Fatal soft-tissue infection complicating pulmonary arteriovenous fistulae
The American Journal of the Medical Sciences
|May 1, 1987
Abstract:
A patient with pulmonary arteriovenous (AV) fistulae presented with an ultimately fatal anaerobic soft tissue infection. This represents the first report of such a complication, but the association of intracerebral anaerobic abscess with pulmonary AV fistulae suggests the possibility of a common pathophysiologic mechanism.
Insights
Pulmonary arteriovenous fistulae can lead to severe anaerobic soft tissue infections, a rare but fatal complication. This case highlights a potential link between these fistulae and anaerobic brain abscesses, suggesting a shared underlying cause.
Area of Science:
- Medical Science
- Infectious Diseases
- Vascular Biology
Background:
- Pulmonary arteriovenous (AV) fistulae are abnormal connections between pulmonary arteries and veins.
- These vascular malformations can lead to various complications, including paradoxical embolism and hemorrhage.
- Anaerobic infections are typically associated with specific risk factors and anatomical locations.
Observation:
- A patient with known pulmonary AV fistulae developed a severe, ultimately fatal, anaerobic soft tissue infection.
- This represents the first documented instance of such a soft tissue infection in the context of pulmonary AV fistulae.
- Previous literature has noted an association between pulmonary AV fistulae and intracerebral anaerobic abscesses.
Findings:
- The occurrence of a fatal anaerobic soft tissue infection in a patient with pulmonary AV fistulae is a novel observation.
- The findings suggest a potential, previously unrecognized, complication of pulmonary AV fistulae.
- The association with previously reported cases of anaerobic brain abscesses points towards a possible common pathophysiologic mechanism.
Implications:
- This case underscores the importance of considering anaerobic soft tissue infections in patients with pulmonary AV fistulae.
- It prompts further investigation into the pathophysiologic mechanisms linking pulmonary AV fistulae to anaerobic infections, particularly in the brain and soft tissues.
- Enhanced vigilance and diagnostic approaches may be warranted for patients with pulmonary AV fistulae presenting with signs of infection.

01:30Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

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...
01:29Endocarditis 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...
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...
01:25Hemodialysis I: Introduction
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
01:29Pneumonia I: Introduction
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
