Summary
Saccular superior vena cava aneurysms (SVCAs) are rare mediastinal masses. This report details the diagnosis and surgical treatment of an SVCA using cardiopulmonary bypass and pericardial patch reconstruction.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Saccular superior vena cava aneurysms (SVCAs) are exceptionally rare mediastinal masses, with fewer than 30 cases reported in medical literature.
- Diagnosis and treatment present unique challenges due to their rarity.
Observation:
- A case of saccular superior vena cava aneurysm is presented.
- The aneurysm was surgically resected via median sternotomy.
Findings:
- The surgical procedure required cardiopulmonary bypass.
- Superior vena cava reconstruction was successfully performed using a bovine pericardial patch.
Implications:
- This case highlights a successful surgical approach for managing rare SVCAs.
- The presented protocol offers valuable insights for treating similar mediastinal vascular abnormalities.
