Abstract:
Primary pneumococcal aortic mycotic aneurysms are rare clinical entities. Only a few cases have been reported in the literature. Extremely rare presentation is the occurrence of three simultaneous aneurysms. Treatment usually necessitates intravenous antibiotherapy combined with staged surgical interventions. This report highlights the case of a 52-year-old man with multiple Streptococcus pneumoniae mycotic aneurysms that were simultaneously and successfully treated during a one-stage surgical procedure. The aorta may be prone to infection, especially when its intima is structurally altered by pathologic processes like atherosclerosis, inflammation or trauma. Mycotic aneurysm is a rare but serious vascular condition needing urgent medical and surgical attention because of potential lethal complications.
Insights
Multiple Streptococcus pneumoniae aortic mycotic aneurysms were successfully treated in a single surgery. This rare condition requires prompt medical and surgical intervention due to potential life-threatening complications.
Area of Science:
- Cardiovascular Surgery
- Infectious Diseases
- Vascular Surgery
Background:
- Primary pneumococcal aortic mycotic aneurysms are exceptionally rare vascular conditions.
- Atherosclerosis, inflammation, or trauma can predispose the aorta to infection.
- Mycotic aneurysms pose a significant risk of lethal complications if not urgently addressed.
Observation:
- A 52-year-old male presented with multiple, simultaneous aortic mycotic aneurysms.
- The patient was diagnosed with Streptococcus pneumoniae infection causing the aneurysms.
Findings:
- Successful simultaneous surgical treatment of multiple aortic mycotic aneurysms was achieved in a one-stage procedure.
- Intravenous antibiotherapy was administered in conjunction with surgical intervention.
Implications:
- This case demonstrates the feasibility of a one-stage surgical approach for multiple simultaneous mycotic aneurysms.
- Prompt diagnosis and combined medical-surgical management are crucial for favorable outcomes in mycotic aneurysm cases.
- Further research into optimal treatment strategies for complex mycotic aneurysms is warranted.
