Doppler sonography of the carotid arteries in patients treated by radiation after laryngectomy.
The authors examined by Doppler sonography 86 patients undergoing rehabilitation after being treated for malignant tumor of the larynx by radical surgery and radiotherapy. In 39.5% of the patients pathological results were registered mainly in the extracranial segment of the carotids. Focal neurological deficits were registered only in 3 patients, while all the others were asymptomatic. The correlation between the time elapsed after radiotherapy and the stenotic-occlusive changes registered in the carotids, as well as the effect of hypertension, diabetes and smoking were analysed. The results suggest the influence of ionizing radiation on the occurrence of stenotic-occlusive processes in the neck segment of the carotid arteries. The population of patients examined is considered at risk of stroke.
