Insights

A rare infant mycotic aneurysm of the ascending aorta caused by group A streptococcus was successfully repaired with an autologous pericardial patch. The child recovered well, showing normal development and heart rhythm at five years.

Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Infectious Diseases

Background:

  • Mycotic aneurysms of the ascending aorta are exceptionally rare in infants.
  • Group A Streptococcus septicemia can lead to severe complications, including aortic aneurysms.

Observation:

  • A 12-month-old infant presented with a mycotic aneurysm of the ascending aorta secondary to group A Streptococcus septicemia.
  • The infant developed atrioventricular block, and the aneurysm rapidly progressed despite medical management.

Findings:

  • Emergency surgical intervention was necessary due to rapid aneurysm progression and associated atrioventricular block.
  • The mycotic aneurysm was successfully repaired using an autologous pericardial patch.

Implications:

  • This case highlights the successful surgical management of a rare pediatric mycotic aortic aneurysm.
  • Autologous pericardial patch repair offers a viable option for complex aortic reconstructions in infants.
  • Early surgical intervention can lead to favorable long-term outcomes in infants with mycotic aortic aneurysms.

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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
