Prenatal Diagnosis of Aberrant Right Subclavian Artery: A Case Report and Review of Literature
產前診斷右側異生性鎖骨下動脈：案例報告及文獻回顧
摘要
Aberrant right subclavian artery (ARSA) is a rare congenital aortic arch anomaly that can be detected prenatally using the three-vessels and trachea (3VT) view during routine ultrasound and power Doppler ultrasound. Here, we report a case of prenatal diagnosis of ARSA in a singleton pregnancy with normal karyotype during the second trimester. Detection of ARSA should be followed up with a detailed ultrasound examination for other cardiac defects or ultrasound markers. Chromosomal investigation is advisable due to the increased positive likelihood ratio (LR) for aneuploidy.

右側異生性鎖骨下動脈是一種少見之主動脈弓發育異常，可以藉由高層次超音波結合彩色杜卜勒超音波於胎兒心臟三血管及氣管切面的異常成像達成產前診斷。我們報告一位於第二孕期發現羊水染色體正常合併右側異生性鎖骨下動脈之產前診斷個案。根據文獻回顧，右側異生性鎖骨下動脈常合併其他先天性心臟結構異常或超音波異常，而且合併染色體異常的機率也會增加。
