Most often, it is caused by conditions that make blood clots more likely to form, including: Abnormal growth of cells in the bone marrow (myeloproliferative disorders). The most common cause is cirrhosis (chronic liver failure). In adults, an IVC collapsibility index of greater than 50% is associated with reduced right atrial pressure and severe dehydration, and indicates that the patient needs fluid therapy(23). eCollection 2022 Jul.
