Insights
A persistent left superior vena cava caused cyanosis in a patient with complex heart disease. Occluding this vessel with a vena cava filter successfully treated the condition.
Area of Science:
- Cardiology
- Vascular Surgery
- Medical Device Technology
Background:
- Complex cyanotic heart disease and pulmonary hypertension can lead to significant patient morbidity.
- A persistent left superior vena cava (PLSVC) draining into an unroofed coronary sinus is a rare anomaly that can cause cyanosis.
- Accurate diagnosis and effective intervention are crucial for managing such complex cardiac conditions.
Observation:
- A 48-year-old female presented with partial cyanosis attributed to a PLSVC.
- The PLSVC measured 22 mm in diameter and drained into an unroofed coronary sinus.
- This anatomical variation resulted in right-to-left shunting, exacerbating her cyanotic heart disease.
Findings:
- The PLSVC was successfully occluded using a Günther Tulip Vena Cava Mreye Filter.
- The filter served as a barrier, enabling the effective use of embolisation coils to close the anomalous vessel.
- This percutaneous intervention resolved the abnormal venous drainage and corrected the cyanosis.
Implications:
- Percutaneous occlusion of PLSVC using vena cava filters is a viable treatment option.
- This approach offers a minimally invasive alternative for managing cyanosis caused by anomalous venous connections.
- Successful intervention can significantly improve the quality of life for patients with complex congenital heart disease and rare venous anomalies.
Abstract:
A 48 year old female with complex cyanotic heart disease and pulmonary hypertension was partly cyanosed because of a persistent left superior vena cava draining into an unroofed coronary sinus. The left superior vena cava, which measured 22 mm in diameter, was successfully occluded with a Günther Tulip Vena Cava Mreye Filter which acted as a barrier for embolisation coils.
