The common carotid artery is the large artery whose pulse can be felt on both sides of the neck under the jaw. On the right side it starts from the brachiocephalic artery (a branch of the aorta), and on the left side the artery comes directly off the aortic arch.
-stenosis: abnormal narrowing of a blood vessel or other tubular organ or structure Greek στενός (stenós), narrow, short; + -σῐς (-sis), added to verb stems to form abstract nouns or nouns of action, result or process restenosis, stenosis: steth-of or pertaining to the upper chest, the area above the breast and under the neck
Stricture as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g. achalasia, prinzmetal angina); stenosis is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g. atherosclerosis). [4] The term coarctation is another synonym, [5] but is commonly used only in the context of aortic ...
Segments of the internal carotid artery, delineated on an MRA of the head.. The internal carotid artery is a terminal branch of the common carotid artery; it arises around the level of the fourth cervical vertebra when the common carotid bifurcates into this artery and its more superficial counterpart, the external carotid artery.
Vertebral artery dissection is one of the two types of cervical artery dissection.The other type, carotid artery dissection, involves the carotid arteries.Vertebral artery dissection is further classified as being either traumatic (caused by mechanical trauma to the neck) or spontaneous, and it may also be classified by the part of the artery involved: extracranial (the part outside the skull ...
Congenital diseases are medical conditions that are present at birth that may be associated with or inherited through genes. [16] Examples of congenital cerebrovascular diseases include arteriovenous malformations, germinal matrix hemorrhage, and CADASIL (cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy). [9]
Craniosynostosis where no extracranial deformations are present, is called non-syndromic or 'isolated' craniosynostosis. [6] When there are extracranial deformations present, for instance involving the limbs, heart, central nervous system or the respiratory tract, [ 12 ] you may speak of a syndromic form of craniosynostosis.
Typical findings on angiography include smooth wall segmental stenosis of multiple arteriessometimes with post-stenosis dilation or bleeding. [5] In cases involving small vessels, angiography is usually normal and a biopsy is needed to confirm the diagnosis. [ 5 ]
