Summary
Aortic aneurysm repair using a ringed graft led to late dislodgement and fatal bleeding. The graft
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Medical Device Complications
Background:
- A 70-year-old male patient underwent distal aortic arch replacement for a large aneurysm.
- A ringed graft was utilized for the aortic arch repair.
Observation:
- The patient experienced sudden hemoptysis (bloody cough) 54 months post-operation.
- Autopsy revealed dislodgement of the graft's posterior spool from the aorta.
Findings:
- Histologic examination of the dislodged graft showed severe damage to the intima and media's elastic fibers.
- Minimal histologic changes were noted at the anterior anastomotic site.
Implications:
- Late graft dislodgement, potentially due to a long, kinked graft, can cause catastrophic complications.
- This case highlights the importance of graft configuration and long-term surveillance after aortic aneurysm repair.
