Aneurysm in Horses

An aneurysm is caused by an abnormal ballooning of a weakened arterial wall in the body. If the ballooning becomes big enough, it will burst, leading to massive hemorrhaging and death. An aneurysm has few warning signs, so most horses die of the condition before it is diagnosed.

Symptoms and Types

Collapse Mucous membranes of the mouth, nose, eyes, rectum, and genitalia become very pale Causes Presence of parasites Red worm larvae (strongylus vulgaris)

Diagnosis

Diagnosis is usually made post mortem (after death). There are few warning signs of an aneurysm, and once it bursts, the horse cannot survive.
