Persistent left superior vena cava (PLSVC) is a rare congenital vascular anomaly. This case report details the first documented instance of PLSVC in sheep, confirmed via angiography.

Area of Science:

  • Veterinary Anatomy
  • Cardiovascular Research
  • Comparative Medicine

Background:

  • Persistent left superior vena cava (PLSVC) is an uncommon congenital vascular anomaly.
  • Understanding variations in great vessel anatomy is crucial for comparative cardiovascular studies.
  • Sheep are increasingly utilized as models in biomedical research.

Observation:

  • A rare case of persistent left superior vena cava (PLSVC) was identified in a sheep.
  • The anomaly was visualized and confirmed using diagnostic angiography.
  • This represents a novel finding within ovine cardiovascular anatomy.

Findings:

  • Angiographic evidence confirmed the presence of PLSVC in the sheep.
  • This is the first documented report of PLSVC in the ovine species.

  • The anatomical variant did not appear to cause immediate clinical complications in this individual.

    • Implications:

    • This finding expands the known spectrum of cardiovascular variations in domestic animals.
    • Awareness of PLSVC in sheep is important for researchers and clinicians using this model.
    • Further studies may explore the prevalence and clinical significance of PLSVC in sheep populations.
