title: Acute right ventricular failure in a patient with hepatic cirrhosis.
abstract: Pulmonary embolic disease is most commonly a manifestation of venous thromboembolism (VTE). However, fat, tumor, and air may all embolize to the pulmonary vasculature and lymphatics resulting in various clinical manifestations. Tumor emboli to small pulmonary vessels and lymphatics can lead to hypoxemic respiratory failure and shock. We present a 62-year-old male with history of mild COPD and end-stage liver disease secondary to hepatitis C admitted due to progressive shortness of breath and hypoxemia who developed shock and right ventricular failure. After a negative evaluation for venous thromboembolic disease, he had progressive respiratory and hemodynamic deterioration despite mechanical ventilation, renal replacement therapy, and vasopressive/inotropic support. Postmortem examination revealed diffuse micronodular moderately differentiated hepatocellular carcinoma (HCC) without a discrete mass, as well as numerous HCC tumor emboli to the lung and focally to the heart, consistent with disseminated hepatocellular tumor microembolism.
