    Area of Science:

    • Veterinary Pathology
    • Comparative Anatomy
    • Developmental Biology

    Background:

    • Congenital vascular anomalies, such as a right aortic arch, can occur in various animal species.
    • Understanding the embryological development of the aortic arch is crucial for identifying potential causes of malformations.

    Purpose of the Study:

    • To describe the necropsy findings of a right aortic arch in a lamb and mini-pigs.
    • To discuss the pathogenesis and developmental origins of this vascular pattern.

    Main Methods:

    • Necropsy examination of a lamb, a mini-pig fetus, and a mini-pig.
    • Gross pathological description of the aortic arch and associated vessels.
    • Comparative analysis of the vascular anatomy.

    Main Results:

    • Detailed description of the right aortic arch anatomy in the examined specimens.
    • Identification of the specific vascular pattern associated with the anomaly.
    • Discussion of potential deviations during embryonic development leading to this condition.

    Conclusions:

    • The right aortic arch is a notable congenital vascular anomaly that can occur in domestic animals.
    • Pathogenesis likely involves aberrant development of embryonic aortic arches.
    • These findings contribute to the understanding of cardiovascular malformations in veterinary medicine.
