title: Arteriographic bleeding: a new sign.
abstract: A new sign of arteriographic bleeding, diastolic clearance of angiographic contrast medium selectively from the bleeding vessel, is described. The use of this sign must be confined to rapidly bleeding end-vessel distributions or when nonopacified collateral circulation is not a consideration. It should not be confused with the normal washout of contrast substance in areas of multiple parent vessel collateral circulation where intermittent opacification is a normal feature.
