Extracranial carotid aneurysms are uncommon, and in the past their management has not always been satisfactory. These aneurysms may be caused by arteriosclerosis, infection or trauma, or they may be congenital. Neurologic symptoms are common. Surgery is recommended for symptomatic aneurysms in patients of all ages. Non-growing aneurysms in old patients can be conservatively managed. Six cases of carotid and one case of vertebral artery aneurysm are reported. The mode of clinical presentation, etiologic factors, angiographic findings and methods of management are discussed.

Introduction: Cardiovascular diseases affect 17.7 million people annually, worldwide. Carotid degenerative disease, commonly described as atherosclerotic plaque accumulation, significantly contributes to this, posing a risk for cerebrovascular events and ischemic strokes.

Background: Although mice are used extensively to study atherosclerosis of different vascular beds, limited data is published on the occurrence of intracranial atherosclerosis. Since intracranial atherosclerosis is a common cause of stroke and is associated with dementia, a relevant animal model is needed to study these diseases.
Methods And Results: We examined the presence of intracranial atherosclerosis in different atherogenic mouse strains and studied differences in vessel wall characteristics in mouse and human tissue in search for possible explanations for the different atherosclerotic susceptibility between extracranial and intracranial vessels.

Extracranial carotid artery aneurysm (ECAA) is a relatively rare vascular lesion of the neck, and is usually found incidentally and is usually asymptomatic. Surgery is currently the first choice for symptomatic or growing ECAA, including open resection of the entire aneurysm, with or without arterial replacement and insertion of grafts. Ischemic stroke is the most serious complication after resection of ECAA.

Purpose: This study aims to investigate the indications and therapeutic efficacy of flow-diverting stents (FDSs) in the management of extracranial carotid artery aneurysms (ECAAs) and dissections.
Methods: A retrospective analysis was conducted on 18 patients treated for ECAAs with an FDS between 2010 and 2024. Patient demographics, aneurysm characteristics, procedural details, and clinical and radiologic follow-up outcomes were extracted from medical records.

Background: Previous trials have failed to demonstrate the benefits of extracranial-intracranial (EC-IC) bypass surgery for patients with carotid or middle cerebral artery occlusion. However, little evidence has focused on the effect of age on prognosis. This study aimed to explore whether EC-IC bypass surgery can provide greater benefits than medical therapy alone in specific age groups.
