Abstract:
:Infection, thrombosis, and catheter dislodgment are well-recognized potential complications of chronic intravenous prostanoid therapy for pulmonary arterial hypertension. As long-term outcomes of pulmonary hypertension patients improve, novel adverse events are likely to arise. We describe the sudden development of unexplained hypotension and lightheadedness in a patient receiving intravenous epoprostenol for several years, ultimately determined to be due to an unusual catheter complication, not previously described in this population.
