“…note that a ring may be secondary either to a contralateral descending aorta or an aberrant subclavian artery 1 . Isolated subclavian artery, a rare anomaly, has also been reported with a CAA and a coarctation 13 . The CAA in our patient was left sided with a left descending aorta and an aberrant right subclavian artery with no vascular ring.…”

“…1 Isolated subclavian artery, a rare anomaly, has also been reported with a CAA and a coarctation. 13 The CAA in our patient was left sided with a left descending aorta and an aberrant right subclavian artery with no vascular ring. However, there was a significant distance between the left carotid and the left subclavian artery-something that has been described in CAA when there is an associated coarctation or psuedocoarctation.…”

Cervical aortic arch (CAA) and retro-aortic innominate vein (RAIV) are rare entities which can be associated with one another in a structurally normal heart. Less well recognized is the fact, that a third entity may often be present as well, since aortic arch abnormalities are common in a CAA. Hence, these three entities (CAA, RAIV, and an arch anomaly -in this case a post-ductal coarctation) may present as a triad. We present the first prenatal diagnosis of this rare triad which can be explained by common embryological origins which are discussed along with instructive aspects in diagnosis and management.

“…Thus, the persistence or regression of the left or right sixth arch form the left, right, or bilateral DA patent. Shang et al (12) and Penslar et al (7) had found that the proximal part of the isolated artery has the same histological features as the DA prenatally. According to Edwards' theory, isolation is almost always seen on the side contralateral to the aortic arch position, which is the same with our results.…”

Background Isolated aortic brachiocephalic artery (IABA) is a rare congenital aortic arch anomaly. It is difficult to diagnose IABA prenatally and the prevalence in the prenatal population is unknown. Purpose To evaluate the echocardiographic characteristics and associations in fetuses with IABA. Material and Methods We retrospectively analyzed all cases of prenatal diagnosis of IABA from January 2012 to November 2020 and reviewed the follow-up results. Copy Number Variation Sequencing (CNV-Seq) was performed using the biological specimens of the of the fetuses and family members. Results Ten cases (10/45652, 0.022%) of IABA were identified in our center. The prevalence of the cases with isolated left subclavian artery (ILSCA) in the right aortic arch (RAA) population was 0.98% (6/613). The ILSCA was the most common isolated arch branch. All the isolated branches were on the opposite side of aortic arch in all the cases. The “ice stick” sign in the coronal section could be seen in most cases of IABA. Of the 10 cases, 8 (8/10, 80%) were associated with tetralogy of Fallot (TOF). Two cases of IABA were combined with 22q11.2 deletion syndrome. Conclusion IABA is a rare aortic anomaly. ILSCA was the most common isolated arch branch and TOF was the most common associated intra-cardiac anomaly. The “ice stick” sign in the coronal section could indicate a diagnosis of the IABA.

Prenatal ultrasound findings, genetic testing, and literature review of Isolated left subclavian artery

Background The occurrence of Isolated left subclavian artery (ILSA) is relatively rare, ILSA is caused by the persistence of the dorsal segment of the sixth left arch, with regression of the fourth arch artery and interruption of the left dorsal aorta at the distal end of the seventh intersegmental artery on the left side during embryonic development. The left subclavian artery is connected to the pulmonary artery through an arterial duct, which can be closed or unobstructed. This abnormality can lead to congenital subclavian steal syndrome and vertebrobasilar artery insufficiency. Case presentation We reported three fetuses with ILSA and intracardiac malformation. Among them, one case was suspected to be diagnosed with ILSA by echocardiography, while the other two cases were not diagnosed, but were accidentally discovered during autopsy. We have also conducted a literature review of its prenatal screening, diagnosis, management, and outcomes. Our three cases were tested by WES‐Trio (whole exome sequencing). Worldwide, the ILSA cases reported in English literature have not been detected by WES. And likely pathogenic results were found in our two cases. Although it could not explain the intracardiac malformation we found, it will help to explore the etiology in the future. Conclusions Prenatal echocardiography detection and diagnosis of ILSA is a new challenge, which has different effects on the prognosis of the fetus. When finding intracardiac malformation with right aortic arch, we need to perform an unconventional view of ultrasound scanning and combine with CDFI to find the origin of the left subclavian artery. Although we cannot find the cause of the disease temporarily, but our genetic results can help prenatal genetic counseling.
