Materials and methods: The analysis of the clinical symptoms of 56 patients who were hospitalized in the department of vascular surgery Lviv regional hospital for the period 1995 to 2015 in this group of patients in the 31 case diagnosed tumor of the carotid body (study group) and 25 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: In the group of carotid body tumor (CBT) main symptom is the appearance of painless, round, tight elastic consistency, formation of the neck in the projection of the bifurcation of the common carotid artery, which slowly increased in size in 25 (81 %) patients with CBT, episodes of vertigo in 9 (17 %) of clinical cases, headache - 7 (23 %), episodes of fainting - 5 (16 %), the appearance of a painful lesion on his neck - 6 (19%), lymphadenopathy - 5 (16 %), amnesia - 2 (6 %), dysphagia - 2 (6 %), dysarthria - 2 (6 %), cough, ear disorder - 1 (3 %). In 5 (16 %) patients with CBT, we diagnosed the syndrome of carotid sinus. Based on the comparative analysis between the frequency of symptoms in study groups CBT statistically significant is the emergence of asymptomatic tumor in the neck in the projection of carotid arteries in 81% of patients (p = 0.0021), dizziness in 29% of patients (p= 0.0489), syndrome of carotid sinus in 16% (p = 0.0445). Conclusions:Analysis of the clinical picture in patients with carotid body tumor shown that this disease is marked by the appearance of no pain, oval, tight elastic consistency tumor in the neck in the projection of the bifurcation of the common carotid artery, which is accompanied by dizziness and syndrome of carotid sinus.
