    (Turkish Neurosurgical Soc, 2023) Ciftci, Rukiye; Cetin, Aymelek; Ulubaba, Hilal Er; Senol, Deniz; Cinarli, Fahri Safa; Ozbag, Davut
    AIM: To examine the morphometric properties of the vessels forming the Willis polygon (WP) in patients with type 2 diabetes mellitus (T2DM) and hypertension (HT) and compare them with healthy individuals.MATERIAL and METHODS: Cranial Tomography Angiography (CTA) of 168 individuals were analyzed retrospectively. The individuals included in the study were divided into four groups according to the diagnosis. Group 1 included 40 individuals who were diagnosed with HT, Group 2 included 43 individuals who were diagnosed with DM, Group 3 included 42 individuals who were diagnosed with DM and HT, and Group 4 was the control group and included 43 individuals. The diameter and length measurements of the vesselsRESULTS: According to the results of the Kruskal Wallis H test, in female patients statistically significant differences were detected in the diameter measurements of the right and left A1 segment of the ACA, the diameter measurement of the left A2 segment, the diameter measurements of the right and left P1 and P2 segments of the ACP, the diameter measurements of the right and left AComP. (p<0.05), in male patients statistically significant differences were found in the diameter of the right A1 segment of the ACA, the diameter and segment length measurements of the right and left P1 segments of the ACP, of the right and left P2 diameter measurements, and segment length measurements of the left AComP (p<0.05).CONCLUSION: We also found that the vessel diameters were similar in the HT, DM and HT+DM groups, and smaller than the control group. In addition, we think that knowing WP morphometric measurements will both guide the radio-anatomical evaluations to be made and increase the level of microanatomical knowledge in surgical treatment.

    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
    (Turkish Neurosurgical Soc, 2022) Çiftçi, Rukiye; Ulubaba, Hilal Er; Şenol, Deniz; Toy, Şeyma; Yıldırım, İsmail Okan
    AIM: To examine the relationship between the morphologic features of the internal carotid artery (ICA) and symptoms affecting cerebral blood circulation including type 2 diabetes mellitus (T2DM) and hypertension (HT).MATERIAL and METHODS: In this study, retrospective morphometric analysis of ICA measurements from 100 patients (aged 45-60 years) was performed using 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 a healthy control group (group 4). Length and diameter measurements of the cervical, petrous, cavernous, and terminal segments of the ICA were made using 3D CTA images and recorded. The measurements of the male and female patients were compared using the Mann-Whitney U test and the groups were compared using the Kruskal-Wallis H test.RESULTS: It was found that there were statistically significant differences between male and female patients in terms of the 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 Kruskal-Wallis H test analysis results, it was determined that there were no statistically significant differences between the patients in the four groups for all segment measurements (p>0.05).CONCLUSION: It was determined that ICA was more affected by HT than diabetes. In addition, we think that being knowledgeable of morphometric measurements of ICA will guide radio-anatomic evaluations and increase the level of microanatomic knowledge in surgical treatment.

    Morphometry of the Middle Cerebral Arteries: A Radio-Anatomical Study Based on Computed Tomography Angiography Findings
    (Soc Chilena Anatomia, 2023) Ciftci, Rukiye; Toy, Seyma; Ulubaba, Hilal Er; Senol, Deniz; Cinarli, FS.; Sigirci, Ahmet
    Middle cerebral artery (MCA), which has the largest irrigation area of the arteries that feed the brain, is an important artery whose microanatomy should be well known because of its vascular variation. In pathologies which are known to affect the cerebrovascular system such as type 2 diabetes mellitus (T2DM) and hypertension, morphometric characteristics of MCA gain importance. The aim of this study is to compare the morphometric characteristics of M1 segment of MCA in T2DM and hypertensive patients with those of healthy control group by using computed tomographic angiography (CTA). The study was carried out with retrospective morphometric analysis of CTA images of 200 individuals between 40 and 65 years of age. The individuals were grouped in four as hypertensive patients (group 1), patients with T2DM (group 2), patients with hypertension and T2DM (group 3) and healthy control group (group 4). Length and diameter measurements of M1 segment were performed and recorded by using 3D CTA images. While statistically significant difference was found between bilateral M1 segment diameters of both women and men (p<0.05), no statistically significant difference was found between segment lengths (p>0.05). As a result of the post hoc analysis performed, it was concluded that right and left M1 segment diameter of group 1, group 2 and group 3 was found to be different from group 4 in both sexes (p<0.05). We believe that this study will both be a guide in radio-anatomic assessments to be performed and also increase microanatomic level of information in the surgical treatment of the artery by showing the morphometric changes that occur in M1 segment of MCA in T2DM diseases.
