Computed angiography for planning carotid surgery

Abstract

Objective: to evaluate accuracy of computed angiography in preoperative assessment of carotid occlusive disease. Material and Method: During 2013-2016 years 256 patients underwent preoperative examinations, that included ultrasound (study of brachiocephalic arteries (BCA), transcranial Doppler and computed angiography (CTA). Received with computed angiography data were analyzed with criteria NASCET (North American Symptomatic Carotid Endarterectomy Trial) and ECST (European Carotid Surgery Trial). Results: Unilateral occlusive disease was observed in majority of patients, occlusive lesions in carotid arteries was usually accompanied with changes in other vascular territories. In 29 cases (11%) in patients with internal carotid subocclusion (ICA) a distal diff use narrowing of lumen was observed. Comorbid diseases that aff ect management of our patients were: intracranial aneurysms (4%), lesions of larynx and pharynx (1%), lung cancer (1%). Conclusion: Computed angiography is necessary for carotid surgery planning.
