An expanding forearm phlegmon and subsequent compartment syndrome

Area of Science:

• Infectious Diseases
• Vascular Surgery
• Emergency Medicine

Background:

• Forearm phlegmon and compartment syndrome are serious conditions requiring prompt diagnosis and management.
• Endocarditis, an infection of the heart lining, can lead to embolic events and systemic complications.
• Dental procedures, while common, carry a risk of transient bacteremia, potentially seeding distant infections.

Observation:

• A young, physically fit female presented with a rapidly progressing forearm phlegmon.
• The phlegmon led to the development of acute compartment syndrome, necessitating urgent surgical intervention.
• Systemic investigations revealed underlying infective endocarditis as the likely source of the infection.

Findings:

• The patient's endocarditis was confirmed via blood cultures and echocardiography.
• A direct link between recent dental work and the onset of endocarditis was established.
• Successful management involved a combination of antibiotics, surgical decompression, and addressing the cardiac source.

Implications:

• This case underscores the importance of considering endocarditis in young, healthy individuals presenting with seemingly localized infections.
• It highlights the potential for dental procedures to trigger severe systemic complications like endocarditis and secondary phlegmon formation.
• Clinicians should maintain a high index of suspicion for endocarditis in patients with unexplained infections, particularly following invasive procedures.
