Summary
The bovine aortic arch, a variant with two aortic branches, occurred in 4.8% of fetuses studied. This prevalence was lower than in adults and showed no clear association with fetal anomalies in this cohort.
Area of Science:
- Medical Imaging
- Fetal Anatomy
- Cardiovascular Development
Background:
- The bovine aortic arch is a common aortic arch branching variant, characterized by two primary branches originating from the aorta.
- Previous studies report varying prevalence rates in adult and fetal populations, necessitating further investigation into its occurrence during fetal development.
Purpose of the Study:
- To determine the prevalence of the bovine aortic arch variant in a fetal population.
- To assess the association between the bovine aortic arch and concomitant fetal anomalies.
Main Methods:
- Retrospective analysis of 417 fetuses (15-40 weeks gestation).
- Data collected via fetal echocardiography and/or ultrasonography.
- Branching patterns and presence of fetal anomalies were recorded.
Main Results:
- A bovine aortic arch was identified in 4.8% of fetuses.
- The prevalence was 4.5% in fetuses without anomalies and 7.8% in those with minor anomalies.
- No bovine aortic arch was observed in fetuses with major anomalies.
Conclusions:
- The prevalence of bovine aortic arch in fetuses is lower than previously reported in adults, potentially due to population differences.
- This study suggests the bovine aortic arch may not be strongly associated with fetal anomalies, though further research is needed.

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

01:10The Arch of Aorta
1.5K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:25Abdominal Aorta
2.0K
Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.

01:07Development of Blood Vessels
1.3K
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

1.4K
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
