Insights
Persistent left superior vena cava (PLSVC) is a common thoracic venous anomaly that can complicate central venous catheter placement. Understanding PLSVC anatomy is crucial for interventional nephrologists to avoid diagnostic and procedural challenges.
Area of Science:
- Vascular anatomy
- Thoracic venous anomalies
- Interventional nephrology
Background:
- Central venous catheter placement is a frequent procedure in interventional nephrology.
- Anatomic variations of great vessels in the neck and chest require careful consideration.
- Persistent left superior vena cava (PLSVC) is the most prevalent thoracic venous anomaly.
Observation:
- Two cases of persistent left superior vena cava (PLSVC) are presented.
- PLSVC can lead to difficulties during catheterization of internal jugular or subclavian veins.
- This anomaly may also create diagnostic challenges for clinicians.
Findings:
- Persistent left superior vena cava (PLSVC) occurs in 0.3-0.5% of the population.
- Recognition of PLSVC is vital for successful central venous access.
- PLSVC can mimic other conditions or complicate interpretations of diagnostic imaging.
Implications:
- Awareness of PLSVC aids in preventing complications during central venous catheterization.
- Accurate diagnosis of PLSVC is essential for patient safety and effective treatment.
- Further research into managing patients with PLSVC may improve procedural outcomes.
Abstract:
Awareness and recognition of anatomic anomalies of the great vessels of the neck and chest are important for the interventional nephrologist, as central venous catheter placement is a common procedure. A persistent left superior vena cava (PLSVC) is the most common thoracic venous anomaly (0.3-0.5% of the population), and can present difficulty during internal jugular or subclavian vein catheter insertion, as well as pose a diagnostic dilemma. In this report, two cases of PLSVC are described, and the clinical significance and diagnosis of PLSVC are reviewed.
