Treatment of Brain Abscess in Patient with Eisenmenger Syndrome

Eisenmenger syndrome (ES) is a complex multisystem disorder caused by untreated congenital heart disease. Management of brain abscess in ES is challenging, as treatment decisions must balance infection control with altered cardiopulmonary physiology, necessitating a multidisciplinary approach. We present a case of a 45-year-old male with ES and symptomatic brain abscess treated successfully with abscess aspiration under monitored anesthesia care (MAC) and appropriate antibiotic therapy. We share our experience, outline key perioperative considerations, and discuss relevant literature.
