Abstract. Objective. To improve the results of surgical treatment of patients with carotide body tumor through the study of the features of lesions of the major vessels of the neck. Materials and methods The analysis of the clinical symptoms of 72 patients who were hospitalized in the department of vascular surgery Lviv regional hospital for the period 1997 to 2017 in this group of patients in the 42 case diagnosed the carotid body tumor (study group) and 30 cases of tumors other oncogenesis in section of carotid arteries (control group). The calculation of statistical indicators performed using Excel 2010 with the definition of reliability of the results based on Fisher test. Results and discussion. Based on the data of ultrasound examination, computer tomography and the results of surgical intervention in patients with carotid body tumors, we observed thrombosis of jugular vein – 4.76% (p=0.1931), invasion in the vascular wall – 21.43% (p=0, 5344), the deviation of the internal carotid artery is 30.95% (p=0.0173, OR 6.86, 95%, 1.3-30.4), compression – 90.48% (p=0,0552). At the same time, the degree of stenosis of carotid arteries did not exceed 60%. In patients of the control group thrombosis of jugular vein was found in 13.33%, invasion in the wall of carotid arteries in 23.33%, deviation of the internal carotid artery in 10.0%, compression with the development of stenosis in 73.33%. Statistical analysis between groups showed a significant difference, that for carotid body tumor typical is compression on the vascular wall with the development of deviation of the internal carotid artery. The results of the study show that in case of carotide body tumor in one third of cases there is a deviation of the internal carotid artery. Therefore, in such patients, surgical interventions require the technique of correction of residual deformations of the internal carotid artery, which causes the resection and redistribution of the common carotid artery
