Insights
A patient with coronary artery disease developed an epidural abscess, leading to leg weakness. Prompt surgical decompression and antibiotics resulted in significant neurological recovery.
Area of Science:
- Neurology
- Cardiology
- Infectious Disease
Background:
- A 53-year-old male with multiple comorbidities including diabetes, coronary artery disease, and hypertension presented with recurrent chest pain.
- The patient had recently undergone drug-eluting stent placement for right coronary artery stenosis.
- Non-compliance with antiplatelet medication (clopidogrel) raised concerns for in-stent thrombosis, though workup was negative.
Observation:
- The patient developed acute bilateral flaccid leg weakness, urinary retention, and sensory loss from the umbilicus downwards.
- Magnetic Resonance Imaging (MRI) revealed a T4-T6 epidural abscess.
Findings:
- Emergent decompression laminectomy and abscess drainage were performed.
- Post-operatively, the patient experienced rapid improvement in neurological deficits, with complete sensory recovery.
- Cultures identified Streptococcus sp., and the patient was treated with intravenous nafcillin for 8 weeks.
Implications:
- This case underscores the potential for serious neurological complications arising from spinal epidural abscesses.
- Prompt surgical decompression and appropriate antibiotic therapy are crucial for favorable neurological outcomes.
- Management requires a multidisciplinary approach, integrating neurosurgery, infectious disease, and rehabilitation.
Abstract:
A 53-year-old man with a history of diabetic foot ulcer, osteomyelitis, coronary artery disease, hypertension and hyperlipidaemia, presented with chest pain of 3 weeks duration. Eleven days earlier, the patient had had a drug-eluting stent (DES) placed in a branch of the right coronary artery (RCA) after similar chest pain, leading to the findings of a positive nuclear stress test. Since discharge, he was not compliant with taking clopidegrel (Plavix), a concern for in-stent thrombosis with recurrent myocardial ischaemia; but work up was negative and medications were restarted. Within 24 h of admission, he developed bilateral flaccid leg weakness, urine retention and loss of sensation from the umbilicus level down. MRI revealed a T4-T6 epidural abscess. Emergent decompression laminectomy and abscess drainage was completed. Neurological symptoms improved hours after surgery with complete resolution of sensory deficits. Cultures grew Streptococcus sp., treated with intravenous nafcillin for 8 weeks. He regained leg strength with continued improvement seen in rehabilitation.
