Summary
Infected aortic endografts are rare but serious. This case highlights a unique aortic graft infection caused by Propionibacterium acnes, a skin bacterium, following embolization for a type II endoleak.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Bacteriology
Background:
- Infected aortic endografts present significant patient morbidity and mortality.
- Type II endoleaks can lead to aortic sac expansion, necessitating intervention.
Observation:
- A case of infected aortic endograft following percutaneous translumbar sac embolization for type II endoleak is presented.
- The patient developed sac expansion attributed to the endograft infection.
Findings:
- The causative pathogen identified was Propionibacterium acnes, a common skin bacterium.
- This represents the first reported instance of aortic graft infection specifically by P. acnes.
Implications:
- Highlights a novel etiology for aortic endograft infections.
- Suggests the need for vigilance regarding unusual pathogens in graft infections.
- Underscores the importance of timely graft explantation and reconstruction for managing such infections.

01:25Endocarditis 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...
01:26Aneurysm 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...
01:29Staphylococcal 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...
01:26Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...
