To determine the features of the cognitive sphere in patients who underwent thrombectomy for thrombotic occlusion in the late postoperative period.

Objective: To determine the characteristics of cognitive function in patients who have undergone thromboectomy for thrombotic occlusion during the long-term postoperative period.

During 2023—2024, a prospective study of 96 patients who underwent thrombectomy for thrombotic occlusion was conducted at the Center for Roentgen Endovascular Neurosurgery of the Kyiv City Clinical Hospital No. 1 (Kyiv, Ukraine). The study of early psychiatric consequences took place in the early postoperative period — on the 7—8th day after surgery using clinicalanamnestic, clinical-psychopathological and psychodiagnostic research methods. The severity of cognitive deficit was determined using the Trail Making Test (TMT, R. M. Reitan and D. Wolfson, 1993), the Stroop Color Word Interference Test (J. R. Stroop, 1935), and the Luria's Ten Unrelated Words Test (A. R. Luria, 1969)

The features of the cognitive sphere in patients who underwent thrombectomy of thrombotic occlusion in the late postoperative period were determined. Thus, 30—35 days after the surgical intervention, the cognitive profile of the selected contingent of patients was characterized by moderate impairments of functions that affect the speed of the associative process, determine their rigidity, which was combined with difficulties in switching attention and a tendency to exhaustion of mental processes, violations of the process of transferring information from the short-term to the long-term category.

The obtained data on the features of the cognitive sphere of patients in the acute postoperative period will allow forming the basis for a system of comprehensive rehabilitation of patients, which will correspond to the principles of personalized medicine.
