Brain abscess associated with congenital heart disease

Area of Science:

• Neurosurgery
• Cardiology
• Infectious Diseases

Background:

• Brain abscess is a serious complication in patients with congenital heart disease (CHD).
• Tetralogy of Fallot was the most frequent type of CHD observed in affected individuals.
• The study encompasses a significant case series spanning over three decades.

Purpose of the Study:

• To analyze the clinical characteristics and treatment outcomes of brain abscess in patients with CHD.
• To discuss the underlying etiology of brain abscess in this specific patient population.
• To evaluate the effectiveness of surgical interventions for brain abscess in CHD patients.

Main Methods:

• Retrospective review of 25 cases of brain abscess with CHD treated between 1952 and 1985.
• Analysis of patient demographics, CHD type, abscess location, microbiological findings, and treatment modalities.
• Assessment of mortality rates associated with the condition and its management.

Main Results:

• The majority of patients (13/25) had tetralogy of Fallot.
• Abscesses were commonly located in the parietal, frontal, and temporal lobes.
• Pus was sterile in most cases (13/19); Streptococcus was the predominant pathogen when identified.
• Surgical aspiration via burr hole was the primary treatment, with a 32% overall mortality rate.

Conclusions:

• Brain abscess presents a significant challenge in patients with congenital heart disease.
• Prompt surgical intervention, primarily aspiration, is crucial for managing brain abscesses in this cohort.
• Understanding the etiology and optimizing treatment strategies are essential to improve outcomes and reduce mortality.
