Infected false femoral artery aneurysms secondary to monitoring catheters
Related Experiment Videos
Abstract:
Six patients who developed infected false femoral artery aneurysms secondary to monitoring catheters are reported. All aneurysms were infected and resulted in systemic sepsis. Initially the origin of the sepsis was not obvious. Findings which suggest this lesion include staphylococci. Appearance of distal petechial hemorrhages should lend a strong suspicion to the possibility of the lesion. Appearance of the pulsatile groin mass completes the diagnosis. Only aneurysmal resection combined with appropriate antimicrobial therapy is curative. For necessary revascularization procedures, autogenous vein grafts should be used when available.
Insights
Infected false femoral artery aneurysms from monitoring catheters can cause sepsis. Prompt diagnosis and surgical resection with antibiotics are crucial for patient recovery.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Medical Devices
Background:
- Femoral artery aneurysms can develop as a complication of indwelling monitoring catheters.
- These false aneurysms are prone to infection, leading to serious systemic complications.
Observation:
- Six cases of infected false femoral artery aneurysms secondary to monitoring catheters are presented.
- Patients presented with systemic sepsis where the source was not initially apparent.
- Key diagnostic indicators include Staphylococcus infection, distal petechial hemorrhages, and a pulsatile groin mass.
Findings:
- All reported aneurysms were infected, causing systemic sepsis.
- Staphylococcal infection was a common finding suggesting the lesion's origin.
- The presence of distal petechial hemorrhages and a pulsatile groin mass are strong diagnostic clues.
Implications:
- Early recognition of infected false aneurysms is critical for managing sepsis.
- Surgical resection of the aneurysm combined with antimicrobial therapy is the curative treatment.
- Autogenous vein grafts are recommended for revascularization when necessary.
