Abstract:
We report a rare case of pneumococcal aortitis secondary to endovascular bare-metal stent infection. The patient was a 70-year-old man presenting with back pain 1 year after aortoiliac implantation of bare-metal kissing stents. Final diagnosis was microbial aortitis due to Streptococcus pneumoniae involving the stents that resulted in a contained aortic rupture requiring urgent surgical treatment. Emergency extra-anatomic revascularization, excision of the infected tissues, and appropriate antibiotic therapy led to a favorable outcome. A high index of suspicion is required in such a situation because the mortality rate is very high in the absence of appropriate treatment.
Insights
A rare case of pneumococcal aortitis caused by infected stents led to aortic rupture. Prompt surgical intervention and antibiotics achieved a favorable outcome, highlighting the need for high suspicion in similar cases.
Area of Science:
- Cardiovascular Medicine
- Infectious Diseases
- Surgical Innovation
Background:
- Endovascular stent implantation is a common procedure for aortoiliac disease.
- Infection of bare-metal stents is a rare but serious complication.
- Microbial aortitis poses a significant threat to patient survival.
Observation:
- A 70-year-old male presented with back pain one year post-aortoiliac kissing stent implantation.
- Diagnosis revealed pneumococcal aortitis secondary to Streptococcus pneumoniae infection of the stents.
- The infection resulted in a contained aortic rupture.
Findings:
- Urgent surgical treatment was required, including extra-anatomic revascularization and infected tissue excision.
- Appropriate antibiotic therapy was crucial for managing the infection.
- The patient experienced a favorable outcome following the comprehensive treatment approach.
Implications:
- This case underscores the importance of considering stent infection in patients with delayed symptoms after endovascular procedures.
- A high index of suspicion is critical for early diagnosis and management of microbial aortitis.
- Prompt and aggressive treatment is essential to reduce the high mortality associated with this condition.
