caval syndrome

syndrome caused by the presence of large number of heartworms (Dirofilaria immitis) in the posterior vena cava which may lead to the sudden onset of signs of hemolytic anemia and liver failure, often without preceding cardiopulmonary signs. Disseminated intravascular coagulopathy is a common complication and the mortality rate is high. Called also vena caval syndrome.
