摘要

本文介绍了一例 83 岁女性患者的病例，她强烈怀疑有活动性出血，但在原始计算机断层扫描（CT）中却看不到可诊断的对比剂红斑。教学要点：在进行静脉-动脉体外膜氧合（VA-ECMO）CT 血管造影时，了解血液动力学的改变非常重要，因为与血流相关的伪影（如血管分水岭现象）可能会掩盖出血。

Invisible Active Bleeding Due to the Watershed Phenomenon

A case is presented of an 83-year-old female patient with a strong suspicion of active bleeding, but no diagnostic contrast blush could be seen on the original computed tomography (CT) scan. Teaching point: When performing CT angiography in veno-arterial extracorporeal membrane oxygenation (VA-ECMO), it is important to understand the altered haemodynamics, as flow-related artefacts such as the vascular watershed phenomenon can obscure bleeding.
