THE STRUCTURE OF THE POSTOPERATIVE CEREBRAL DYSFUNCTION AFTER THE HEART VALVE SURGERY

In the structure of heart valve defects, the aortic valve is most often susceptible to pathological changes - 64.5%. Conservative treatment of valvular heart disease is mainly aimed at reducing the severity of heart failure, at a certain stage the implementation of a surgical operation becomes a vital manipulation. The aim of the study was to evaluate the frequency and determine the structure of postoperative cerebral dysfunction during surgical correction of acquired aortic valve defects, as well as to compare it with other cardiac surgery for heart valve defects in cardiopulmonary bypass. We examined 134 patients (86 men and 48 women, average age 64 years), who underwent planned operations for prosthetics of heart valves in conditions of cardiopulmonary bypass. Postoperative cerebral dysfunction was diagnosed in 41% (55 of 134 patients). The incidence of postoperative cerebral dysfunction during prosthetic surgery for aortic stenosis is 49% with the following structure: perioperative stroke 4.3%, symptomatic delirium of the early postoperative period 25.5% and 29.8% delayed cognitive impairment. In patients with other operations on the heart valves, postoperative cerebral dysfunction was diagnosed in 36.8%: perioperative stroke 1.15%, symptomatic delirium of the early postoperative period, delayed cognitive impairment 23.2%. There were no significant differences in the incidence of perioperative stroke and delayed cognitive impairment (p>0.05). Acute clinical types of postoperative cerebral dysfunction and symptomatic delirium early postoperative period were significantly more often (p<0.05) detected after prosthetics for aortic stenosis.
