A Case of Transposition of Great Arteries with Ventricular Septal Defect and Mesocardia Presenting for Neurosurgery.

Congenitally corrected transposition of great arteries (CC-TGAs) associated with a ventricular septal defect (VSD) presents with cyanotic spells and systemic complications such as brain abscess. In mesocardia, the heart lies in the midline with no apex seen on the left side. We report the anesthetic management of a child with CC-TGA, VSD, and mesocardia presenting with parietal brain abscess for neurosurgery. The significant anesthetic challenges include maintenance of peripheral vascular resistance lower than systemic vascular resistance, prevention of air embolism and paradoxical embolism, avoidance of hyperviscosity in addition to avoiding any rise in intracranial pressure, and maintenance of cerebral perfusion pressure.
