Twisted blood vessels: symptoms, etiology and biomechanical mechanisms
HC Han - Journal of vascular research, 2012 - karger.com
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 …
