Purpose: To report the ophthalmologic symptoms and signs associated with extracranial internal carotid artery dissection.
Methods: One hundred forty-six consecutive patients with extracranial internal carotid artery dissection were evaluted; 29 were studied retrospectively from 1972 to 1984 and 117 prospectively from 1985 to 1997.
Results: Sixty-two percent of patients (91/146) with extracranial internal carotid artery dissection had ophthalmologic symptoms or signs that were the presenting symptoms or signs of dissection in 52% (76/146). Forty-four percent (65/146) had painful Horner syndrome, which remained isolated in half the cases (32/65). Twenty-eight percent (41/146) had transient monocular visual loss, which was painful in 31 cases, associated with Horner syndrome in 13 cases, and described as "scintillations" or "flashing lights"-often related to postural changes or exposure to bright lights-suggesting acute choroidal hypoperfusion in 23 cases. Four patients had ischemic optic neuropathy; one had diplopia. Among the 76 patients with ophthalmologic symptoms or signs as the presenting features of carotid dissection, a nonreversible ocular or hemispheric stroke later occurred in 27, within a mean of 6.2 days (range, 1 hour to 31 days). Eighteen patients had a stroke within the first week after the onset of neuro-ophthalmic symptoms and signs, and 24 had a stroke within the first 2 weeks.
Conclusion: Ophthalmologic symptoms or signs are frequently associated with and are often the presenting features in internal carotid artery dissection. Painful Horner syndrome or transient monocular visual loss should prompt investigations to diagnose carotid artery dissection and begin early treatment to prevent a devastating ocular or hemispheric stroke.

This study aimed to analyze the clinical characteristics and prognosis of Takayasu's arteritis (TA) with carotid artery occlusion in children. This study collected clinical data and follow-up information on the first diagnosis and treatment of c-TA combined with carotid artery occlusion in pediatric patients at the Children's Hospital affiliated with the Capital Institute of Pediatrics and Inner Mongolia Medical University Affiliated Hospital from 2013 to 2023. This study included four female patients with a mean age of (13.

Introduction: More and more evidence suggesting that internal carotid artery stenosis is not only a risk factor for ischemic stroke but also for cognitive impairments. Hypoperfusion and silent micro emboli have been reported as the pathophysiological mechanisms causing cognitive impairment. The effect of carotid artery stenting (CAS) on cognitive function varied from study to study.

The clinical image illustrates an unusual case of a patient with bilateral carotid artery dissection caused by compression from elongated styloid processes. In this case, the diagnosis was overlooked eight years earlier. Eagle's syndrome, marked by an elongated styloid process, can result in cervical artery dissection, highlighting the significance of recognizing this correlation in recurrent cases, which occur more frequently than idiopathic ICA dissections.

Purpose: Patients with contralateral carotid artery occlusion (CCO) represent a subgroup of patients at risk for revascularization procedures. The choice of appropriate revascularization procedure (carotid endarterectomy (CEA) or carotid artery stenting (CAS)) in these patients is controversial. The aim of this study is to share the results of clinical and radiological follow-up after CAS in these patients and to contribute to the literature by evaluating the efficacy and safety of stenting.

Background: The integration of robotics into neuroendovascular surgery has the potential to revolutionize the field by enhancing precision, reducing procedure-related risks, and improving patient outcomes. The CorPath GRX system represents a significant advancement in this domain. In this systematically conducted scoping review, we explore the current applications, advances, and challenges associated with robot-assisted neuroendovascular surgery.
