Abstract

Insights

This case report details a rare instance of infectious aortitis caused by Prevotella intermedia. Prompt surgical intervention and a six-week antibiotic course led to a successful recovery from this life-threatening condition.

Area of Science:

  • Cardiovascular Surgery
  • Infectious Diseases
  • Vascular Surgery

Background:

  • Aortitis encompasses inflammation of the aortic wall, presenting diverse etiologies.
  • Infectious aortitis, though rare, poses significant life-threatening risks.
  • Prevotella intermedia is an uncommon pathogen implicated in infectious aortitis.

Purpose of the Study:

  • To report a case of infectious aortitis caused by Prevotella intermedia.
  • To describe the surgical and antibiotic management of this rare condition.
  • To highlight the importance of multidisciplinary care in managing acute aortitis.

Main Methods:

  • A 44-year-old male presented with symptoms suggestive of aortitis, including fever and abdominal/back pain.
  • Computed tomography angiography revealed aortic atherosclerosis, contained rupture, and signs of inflammation.
  • Surgical aortic reconstruction was performed, followed by a six-week course of antibiotics targeting Prevotella intermedia.

Main Results:

  • Blood cultures confirmed Prevotella intermedia as the causative agent.
  • The patient underwent successful aortic reconstruction and recovered uneventfully.
  • Postoperative antibiotic therapy was crucial for resolving the infection.

Conclusions:

  • Acute aortitis is a complex clinical challenge requiring prompt diagnosis and management.
  • Infectious aortitis necessitates aggressive antibiotic treatment (minimum six weeks) and close monitoring.
  • Management should occur in specialized centers with experienced multidisciplinary teams.

Endocarditis I: Introduction01:25

Endocarditis 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...

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Endocarditis III: Medical Management

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
