They defined tortuosity as an S- or C-shaped elongation or undulation. Kinking was described as an acute angulation, its severity ranging from mild (angle ≥60°) to moderate (angle between 30° and 60°) and severe (angle <30°). Looping has been defined as an exaggerated S-shaped curve and Coiling as a circular course.

In one of the largest angiographic studies conducted by Weibel and Fields , internal carotid artery tortuosity and angulation, respectively, were observed in 35 and 5% of 1,438 consecutive patients. Tortuous vertebral, subclavian and lingual arteries have also been reported [13, 14, 15].
Are tortuous arteries normal?
Tortuous arteries and veins are commonly observed in humans and animals. While mild tortuosity is asymptomatic, severe tortuosity can lead to ischemic attack in distal organs.
