Central venous access through a persistent left superior vena cava: a case series.

Area of Science:

• Cardiology
• Vascular Surgery
• Congenital Anomalies

Background:

• Persistent left superior vena cava (PLSVC) is a rare congenital anomaly often discovered during central venous access procedures.
• While most PLSVCs drain into the right atrium, drainage into the left atrium poses risks for systemic emboli dispersion.
• Potential complications include cardiac dysrhythmias, venous stenosis, and thrombosis.

Observation:

• This case review examines three patients requiring long-term central venous access for chemotherapy and hemodialysis.
• The cases illustrate the successful utilization of PLSVC for central venous access.
• Diagnostic imaging modalities like venography, echocardiography, and CT scans are crucial for determining drainage patterns.

Findings:

• Persistent left superior vena cava can be safely utilized for long-term central venous access.
• Accurate assessment of PLSVC drainage patterns is critical before catheterization.
• The reviewed cases demonstrate successful outcomes in patients undergoing chemotherapy and hemodialysis.

Implications:

• Recognizing and understanding PLSVC anatomy is vital for safe central venous catheterization.
• PLSVC can serve as a viable conduit for long-term venous access, challenging previous assumptions.
• Further research into managing PLSVC anomalies can improve patient care and procedural safety.
