Anomalous External Carotid Artery-Internal Carotid Artery Anastomosis in Two Patients with Proximal Internal Carotid Arterial Remnants [PDF]

Korean Journal of Radiology, 2015
Two angiographic instances of anomalous external carotid artery (ECA) and internal carotid artery (ICA) anastomosis are described, each occurring at the C2-3 level and bearing remnants of proximal ICA. The ICA remnant of one patient (identifiable immediately upon bifurcation of the common carotid artery) was hypoplastic, and that of the other patient ...

Anomalous Cervical External Carotid Artery-Internal Carotid Artery Anastomosis Diagnosed Using Digital Subtraction Angiography: A Case Report

Cureus, 2023
Anomalous external carotid artery (ECA)-internal carotid artery (ICA) anastomosis is a rare variant of cervical carotid artery formation that forms an arterial ring in the cervical segment, and its embryological mechanism is still unknown.

European Stroke Organisation guideline on endarterectomy and stenting for carotid artery stenosis

European Stroke Journal, 2021
Atherosclerotic stenosis of the internal carotid artery is an important cause of stroke. The aim of this guideline is to analyse the evidence pertaining to medical, surgical and endovascular treatment of patients with carotid stenosis.

Internal carotid artery dissection [PDF]

Neurology, 2000
M. Besselmann, MD, B. Vennemann, MD, S. Lowens, MD, E.B. Ringelstein, MD, F. Stogbauer, MD, Munster, Germany A 61-year-old patient was admitted with spontaneous acute holocephalic headache and left hemiplegia. Results of initial cranial CT scan were normal, but CT angiography revealed an occlusion of the right internal carotid artery (ICA) about 1.5 ...

Recanalization of a large supraclinoid carotid aneurysm via elicited vertebral artery-internal carotid artery anastomosis: a case report.

Turkish Neurosurgery, 2015
Proximal ligation of the internal carotid artery (ICA) with high-flow bypass is one of the surgical strategies for treating large, unclippable ICA aneurysms. We encountered a rare case of recanalization of a large ICA aneurysm that disappeared after high-

Carotid Artery Stenting in Patients With Chronic Internal Carotid Artery Occlusion [PDF]

Journal of Vascular Surgery, 2021
The risk of ischemic stroke in patients with chronic total occlusion (CTO) of the internal carotid artery (ICA) on best medical treatment has been estimated to be 5.5% per year. The purpose of this study was to assess early and mid-term outcome of patients who underwent an attempt at transfemoral carotid artery stenting (CAS) for CTO of the ICA ...

Internal carotid artery agenesis: A case report and review of literature

The Neuroradiology Journal, 2017
Congenital agenesis of the internal carotid artery is a very rare anomaly. Intracranial circulation in the involved internal carotid artery territory is maintained by collateral circulation from the contralateral internal carotid artery through the ...

Evidence for Shear Stress–Mediated Dilation of the Internal Carotid Artery in Humans

HYPERTENSION, 2016
Increases in arterial carbon dioxide tension (hypercapnia) elicit potent vasodilation of cerebral arterioles. Recent studies have also reported vasodilation of the internal carotid artery during hypercapnia, but the mechanism(s) mediating this ...
