Abstract:
Vascular infections after percutaneous endovascular procedures are rare. We report a case of bacterial arteritis following PTA and stent implantation into an iliac artery. It was complicated by septic embolization, ipsilateral empyema of the knee joint and formation of an infected false aneurysm. Contamination of the stent with Staphylococcus aureus is likely to be the cause. The treatment included resection of the infected arterial segment, removal of the stent, and autologous reconstruction.
Insights
Bacterial arteritis is a rare complication following iliac artery stent implantation. Staphylococcus aureus contamination of the stent likely caused this infection, leading to serious complications requiring surgical intervention.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Interventional Cardiology
Background:
- Percutaneous endovascular procedures, including angioplasty with stent implantation, are common treatments for iliac artery disease.
- While generally safe, these procedures carry a risk of rare but serious complications, such as vascular infections.
Observation:
- A case of bacterial arteritis is presented following percutaneous transluminal angioplasty (PTA) and stent implantation in the iliac artery.
- The infection was complicated by septic embolization, leading to ipsilateral knee joint empyema and the formation of an infected false aneurysm.
Findings:
- Staphylococcus aureus contamination of the implanted stent is the presumed etiology of the bacterial arteritis.
- The clinical presentation included severe local and systemic signs of infection.
Implications:
- This case highlights the importance of recognizing and managing rare vascular infections post-endovascular procedures.
- Successful treatment involved aggressive surgical management, including resection of the infected arterial segment, stent removal, and autologous arterial reconstruction.
