Summary
A rare complication of carotid endarterectomy using saphenous vein grafts is aseptic necrosis and rupture of the vein patch. This can lead to stroke or death, particularly with small diameter veins from the ankle.
Area of Science:
- Vascular Surgery
- Surgical Complications
Background:
- Carotid endarterectomy aims to prevent stroke by removing plaque from carotid arteries.
- Saphenous vein patch angioplasty is a common technique to improve surgical outcomes.
- A rare but severe complication involves aseptic necrosis and rupture of the vein patch graft.
Observation:
- This complication typically occurs 2-7 days postoperatively without warning.
- Reoperation reveals necrotic central vein patch tissue, without signs of infection.
- All reported cases involve saphenous veins harvested from the ankle.
Findings:
- Small diameter saphenous veins appear to have a higher risk of rupture.
- Technical aspects of graft harvesting and preparation may contribute to the complication.
- The exact physical parameters predisposing veins to rupture require further investigation.
Implications:
- This complication can lead to devastating outcomes, including stroke and death.
- Surgeons should be aware of the risks associated with saphenous vein grafts, especially those from the ankle.
- Further research into graft preparation and vein selection may mitigate this risk.
