The diagnosis of Arterial Tortuosity Syndrome is established in a person with (1) generalized arterial tortuosity and (2) positive molecular genetic testing that identifies a pathogenic mutation in the SLC2A10 gene. [9]
As the arrangement of connective tissue is disturbed, the vessel wall is no longer able to hold its original conformation and begins to unravel due to the continued hypertension. High blood pressure mold and force the artery to now take on an elongated, tortuous course to better withstand the higher pressures. [citation needed]
Dieulafoy's lesion (French:) is a medical condition characterized by a large tortuous artery [2] most commonly in the stomach wall that erodes and bleeds. It can present in any part of the gastrointestinal tract. [3] It can cause gastric hemorrhage [4] but is relatively uncommon.
Prominent inferior labial artery, also known as caliber-persistent labial artery is characterized by the appearance of a pulsating papule in the lower vermilion, a centimeter of two from the oral comissure, formed by an especially tortuous segment of the inferior labial artery.
Atherosclerosis causes plaque to form within the carotid artery walls, usually at the fork where the common carotid artery divides into the internal and external carotid artery. The plaque build-up can narrow or constrict the artery lumen, a condition called stenosis. Rupture of the plaque can release atherosclerotic debris or blood clots into ...
Though it is usually associated with congenital heart diseases with decreased pulmonary blood flow, like tetralogy of Fallot or pulmonary atresia, it may be seen sometimes in isolation (i.e. not associated with any congenital heart disease). In the latter case, it is termed as isolated aortopulmonary collateral artery. [3]

Aberrant subclavian artery, or aberrant subclavian artery syndrome, is a rare anatomical variant of the origin of the right or left subclavian artery. This abnormality is the most common congenital vascular anomaly of the aortic arch , [ 1 ] occurring in approximately 1% of individuals.
