Insights
Redo cardiac surgery for ascending aortic aneurysms is common. Pre-operative imaging, like computed tomography scans, aids in safely planning complex aortic aneurysm replacement in patients with prior coronary artery bypass grafting and mediastinitis.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Redo cardiac surgery is frequently performed.
- Ascending aortic aneurysms require surgical intervention.
- Previous coronary artery bypass grafting (CABG) presents unique challenges.
Observation:
- A patient with a patent left internal thoracic artery (LITA) graft to the left anterior descending (LAD) artery underwent redo cardiac surgery.
- The patient required ascending aorta aneurysm replacement.
- The patient had a history of mediastinitis.
Findings:
- A 64-slice computed tomographic (CT) scan was utilized for pre-operative planning.
- The CT scan facilitated a safe surgical approach for ascending aorta replacement.
- Successful management of a complex redo cardiac surgery case was achieved.
Implications:
- Pre-operative CT imaging is crucial for planning complex redo cardiac surgeries.
- Advanced imaging improves safety and outcomes in patients with prior CABG and mediastinitis.
- This case highlights the importance of tailored surgical strategies in redo cardiac procedures.
Abstract:
Redo cardiac surgery is commonly performed in the current era. We describe a clinical scenario in a patient with a patent left internal thoracic artery to left anterior descending artery graft, requiring replacement of ascending aortic aneurysm with previous coronary artery bypass operation complicated by mediastinitis. A pre-operative 64 slice computed tomographic scan helped us plan and perform replacement of ascending aorta safely.
