Total aortic arch replacement by a cryopreserved aortic homograft
1Department of Cardio-Vascular Surgery, Hospital N. S. del Pino, Las Palmas de Gran Canaria, Spain.
Summary
This study reports the first complete aortic arch substitution using a cryopreserved human aorta homograft in a patient with a pseudoaneurysm. The successful surgical intervention restored aortic integrity and patient health.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Aortic arch pseudoaneurysms pose significant surgical challenges, particularly after prior interventions.
- Hemoptysis and potential contamination necessitate complex reconstructive strategies.
Observation:
- A 60-year-old male presented with a pseudoaneurysm of the aortic arch and hemoptysis following previous transverse aorta surgery.
- Surgical intervention involved cardiopulmonary bypass, cerebral perfusion, aortic arch resection, and reconstruction.
Findings:
- A complete aortic arch substitution was achieved using a cryopreserved human aorta homograft.
- The supra-aortic trunks were successfully re-anastomosed to the allograft.
- A bronchial fistula was repaired using a native aortic arch flap.
- The patient remained asymptomatic two months post-operation.
Implications:
- Cryopreserved aortic homografts represent a viable option for complex aortic arch reconstructions, especially in contaminated fields.
- This technique may be applicable to other conditions like infected aneurysms and aorto-enteric fistulas.
- This case highlights a novel approach to aortic arch replacement, potentially expanding treatment options for challenging pathologies.
