English abstract
Objective: To determine sensitivity and specificity of multidetector-row computed tomography in detecting atherosclerotic carotid plaques complicated with intraplaque hemorrhage. ----- Material: Carotid plaques from 31 patients operated for carotid artery stenosis. ----- Methods: Results of preoperative multidetector-row computed tomography analysis of carotid plaques were compared with results of histological analysis of the same plaque areas. Carotid endarterectomy was performed within one week of multidetector-row computed tomography. American Heart Association classification of atherosclerotic plaques was applied for histological classification. ----- Results: Median tissue density of carotid plaques complicated with intraplaque hemorrhage was 22 Hounsfield units. Median tissue density of noncalcified segments of uncomplicated plaques was 59 Hounsfield units (p=0.0062). The highest tissue density observed for complicated plaques was 31 Hounsfield units. Multidetector-row computed tomography detected plaques complicated with hemorrhage with sensitivity of 100% and specificity of 64.7%, with tissue density of 31 Hounsfield units as a threshold value. ----- Conclusion: Multidetector-row computed tomography showed high level of sensitivity and moderate level of specificity in detecting atherosclerotic carotid plaques complicated with hemorrhage.
