Summary
Rare venous anomalies, including a persistent left superior vena cava and anomalous left hepatic vein, can complicate cardiac procedures. This case highlights their diagnosis and management in a 67-year-old woman.
Area of Science:
- Cardiology
- Vascular Surgery
- Embryology
Background:
- Congenital anomalies of the venous system, such as those involving the inferior vena cava (IVC), are uncommon.
- These anomalies can present diagnostic and therapeutic challenges in cardiac procedures.
- A persistent left superior vena cava (PLSVC) is one such anomaly.
Observation:
- A 67-year-old woman presented with a complex venous anomaly.
- This included an interrupted left IVC draining into the hemiazygos vein system, a PLSVC, and an anomalous left hepatic vein (LHV) draining into the coronary sinus (CS).
- These anomalies led to a coronary sinus aneurysm.
Findings:
- Echocardiography effectively diagnosed the coronary sinus anomaly and aneurysm.
- Contrast-enhanced computed tomography provided a detailed anatomical map of the complex venous malformations.
- Surgical coronary artery bypass graft confirmed the diagnosis and was successfully performed.
Implications:
- Echocardiography is valuable for diagnosing coronary sinus anomalies and aneurysms.
- Congenital venous anomalies often stem from embryonic developmental errors.
- Advanced imaging like CT is crucial for understanding the full extent of these rare vascular variations.
