Severe bleeding or hemorrhage from an artery.
From arterio- (artery) + -rhagia (bursting forth or bleeding, from Greek rhegnynai to burst). Describes acute arterial bleeding. Medical emergency terminology.
Arteriorrhagia is an emergency because arterial bleeding doesn't trickle—arteries are under pressure, so blood sprays out rapidly, which is why even small arterial cuts can be life-threatening if not stopped immediately.
