Abstract

Insights

Mycotic abdominal aortic aneurysms (AAAs) caused by Listeria monocytogenes are rare but serious. Surgical resection with long-term antibiotics is the recommended treatment for these infected AAAs.

Area of Science:

  • Vascular Surgery
  • Infectious Diseases
  • Microbiology

Background:

  • Infected abdominal aortic aneurysms (AAAs) present with varied symptoms, from subtle to overt rupture.
  • Listeria monocytogenes is a rare cause of arterial aneurysms.

Purpose of the Study:

  • To report two cases of mycotic AAA caused by Listeria monocytogenes.
  • To discuss the presentation, management, and risk factors associated with Listeria monocytogenes-induced AAAs.

Main Methods:

  • Case report of two patients with mycotic AAA due to Listeria monocytogenes.
  • Both patients underwent surgical excision of infected tissue and inlay prosthetic repair.
  • Long-term antibiotic therapy was administered to both patients.

Main Results:

  • One patient presented with a ruptured AAA, the other with a symptomatic non-ruptured AAA.
  • Computer tomography (CT) angiogram showed peri-aortic inflammation and rapid aneurysm expansion in the non-ruptured case.
  • Both patients were successfully treated with surgery and antibiotics.

Conclusions:

  • Listeria monocytogenes-induced abdominal aortic aneurysms require surgical resection and prolonged antimicrobial therapy.
  • Risk factors include immunosuppression, infective endocarditis, intravenous drug use, and sepsis.
  • Consultation with health protection agencies and microbiologists is advised for Listeria infections.

Aneurysm I: Introduction01:30

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 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: Introduction01:26

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,...

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...
Appendicitis01:19

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
Bacterial Meningitis I: Introduction01:22

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...
