Summary
A rare hepatic arteriovenous malformation (HAVM) caused neonatal calf mortality. This condition, characterized by abnormal blood vessel connections in the liver, led to fatal internal bleeding.
Area of Science:
- Veterinary Pathology
- Comparative Medicine
- Vascular Malformations
Background:
- Hepatic arteriovenous malformations (HAVMs) are uncommon vascular anomalies.
- HAVMs have not been previously documented in cattle.
- Neonatal mortality in calves can stem from various causes, including internal hemorrhage.
