the pulmonary artery communicated due to chronic inflammation in the sequestrum.
