Vrijednost nalaza kalcifikacija u projekciji karotidnih arterija na ortopantomogramu u otkrivanju stenoze karotidnih arterija – pregled istraživanja i preliminarni rezultat

Introduction: Stroke is the second most common cause of death and the leading cause of disability in adults worldwide. The most frequent cause of stroke are atherosclerotic changes of extracranial arteries, especially of carotids. The most susceptible location for atherosclerotic plaques in carotid arteries is shown on most orthopantomographs, and can be visualized if calcified. The aim of this study is to determine the correlation between calcifications in the projection of carotid arteries on orthopantomographs and carotid stenosis on Doppler ultrasound and MR angiography, and to analyze the relationship between stroke risk factors, calcifications in the projection of carotid arteries on orthopantomographs and degree of carotid stenosis. Materials and methods: To investigate the degree of carotid stenosis and the preexisting cerebrovascular disease, brain MRI, carotid Doppler ultrasound and MR angiography will be performed on one hundred patients with calcifications in the projection of carotid arteries on orthopantomograms. Only the orthopantomographs performed for dental indications will be used. Anamnestic data on stroke risk factors will also be gathered. Results: Preliminary data from 20% of patients has been gathered so far. All examined subjects had atherosclerotic changes of carotids, and over 65% showed signs of brain small vessel disease (cerebrovascular disease). Three patients have already had a stroke. At least one-sided incipient carotid stenosis was seen in most subjects (over 60% have ≥20% stenosis), but significant stenosis (>50%) has been found only in a small number of patients (7%). Conclusion: Preliminary results show a correlation between calcifications on orthopantomographs and significant carotid stenosis in a few subjects.
