Objective “Bovine aortic arch” is the second most common variant of aortic arch branching, in which only two branches originate directly from the aorta. The prevalence of this condition has been reported in different studies to be around 6% in human fetuses and 11‐27% in the adult population. In this study, we describe the prevalence of bovine aortic arch in fetuses, and assess the prevalence of concomitant fetal anomalies. Methods A retrospective analysis of 417 fetuses between 15‐40 weeks of gestation. Data regarding branching of the fetal aortic arch and other fetal anomalies were collected by fetal echocardiography and/or fetal ultrasonography. Results A bovine arch was found in 20/413 fetuses (4.8%, 95CI 3.1‐7.3%), of whom 14/310 (4.5%) had no fetal anomalies, and 6/77 (7.8%) exhibited minor changes (P = .241). None of the 26 fetuses with major anomalies had a bovine arch. Conclusion Fetuses in this study had a lower prevalence of bovine aortic arch than that previously reported in adults, most probably due to differences in the population examined. This study was underpowered to determine that bovine arch is a common anatomic variant, and is not associated with fetal anomalies.

“…The vast majority provided data from surgery or radiologic intervention in adults for stenting or valve repair and problems encountered whenever anatomic variants were present, associated with aortic dissection and associated pulmonary and cerebral embolism. Only three reported prenatal cases or studies on prenatal series [14,16,17] and one abstract [18] (Table 2 and Figure 7) all the 3 papers were written in English; 127 items referred to veterinary studies.…”

Prenatal Diagnosis of Bovine Aortic Arch Anatomic Variant

et al. 2022

Fetal aortic arch development is an early and complex process that depends on many genetic and environmental factors. The final aortic arch varies greatly; it may take the form of a normal arch, anatomic variant (AAAV) with a common origin to that of the innominate artery and left common carotid artery (formerly known as “bovine aortic arch” (with an incidence of up to 27%)) or one of multiple pathological conditions. The present study aimed to establish the feasibility and impact of prenatal anatomic arch variants’ diagnosis. A retrospective study of 271 fetal second- and third-trimester anomaly scans was performed in our tertiary center. Examinations that evaluated the sagittal aortic arch were included and the branching pattern was assessed. Additionally, a literature data search based on the terms “common origin of innominate artery and left common carotid artery”, “bovine arch”, “bovine aortic” and “aortic arch anomalies” was performed. Results that referred to prenatal AAAV were retained and the papers evaluated. In our study, the AAA incidence was 1.93%, with 4 out of 5 cases being arch type B. All cases had minor associated conditions but a good postnatal outcome. An anatomic aortic variant with a common IA and LCCa prenatal diagnosis was found in a small number of studies; most of the cases described in pediatric and adult series were related to cardiac surgery for stenting, aneurysm or thoracic-associated diseases. The incidence of AAAV varied from 6 to 27% depending on the population studied (highest incidence in African individuals). The variant was highly associated with aortic dissection, pulmonary and cerebral embolism and increased risks of incidents during surgery. Diagnosing AAAV during a routine anatomic scan is feasible and diagnoses can be made when anomaly scans are performed. Awareness of the condition is important for postnatal surgery when other cardiac anomalies are found; this can prevent accidents with simple changes to the patient’s lifestyle, and, in the case of surgery, means we can adopt the correct surgical approach.

“…A bovine-type aortic arch is the most common variant of aortic arch (7.2%-21.1%). 5 It refers to a common LCCA and BA origin from the aortic arch. It probably occurs due to rightward migration of the left third aortic arch and eventual derivation of the bovine trunk and BA from the right horn of aortic sac (Figure 3).…”
