The structural properties of carotid arteries in carotid artery diseases - a retrospective computed tomography
1Department of Radiology, Ege University, Faculty of Medicine, Bornova/Izmir, Turkey.
Insights
Carotid artery diseases like aneurysms and dissections cause significant haemodynamic changes. These changes, particularly in internal carotid artery diameter, are detectable and important for understanding structural deterioration.
Area of Science:
- Vascular Surgery
- Radiology
- Biomedical Engineering
Background:
- Carotid artery diseases, including stenosis, dissection, and aneurysms, significantly impact cerebral blood flow.
- Understanding the haemodynamic alterations in these conditions is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To investigate the haemodynamic changes associated with stenotic, aneurysmal, and dissection of the carotid artery and its branches.
- To compare these changes between patients with normal carotid arteries and those with carotid artery disease.
Main Methods:
- Retrospective review of cranio-cervical CT angiography images.
- Analysis of patients diagnosed with carotid stenosis, dissection, or extra/intracranial aneurysms.
Main Results:
- Significant differences in carotid artery diameters (ICA, CCA, ECA) were observed between normal and diseased (aneurysm, dissection) groups.
- Murray's laws were found to be applicable, with significant differences in cosine values of angles between normal and aneurysmal patients.
Conclusions:
- Aneurysm presence significantly influences carotid artery remodelling.
- Murray's laws remain valid for detecting structural deterioration in carotid artery diseases.
- The findings have potential applications in artificial intelligence for disease detection.
Purpose:
Aim of the study was to find answers to the following questions: What haemodynamic changes may occur in patients with stenotic, aneurysmal, dissection of the carotid artery and its branches? How do these changes differ in patients with normal and carotid disease?
Material And Methods:
In order to achieve this aim, the cranio-cervical CT angiography images of patients who were referred to our clinic for any reason and received the diagnosis of carotid stenosis, carotid dissection, and extra or intracranial aneurysm were reviewed retrospectively.
Results:
Significant differences were detected in the carotid arteries of normal patients and those with aneurysm and dissection. When normal and aneurismal patients were compared, right and left ICA diameters (p = 0.000, p = 0.002, respectively), total ICA diameters (p = 0.000), carotid left Ø diameters (p = 0.026), right and left total Ø diameters (p = 0.024), and Murray's and our cosine values of Ø angles (p = 0.001 and p = 0.022, respectively) were found to be different. Also, in a comparison made between normal patients and patients with dissection, right CCA (p = 0.000), ICA (p = 0.001), ECA (p = 0.004) diameters, total CCA (p = 0.001), ICA (p = 0.009), and ECA (p = 0.003) diameters were also found to be different.
Conclusions:
This study showed that the presence of aneurysm plays an important role in the remodelling of the carotid arteries. Also, it is understood that Murray's laws are still valid for the detection of structural deterioration in carotid artery diseases. Hence, it is believed that these data can be used in artificial intelligence studies.
