Evaluation of infarct types and related cerebral vessels in the presence of different risk factors by three-dimensional (3D) imaging methods in patients with ischemia

Purpose: The factors that predispose to stroke are defined as risk factors. The subtypes of stroke can be classified by considering the changeable risk factor and its relationship with stroke. The aim of this study is to examine the infarction types and related brain vessels in the presence of different risk factors in ischemia patients by rendering three-dimensional (3D) cross-sectional ischemic damaged brain regions on magnetic resonance (MR) and computed tomography (CT) images obtained from patients. Material and methods: 105 patients (53 male, 52 female) with ischemia and 50 normal (23 male, 27 female) members of control group were participated in the study. A number of cross-sectional images (transverse, sagittal and coronal sectiones) were reconstructed on computer. Infarct types were classified as atherosclerotic, cardioembolic, lacunar, cryptogenic and transient ischemic attacks. The infarct size was determined in infarct types in patients with hypertension, diabetes, smoker and coronary artery disease. The arteries that irrigate the infarct area were classified. The most infarcted arteries and the largest infarcted arteries were evaluated statistically. Results: Infarct types were anatomically correlated with their infarct size and the arteries causing infarction. Thus, which arteries cause which types of infarcts in which risk factors are described firstly in the literature. Conclusion: The infarct size in the brain is of great clinical importance. It has been observed that clinical findings become more pronounced as infarct size increases. This situation varies according to the localization of ischemia. The risk factors and types of infarcts vary in men and women. These results are thought to be the basis for explaining the mechanisms of clinical findings.
