Pulmonary tumor thrombotic microangiopathy: Exploration into current diagnostic aids and therapeutics

Abstract

Abstract Pulmonary tumor thrombotic microangiopathy (PTTM) is an under‐recognized cause of pulmonary hypertension and fulminant right ventricle failure. It is associated with a high mortality due to delay in diagnosis. We present two cases of PTTM, both diagnosed postmortem, highlighting the importance of timely identification and initiation of treatment for this near‐fatal condition.
