Insights
A diabetic patient with recurrent bacteremia after bypass surgery was treated percutaneously for a giant coronary artery pseudoaneurysm. This minimally invasive approach successfully closed the pseudoaneurysm, improving the patient's condition.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Medical Imaging
Background:
- A 53-year-old male with diabetes mellitus and sternal dehiscence experienced recurrent Staphylococcus bacteremia two years post-coronary artery bypass grafting (CABG).
- Imaging revealed a giant pseudoaneurysm of the right coronary artery (RCA) and a coronary cameral fistula.
Observation:
- The patient presented with a complex cardiac anomaly following CABG, complicated by recurrent bloodstream infections.
- High surgical risk precluded traditional open-heart repair for the RCA pseudoaneurysm and fistula.
Findings:
- Percutaneous closure of the giant RCA pseudoaneurysm and coronary cameral fistula was achieved using a 5mm Amplatzer vascular plug.
- Post-procedure imaging confirmed successful occlusion of the pseudoaneurysm, and follow-up CT scans showed significant reduction in its size.
Implications:
- Percutaneous embolization offers a viable, less invasive alternative for managing complex coronary artery pseudoaneurysms in high-risk patients.
- This case highlights the potential of interventional techniques to address post-surgical cardiac complications effectively.
- Successful treatment may reduce the risk of recurrent bacteremia and improve long-term outcomes in selected patients.
Abstract:
A 53-year-old diabetic male with sternal dehiscence presented with recurrent staphylococcus bacteremia 2years after coronary artery bypass grafting (CABG). He was found to have a giant right coronary artery (RCA) pseudoaneurysm and a coronary cameral fistula on imaging. Due to excessive surgical risk, the patient underwent percutaneous treatment with a 5mm Amplatzer vascular plug 4 (St. Jude Medical, St.Paul, MN). Post-procedure imaging showed successful cessation of flow into the pseudoaneurysm and follow-up CT scan demonstrated significant improvement in the size of the pseudoaneurysm.
