Abnormal systemic-to-pulmonary-artery anastomoses can exist in many pathological conditions and result in a left-to-right shunt. Three such conditions are (a) congenital abnormalities, e.g., pulmonary vein atresia, (b) acquired states, e.g., chronic bronchiectasis, and (c) post-surgical states, e.g., a Mustard procedure for complete transposition. Regardless of the etiology, the anastomosis and resulting shunt produce increased oxygen saturation in the ipsilateral pulmonary artery. Four cases are presented, with emphasis on the angiographic and hemodynamic findings.
异常的体循环至肺动脉吻合可存在于多种病理状况中，并导致左向右分流。三种此类情况为：（a）先天性异常，如肺静脉闭锁；（b）后天性状态，如慢性支气管扩张；以及（c）术后状态，如用于完全性大动脉转位的Mustard手术。无论病因如何，吻合及由此产生的分流会使同侧肺动脉的氧饱和度增加。本文介绍了4例病例，重点关注血管造影和血流动力学表现。
