Peripheral vascular disease in the horse covers disorders of arteries, veins and lymphatics outside the heart. The NAVLE favours four patterns: exercise-induced hindlimb weakness (aorto-iliac thrombosis), a swollen, firm jugular vein after catheterization, acute limb edema with petechiae after strangles (purpura hemorrhagica), and colic from migrating Strongylus vulgaris larvae.
Key facts
Peripheral vascular disease at a glance- Species and system: horse; cardiovascular, hemolymphatic.
- Arterial: aorto-iliac thrombosis (terminal aorta and proximal iliac arteries); verminous arteritis from S. vulgaris larvae.
- Venous: jugular thrombophlebitis, usually after IV injection or catheterization.
- Immune-mediated: purpura hemorrhagica, a necrotizing vasculitis after exposure to Streptococcus equi subsp. equi.
- Zoonotic or reportable: none of these; equine viral arteritis is reportable in many places (check local rules).
