The terminal segment of each internal carotid artery
gave off the caudal communicating artery, the rostral cerebral artery, the middle cerebral artery, and the rostral choroidal artery.
Furthermore, when the patients were divided into two groups based on the presence or absence of internal carotid artery
plaques, the group with internal carotid artery
plaques had significantly higher values for Fontaine class, ultrasonic score, and number of occluded segments in the lower extremities (P< 0.001; Table 5).
Bilateral retropharyngeal internal carotid artery
: A rare and potentially fatal anatomic variation.
Covered stent-grafts for treatment of lacerations and pseudoaneurysms of the extracranial internal carotid artery
caused by penetrating injury are strongly preferred over non-covered stents.
Bilateral spontaneous internal carotid artery
dissection managed with endovascular stenting--A case report.
Surgery of these tumors can be challenging and used to be associated with significant mortality and morbidity because of their vascularity, involvement of internal carotid artery
and proximity to cranial nerves.
As anterior clinoid process covers the roof of cavernous sinus and the paraclinoidal segment of the internal carotid artery
, anterior clinoidectomy becomes mandatory in approaching cavernous sinus and in optic canal decompression so the parameters measured in the present study will guide in the careful dissection in that area.

Note the occlusion of the left internal carotid artery
, starting at the level of the common carotid bifurcation (a), in the neck (b), and in the carotid canal (c).
The C6 and C7 segments of the left internal carotid artery
(ICA) also showed high-grade stenosis (Figure 2(a)).
Carotid artery injuries (CAI) constitute approximately 22% of all cervical vascular injuries (CVI) and out of this percentage common carotid artery injuries (CCAI) constitute roughly 75% while internal carotid artery
injuries (ICAI) constitute roughly 20% [5-7].
Previous studies showed that a 90% carotid stenosis can reduce the ipsilateral central retinal artery perfusion pressure by approximately 50% [1-4] and as the degree of internal carotid artery
(ICA) stenosis increases, the flow in ophthalmic artery decreases.
The word "web" was firstly used by Momose and New to analyze the causes of nonatheromatous stenosis in the internal carotid artery
(ICA) in 1973 .
The decision to perform revascularization in patients with carotid artery stenosis and the choice of treatment depends on several criteria including: severity of internal carotid artery
stenosis, age, sex, comorbidities, life expectancy and complication rate [1, 3, 4].
