Summary
This case report details treating unstable angina in a patient with a radial artery graft. Sirolimus-eluting stents effectively managed in-stent restenosis after conventional stenting.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Surgery
Background:
- A 67-year-old female patient presented with unstable angina.
- She had a history of myocardial revascularization, including a left internal thoracic artery graft and a radial artery (RA) graft to the right coronary artery.
- Coronary angiography revealed a 90% stenosis in the RA graft.
Observation:
- The initial treatment involved conventional stenting of the stenosed RA graft.
- Two months post-procedure, the patient experienced recurrent unstable angina due to in-stent restenosis.
- This necessitated a repeat intervention.
Findings:
- In-stent restenosis in the radial artery graft was successfully treated with a sirolimus-eluting stent.
- Six-month follow-up showed the patient remained asymptomatic with a sustained positive outcome.
- The case highlights the challenges associated with percutaneous interventions in radial artery grafts.
Implications:
- Sirolimus-eluting stents can be effective in managing in-stent restenosis within radial artery grafts.
- This case underscores the need for careful consideration of graft type and potential complications in coronary artery bypass grafting.
- Further research into optimal interventional strategies for radial artery graft stenosis is warranted.
