Summary
Severe restenosis after coronary stent implantation can occur due to pre-dilation hematoma, even when dissection is sealed. This case highlights the importance of considering vasa vasorum injury in patients on long-term steroids.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Medical Complications
Background:
- Dissection is a known complication of percutaneous coronary intervention (PCI).
- Coronary artery dissection covered by a stent is generally considered safe.
- Severe restenosis can arise from pre-dilation hematoma extending post-stent implantation.
