Intima-Media-Thickness (IMT) bei Patienten mit vertebrobasilären und karotidalen Stenosen/Verschlüssen
type: CreativeWork
description: Introduction: The Intima-Media-Thickness (IMT) of the commom carotid artery (CCA) is often used as a parameter for generalized atherosclerotic lesions of the vessel wall. It is possible to visualize the increase of the IMT in an early degree of athrosclerosis as a double line pattern in the sonographical picture (B-mode). The demographic difference of the IMT (e.g. between men an women) and the effect of the classical cerebrovascular risk factors on the IMT are sufficiently known. The difference of the side (right and left carotid artery) and the localisation in the carortid arteries of the IMT are already illuminated. It is not known actually, if different types of atherosclerosis are accompanied by a different IMT. The purpose of the study was to invesigate the IMT in patients with stenoses or occlusions in the vertebrobasilar system (VBS) and the carotid system (CS). Patients and methods: The Intima-Media-Thickness (IMT) and the diameter (QD) of the common carotid artery (CCA) (as a parameter of proliferative and dilatative form of atherosclerosis) were measured on both sides on areas of vessel wall without stenoses and plaques. We examined of the neck 121 people, including 32 normal healthy counds, 57 patients with stenoses or occlusions in the CS and 16 patients with macroangiopathy exclusively in the VBS. Patients of the fourth group (n=16) suffered from both VBS- and CS-macroangiopathy (CS/VBS) (following doppler- and duplex sonographical criteria). The classical cerebrovascular risk factors (age, arterial blood pressure, hypercholesterolemia, diabetes mellitus, family history, smoking status) were entered in a questionnaire. Results: In control persons, a IMT of 0,67±0,2 mm and a CCA-diameter of 5,8±1,2 mm was found. Patients with CS-macroangiopathy exhibited a significant higher IMT with 0,97±0,2 mm (p<0,0001) and a larger CCA-diameter (6,6±1,2 mm, p<0,01). In comparison to the controls we also found a significant higher IMT (0,86±0,2 mm, p<0,001) and a lar…
