Abstract:
We present the technical details of en bloc resection and extended replacement of an infected aortic arch. A 74-year-old man underwent emergent surgery under a diagnosis of impending rupture of an infected aortic arch aneurysm. The patient's chest was entered through a median sternotomy with a left thoracotomy at the fourth intercostal space. After dissection of the left phrenic and left recurrent nerves, the infected aortic arch was widely excised en bloc under circulatory arrest with selective cerebral perfusion. It was replaced with a rifampicin-bonded prosthetic graft. The prosthesis and anastomoses were covered with a harvested omental flap. Although an appropriate approach and supportive therapy are indispensable, en bloc resection of the infected tissue is an important technique when treating infected aortic aneurysms.
Insights
En bloc resection and replacement with a rifampicin-bonded graft is a key technique for infected aortic arch aneurysms. This surgical approach addresses impending rupture, improving patient outcomes in complex cases.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Infectious Disease Management
Background:
- Infected aortic arch aneurysms pose a critical surgical challenge due to rupture risk.
- Emergent surgical intervention is often required for hemodynamic instability.
Observation:
- A 74-year-old male presented with an infected aortic arch aneurysm at risk of rupture.
- The surgical approach involved median sternotomy and left thoracotomy.
Findings:
- En bloc resection of the infected aortic arch was performed under circulatory arrest with selective cerebral perfusion.
- Replacement utilized a rifampicin-bonded prosthetic graft, with omental flap coverage for the prosthesis and anastomoses.
Implications:
- En bloc resection is a crucial technique for managing infected aortic aneurysms.
- Rifampicin-bonded grafts may reduce the risk of graft infection.
- This approach highlights the importance of specialized techniques in complex aortic pathology.
