===Description===
Thrombosis is a localized or generalized intravascular clot formation. Thrombi form as the result of trauma or pathological processes affecting the blood vessel endothelium or disturbances to blood flow and/or blood composition. Some diseases such as infective endocarditis and heart worm increase the risk of thrombi formation.
===Diagnosis===
====History & Clinical Signs====
*Signs depend on the area affected and the size of the blocked vessel.
*Poor perfusion below affected area.
*Malfunction and necrosis of affected organs
====Laboratory Findings====
Abnormalities associated with lack of blood perfusion and/or pathological conditions.
====Ultrasonography====
*Blood stasis
*Visualization of a thrombus
====Angiography====
*May show lack of opacity in affected region
===Treatment===
-Treat underlying problem
-IV Fluids
-Anticoagulant (Heparin for short term treatment, Aspirin for long term treatment)
===Prognosis===
-Depends on underlying condition
