Thrombosis may be due to:

• Endothelial injury.
• Altered blood flow E.g. abnormal stasis.
• Hypercoagulability.

Often associated with other disease processes for example Disseminated intravascular coagulation.

Commonly see posterior paralysis of cats with cardiomyopathy.

Spontaneous venous thrombosis is rare. Seen in cattle with traumatic reticulo-peritonitis in the caudal vena cava.
