Summary
A rare retrocardiac arteriovenous malformation caused recurrent cerebral embolisms for nearly a decade. Surgical resection and vein reconstruction successfully eliminated the source, preventing further cerebrovascular events.
Area of Science:
- Cardiovascular Surgery
- Neurology
- Vascular Malformations
Background:
- Recurrent cerebral embolizations pose significant long-term risks.
- Identifying the precise source of emboli is crucial for effective treatment.
- Complex vascular anomalies require tailored surgical approaches.
Observation:
- A 28-year-old female patient presented with a 9-year history of recurrent cerebral embolizations.
- A retrocardiac arteriovenous malformation (AVM) was identified as the embolic source.
- The AVM received blood supply from chest wall veins, the right upper pulmonary vein, and an aberrant hepatic vein.
Findings:
- Surgical resection of the retrocardiac AVM was performed.
- All feeding veins, including those from the chest wall and pulmonary circulation, were ligated.
- The aberrant hepatic vein was reimplanted into the right atrium.
Implications:
- Successful surgical management of complex AVMs can prevent devastating neurological events.
- This case highlights the importance of thorough vascular imaging to diagnose rare anomalies.
- The described surgical technique offers a potential solution for similar complex vascular malformations.
