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.
一名13岁男孩接受了右下肺叶切除术，以切除一个叶内型肺隔离症，该肺隔离症伴有一种非常罕见的异常动脉类型。这条异常动脉起源于腹腔干，并与肺动脉相通。血管造影和组织学检查结果使我们对该患者肺隔离症的起源提出了以下假设：存在一个发育不全的支气管和一条起源于腹腔干的异常动脉。感染导致发育不全的支气管阻塞，进而导致肺隔离症的形成。另一种可能性是，异常动脉中的高体循环压力导致肺泡破坏，从而导致肺部囊肿形成和肺隔离。最后，由于肺隔离症中的慢性炎症，异常动脉与肺动脉相通。
