Morphometric Examinations of Internal Carotid Arteries of Patients with Hypertension and Patients with Type 2 Diabetes Mellitus: A Radio Anatomic Study Based on Computed Tomography Angiography Findings.

Abstract

The aim of this study is to examine the relationship between the morphological features of A.carotis interna (ICA) and symptoms affecting cerebral blood circulation including type 2 diabetes mellitus (T2DM) and hypertension (HT). In this study, retrospective morphometric analysis of ICA measurements from 100 patients (45-60 years old) was performed on Computed Tomographic Angiography (CTA) images. The images were divided into four groups: patients with HT (group 1), patients with T2DM (group 2), patients with HT and T2DM (group 3), and healthy control group (group 4). Length and diameter measurements of the cervical, petrous, cavernous and terminal segments of the ICA were made by using 3D CTA images and recorded. The measurements of the male and female patients were compared by Mann Whitney-U test and the the groups were compared by using Kruskall Wallis H test. It was found that, there were statistically significant differences between male and female patients in terms of right and left petrous, cavernous and terminal segments of the ICA in Group 1, right and left cervical left cavernous in Group 3, left cervical, right and left petrous, cavernous and right cavernous in Group 4 (p 0.05). According to the Kruskall Wallis H test analysis results, it was determined that there was no statistically significant difference between the patients in 4 groups for all segment measurements (p 0.05). As a result; It was determined that ICA was more affected by hypertension than diabetes. In addition, we think that being knowledgeable of morphometric measurements of ICA will guide the radio-anatomical evaluations and increase the level of microanatomical knowledge in surgical treatment.
