The authors examined whether the drug helped reduce a variety of pregnancy complications as a whole, rather than scrutinizing its effects
on venous thromboembolism, preeclampsia and other problems individually.
The thrombus can be classified based
on its location and the clinical signs it produces (eg, jugular
venous thrombosis in large animals associated with prolonged
venous catheterization, pulmonary arterial
thromboembolism associated with heartworm disease in dogs).
