Hypothesis
What are the implications and diagnostic approaches for persistent left superior vena cava (PLSVC)?
Conclusion
The presence of a dilated coronary sinus on echocardiography should alert clinicians to the possibility of PLSVC.
Supporting Evidence
- PLSVC is the most common congenital thoracic venous anomaly with a prevalence of 0.3–0.5%.
- Diagnosis is often made incidentally during imaging for unrelated issues.
- PLSVC can complicate catheter placements, especially via the left subclavian approach.
- Associated cardiac anomalies are found in almost 40% of patients with PLSVC.
Takeaway
Sometimes, people have a special vein called a persistent left superior vena cava that can make it tricky for doctors to put in catheters. If they see a big space in the heart on an ultrasound, they should think about this special vein.
Methodology
The case was diagnosed using echocardiography and confirmed with a follow-up CT scan.
Limitations
The study is based on a single case report, which may not represent the broader population.
Participant Demographics
A 19-year-old male patient.
