[Wound infection after carotid artery endarterectomy caused by methicillin-resistant Staphylococcus aureus: case

Abstract

Insights

A rare but serious complication of carotid endarterectomy is methicillin-resistant Staphylococcus aureus (MRSA) graft infection. Aggressive surgical replacement of the infected graft with an autologous vein conduit is crucial for successful treatment.

Area of Science:

  • Vascular Surgery
  • Infectious Diseases
  • Surgical Complications

Background:

  • Carotid endarterectomy effectively treats >70% internal carotid artery stenosis.
  • Methicillin-resistant Staphylococcus aureus (MRSA) poses a significant risk for post-endarterectomy wound infections, leading to high morbidity and mortality.

Observation:

  • A 62-year-old female patient developed a synthetic graft infection due to MRSA following carotid endarterectomy.
  • Initial antibiotic and local wound treatments over two years proved unsuccessful.

Findings:

  • Surgical replacement of the MRSA-infected synthetic graft with an autologous saphenous vein conduit was performed.
  • This aggressive surgical intervention led to a successful outcome.

Implications:

  • Early and aggressive surgical management, including graft replacement, is vital for managing rare but life-threatening MRSA graft infections after carotid endarterectomy.
  • Autologous saphenous vein conduits represent a viable option for reconstructing the carotid artery in cases of synthetic graft infection.

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...

Mechanism of Antibiotic Resistance in MRSA

Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and acquisition...

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...
