Insights
A 68-year-old male underwent successful surgical repair of an intrathoracic left subclavian artery aneurysm. The procedure involved resection and reconstruction with a Dacron graft, with no complications.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Thoracic Surgery
Background:
- Intrathoracic aneurysms of the subclavian artery are rare vascular conditions.
- Surgical management requires careful pre-operative assessment and precise surgical technique.
Observation:
- A case report of a 68-year-old male with an aneurysm of the proximal left subclavian artery (LSA) is presented.
- Diagnostic imaging included chest CT and angiography, confirming the LSA aneurysm.
- Intraoperative direct echography assessed the intima of the distal aortic arch and LSA.
Findings:
- The distal aortic arch and LSA intima showed no calcification or mural thrombi.
- Surgical resection of the LSA aneurysm was performed using partial cardiopulmonary bypass.
- The LSA was reconstructed with an 8 mm knitted Dacron graft after direct suture closure of its orifice.
Implications:
- This case highlights a successful surgical approach for treating intrathoracic left subclavian artery aneurysms.
- The technique described offers a viable option for managing similar vascular pathologies.
- Early diagnosis and tailored surgical intervention are crucial for favorable outcomes in LSA aneurysm cases.
Abstract:
A case of intrathoracic aneurysm of the left subclavian artery is reported. The case was 68-year-old male. Chest CT and angiography revealed an aneurysm of left subclavian artery (LSA) located the proximal portion of LSA. The chest was opened by fourth intercostal thoracotomy. We evaluated the intima of distal aortic arch and LSA by introperative direct echography using a small probe (finger tip size). Since there was no calcification or mural thrombi at the distal aortic arch, the aneurysm was resected using partial cardiopulmonary bypass and the orifice of LSA was closed direct suture. LSA was reconstructed with knitted Dacron graft (8 mm). Postoperative course was uneventful.
