Carotid endarterectomy for stenoses of twisted carotid bifurcations

World Neurosurgery, 2010
The twisted carotid bifurcation is a variant in which the ICA courses medially to the ECA. Because descriptions in the literature have been limited, we here document clinical features and surgical experience of CEA for cases of twisted carotid bifurcation.Seventy-five out of a total of 106 consecutive cases with surgically treated carotid stenoses ...

Carotid Bifurcation Geometry and Atherosclerosis

Angiology, 2016
Hemodynamic changes occurring at the initial segments of the arterial bifurcations appear to play an important role in the development of atherosclerotic plaque. Therefore, arterial geometry might be a potential marker for atherosclerosis. Considerable evidence suggests that geometry can influence local hemodynamics at the carotid bifurcation ...

FLOW IN THE STENOTIC CAROTID BIFURCATION

Advances in Bioengineering, 2002
The carotid artery bifurcation is prone to the development of atherosclerotic plaques, and is a site where the consequences of this development can be severe. The most immediate effects are changes in lumenal cross-section, volumetric blood flow, and forces on the wall. The end result may be plaque rupture, possibly resulting in a stroke.

Arteriography of the carotid bifurcation

Neurology, 1985
Atherosclerotic plaques may not be demonstrated adequately by standard anteroposterior (AP)-lateral projections of carotid arteriography. We evaluated selective carotid arteriography in oblique projections for 60 individual carotid arteries. Two neuroradiologists evaluated arteriograms in four separate sessions devoted to AP-lateral views alone and in ...

Surgical Results of Carotid Endarterectomy for Twisted Carotid Bifurcation

World Neurosurgery, 2019
The internal carotid artery is normally positioned posterolateral to the external carotid artery at the carotid bifurcation. An anatomic variation with the internal carotid artery positioned medial to the external carotid artery, the so-called twisted carotid bifurcation (TCB), is sometimes encountered in patients undergoing carotid endarterectomy (CEA)

Aneurysms of the bifurcation of the internal carotid artery

Acta Neurochirurgica, 1968
Thirteen cases of aneurysm of the bifurcation of the internal carotid artery are described. Clinical history, symptoms, angiographic aspects and surgical treatment are all described. Ten patients had an operation: 1 ligature of the carotid in the neck, 6 clipping and 3 ligature of the aneurysmal neck.

180-degre carotid bifurcation with an internal carotid artery aneurysm

Surgical and Radiologic Anatomy, 2023
Internal carotid artery (ICA) aneurysm is a rare pathology. In the clinical case we present, the patient had an ICA aneurysm as well as a rare anatomical variant of the carotid bifurcation.We present the case of a 45 year old man, who had two episodes of TIA revealed by loss of mind.

Ulcerative Lesions of the Carotid Artery Bifurcation

Archives of Surgery, 1963
Arterial lesions capable of producing transient episodes of cerebral dysfunction due to cerebrovascular insufficiency or the more lasting lesion, a brain infarct, may be found at any level of either the carotid or vertebral systems. Lesions of the extracranial portions of these systems have come under particular attention because their surgical relief ...

Surgery of the Carotid Bifurcation

1986
Approximately 75% of patients with an ischaemic stroke syndrome have at least one obstructive arterial lesion at an extracranial site1. By far the most important of these sites is the carotid bifurca¬tion and surgery of this area is considered in the present chapter.

Posterior projecting carotid bifurcation aneurysms

Journal of Clinical Neuroscience, 2009
Posteriorly projecting carotid bifurcation aneurysms are rare. Proximal anterior cerebral artery aneurysms are even more uncommon. Distinguishing between true posteriorly projecting carotid bifurcation aneurysms and carotid A1 aneurysms can be difficult but it is important because small posteriorly projecting carotid bifurcation aneurysms may need a ...
