Cushing’s syndrome is caused by adrenocorticotropic hormone (ACTH)-secreting or cortisol-secreting tumors. In most cases, the hypercortisolism is caused by an ACTH-secreting tumor of the pituitary. An excess of circulating cortisol adversely affects all major organ systems, including the cardiovascular system and therefore produces a wide range of clinical features. Perioperative morbidity and mortality will largely be determined by the magnitude of cardiac dysfunction encountered. Successful perioperative management depends on a thorough preoperative assessment of affected organs, comprehensive intraoperative monitoring, and an understanding of potential interactions with anesthetic drugs. Surgical reselection is most often the definitive treatment for this syndrome, however there are pharmacologic interventions that can be undertaken when necessary.
