| Summary: | Persistent left superior vena cava (PLSVC) is a rare congenital, thoracic, and vascular anomaly.
Although PLSVCs generally do not have a hemodynamic effect, several types of PLSVC and
some cardiac anomalies may manifest with clinical symptoms. The presence of PLSVC can render
catheterization via left subclavian access difficult when placing a pacemaker or central venous
catheter. As such, recognizing a PLSVC that is typically incidentally discovered can prevent
complications such as vascular injury. Differentiating vessels found in a similar location as PLSVC
is necessary when performing thoracic vascular procedures. This pictorial essay explains the
multi-detector CT findings of a PLSVC, and provides a summary of other blood vessels that require
differentiation during thoracic vascular procedures. |
