Unusual Course of a Pulmonary Artery Catheter Due to Absence of Right Superior Vena Cava.

Abstract

The persistent left superior vena cava may complicate the placement of vascular access. It rarely occurs with an absence of the right superior vena cava. We present a chest X-ray of a patient with this rare anomaly that was demonstrated incidentally with an unusual course of a pulmonary artery catheter course.
