Insights

Pediatric deep neck infections can rarely cause internal carotid artery pseudoaneurysms. Early recognition and conservative management, as seen in this infant case, can lead to good long-term outcomes despite artery stenosis.

Area of Science:

  • Vascular Surgery
  • Pediatric Infectious Diseases
  • Neuroradiology

Background:

  • Pseudoaneurysms of the internal carotid artery (ICA) are rare complications of deep neck space infections in children.
  • Prompt diagnosis and management are crucial to prevent severe patient outcomes.

Observation:

  • This case report details an infant who developed a left ICA pseudoaneurysm following a retropharyngeal abscess.
  • The abscess was surgically drained, and the pseudoaneurysm was treated conservatively with antibiotics.

Findings:

  • The patient experienced 50% stenosis of the left ICA post-treatment.
  • A 7-year follow-up revealed no neurological deficits or developmental issues.
  • Cerebral blood flow to the left hemisphere remained adequate via the circle of Willis.

Implications:

  • This case underscores the importance of early detection and aggressive management of ICA pseudoaneurysms in pediatric deep neck infections.
  • Conservative management may be a viable option for selected cases.
  • Long-term surveillance is essential to monitor for potential complications like stenosis.

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
Staphylococcal Skin Infections01:29

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...
