Insights
Percutaneous coronary intervention (PCI) can cause rare but serious coronary artery perforation. A hybrid surgery combining coil embolization and coronary artery bypass grafting (CABG) successfully treated a patient with this complication.
Area of Science:
- Interventional Cardiology
- Cardiovascular Surgery
Background:
- Percutaneous coronary intervention (PCI) is a common treatment for coronary artery disease.
- Coronary perforation is a rare but serious complication of PCI, potentially leading to cardiac tamponade and increased mortality.
- Managing coronary perforation can be challenging, especially when standard treatments fail.
Purpose of the Study:
- To report a case of coronary perforation following drug-eluting stent (DES) deployment during PCI.
- To evaluate the efficacy of a hybrid surgical approach for managing refractory coronary perforation.
- To present a novel treatment strategy for a life-threatening PCI complication.
Main Methods:
- A case study of an 88-year-old male patient with right coronary artery occlusion.
- Coronary perforation occurred after DES implantation, with persistent bleeding despite covered stent use.
- Hybrid surgery involving coronary artery bypass grafting (CABG) and coil embolization was performed.
Main Results:
- The patient experienced coronary perforation after DES implantation.
- Covered stent implantation failed to control the bleeding.
- Hybrid surgery with CABG and coil embolization was successfully performed.
- The patient recovered uneventfully and was discharged on postoperative day 59.
Conclusions:
- Coronary perforation is a significant complication of PCI.
- Standard treatments may be insufficient for severe coronary perforations.
- A combination of coil embolization and CABG offers a potential alternative strategy for managing complex coronary perforations.
Abstract:
In recent years, percutaneous coronary intervention( PCI) has become mainstream for the treatment of coronary artery disease, and complications associated with this procedure are increasing accordingly. Coronary perforation, a complication of PCI, is rare but may lead to cardiac tamponade. Once cardiac tamponade occurs, the mortality rate increases. An 88-year-old man underwent coronary angiography that showed perfect right coronary occlusion. Coronary perforation occurred after the deployment of a drug-eluting stent( DES). We could not stop the bleeding despite covered stent implantation. We performed hybrid surgery, coronary artery bypass grafting (CABG) and coil embolization. The patient progressed uneventfully and was discharged on postoperative day 59. The combination of coil embolization and CABG may be an alternative strategy for treating coronary perforation.
