Abstract Introduction Between 20–50% of neurosurgical patients may develop early periop- erative complications, and 25% have more than one clinical complication. The most commons are high blood pressure (25%) and cardiovascular events (7%). Intraoperative hypertension is characterized by an increase of 20% in basal blood pressure. Objectives The aim of this paper is to review and discuss the pathophysiology, diagnosis and treatment of perioperative hypertension in patients undergoing neuro- surgery, and to propose one table with therapeutic options. Methods A review using Scielo, PubMed, Ebsco and Artmed databases with inclusion and exclusion criteria. Articles published from 1957 to 2015 were selected. Discussion Five factors were established as causes: arterial hypertension, clinical conditions, surgical procedures, and operative and anesthetic factors. Specificcauses Keywords preoperative, intraoperative and posoperative. The pathophysiology may have some ► postoperative period relationship with catecholamines and sympathetic nervous system stimulation. ► arterial hypertension Conclusion Perioperative hypertension in neurosurgery may have many causes, ► neurosurgery some of them recognizable and preventable.
