A right eye amaurosis patient with congenital absence of the internal carotid artery

Congenital Absence (agenesis) of the Internal Carotid Artery

Agenesis of the internal carotid artery (ICA) is a rare congenital anomaly. Most of the patients are asymptomatic and it is usually discovered incidentally by computed tomography (CT) or magnetic resonance imaging (MRI). While collateral blood flow may allow these patients to remain asymptomatic, there is close association of the intra-cranial aneurysms and subarachnoid hemorrhage with ICA agen...

Report of a Variation of the Right Common Carotid Artery

Carotid artery is the most important artery that carries the major part of the blood supply to the head and neck. The branching of the common carotid artery usually occurs at the upper edge of the thyroid cartilage. The placement of carotid sinus has also increased its importance in this area. Considering the clinical importance of knowledge about carotid artery variations, this case is reporte...

Congenital absence of internal carotid artery: an unsuspected diagnosis.

To cite: Costa NR, Reis AM, Duarte D, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016218289 DESCRIPTION A man aged 56 years, with a history of moderate sensorineural hearing loss, presented with a fast progressing loss of hearing discrimination in his right ear. The audiogram confirmed the moderate sensorineural hearing loss with a speech discriminatio...

A Penetrating Pellet Jeopardizing Internal Carotid Artery

Carotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion

Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
