Anaesthetic management for drainage of frontoparietal abscess in a patient of uncorrected Tetralogy of Fallot.

Abstract

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease, characterised by aortic overriding, right ventricular hypertrophy, pulmonary stenosis (PS) and ventricular septal defect (VSD). When left untreated, survival to adulthood is rare.[1] Brain abscesses can occur in them because of paradoxical embolism and absence of pulmonary phagocytic clearance of pathogens. There are few case reports of uncorrected TOF surviving to adulthood and then presenting for non-cardiac surgeries.[1,2,3] We present a case of drainage of a large left fronto-parietal abscess under general anaesthesia, in a patient of uncorrected TOF.
