Bedside confirmation of a persistent left superior vena cava based on aberrantly positioned central venous catheter on chest radiograph.
This is a report of incidental diagnosis of a persistent left superior vena cava (PLSVC) based on an abnormal positioning of central venous catheter seen on chest radiograph and an abnormal pressure waveform. Non-invasive bedside tests included venography with simultaneous chest radiograph and a transthoracic echocardiography with an agitated saline microbubble contrast. These tests led to the diagnosis of PLSVC. Although PLSVC is the most common venous thoracic anomaly that produces a diagnostic dilemma, not many anaesthetists and intensivists are familiar with its appearance, diagnosis and implications. The clinical significance of PLSVC and diagnostic options are discussed.
