Carotid Web Incidence and Radiological Classification, Determination of Its Relationship With Ischemic Stroke

Study Overview
=================
Brief Summary
-----------------
In our research, we aim to increase awareness on this issue by classifying the frequency of carotid webs and their radiological classification; Evaluating the clinical data and vascular risk factors of carotid web cases and determining their relationship with ischemic stroke and determining the measures that can be taken for future optimal treatment. We aimed to contribute to their approach.

Detailed Description
-----------------
Carotid web is a thin membrane-like tissue that extends from the wall to the lumen of the carotid artery bulb, identified radiologically. It is considered that stroke may be related to altered hemodynamics, blood stasis and fibrin-based clot embolization mechanisms in the distal carotid web. Radiologically, in DSA and CTA, there is a thin membrane-like intraluminal filling defect extending along the posterior carotid wall in oblique-sagittal sections and a corresponding defect in axial sections. It is seen as a thin septum; There is no study on its classification in the literature. Determination of the incidence of carotid web, determination of its relationship with ischemic stroke / TİA, Facilitating distinctions such as dissection etc. by making radiological classification is important in terms of increasing awareness on this issue and early diagnosis. Demonstrating the relationship between carotid webs, which are shown as a cryptogenic cause of stroke, and vascular risk factors and taking protective measures against them will be effective in preventing strokes. In our research, we aim to increase awareness on this issue by classifying the frequency of carotid webs and their radiological classification; We aimed to evaluate the clinical data and vascular risk factors of carotid web cases, determine their relationship with ischemic stroke, and determine the precautions that can be taken to contribute to future optimal treatment approaches.
