Abstract

Insights

This case report details the first successful endovascular repair of an intracranial mycotic aneurysm in a patient with a left ventricular assist device (LVAD). Prompt diagnosis and intervention are crucial for managing this rare complication.

Area of Science:

  • Cardiovascular Surgery
  • Neurology
  • Infectious Diseases

Background:

  • Mycotic aneurysms are a known complication of infective endocarditis.
  • Infection of left ventricular assist devices (LVADs) can lead to bacteremia and complications similar to prosthetic valve endocarditis.
  • Intracranial mycotic aneurysms are rare, often presenting with subarachnoid hemorrhage in patients with bacteremia.

Purpose of the Study:

  • To report the first case of an intracranial mycotic aneurysm secondary to LVAD infection.
  • To highlight the successful treatment of this rare condition using endovascular intervention.

Main Methods:

  • Case presentation of a patient with an LVAD experiencing headache.
  • Diagnosis confirmed via computed tomography angiography of the head.
  • Successful treatment with endovascular intervention.

Main Results:

  • An intracranial mycotic aneurysm was identified in a patient with an LVAD.
  • The patient underwent successful endovascular repair.
  • This represents the first reported case of its kind.

Conclusions:

  • Intracranial mycotic aneurysms are a rare but serious complication in LVAD patients.
  • A high index of suspicion is necessary for diagnosing mycotic aneurysms in patients with bacteremia and neurological symptoms.
  • Endovascular repair is a viable treatment option for these rare aneurysms.

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...

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...

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...
