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.
本文描述了一种动脉造影出血的新征象，即造影剂从出血血管选择性地进行舒张期清除。此征象的应用必须局限于快速出血的终末血管分布区域，或不存在未显影侧支循环的情况。不应将其与多支主干血管侧支循环区域内造影剂的正常廓清相混淆，在这些区域间歇性显影是正常特征。
