In blunt abdominal trauma, patients may still be actively bleeding despite being physiologically stable. Fast computed tomography scanning permits the detection of active haemorrhage by localising the site of extravasation of contrast enhanced blood. Though a specific sign of active bleeding, particularly arterial haemorrhage, it is insensitive to the slow, continuous venous oozing associated with retroperitoneal and pelvic skeletal injuries. However, its presence will have a critical influence on further surgical intervention. The imaging features of this uncommon entity are demonstrated in our case report.
在钝性腹部创伤中，尽管患者生理状态稳定，但仍可能存在活动性出血。快速计算机断层扫描能够通过定位对比剂增强血液的外渗部位来检测活动性出血。虽然这是活动性出血的一个特定征象，尤其是动脉出血，但它对与腹膜后和骨盆骨骼损伤相关的缓慢、持续性静脉渗血不敏感。然而，其存在将对进一步的手术干预产生关键影响。我们的病例报告展示了这一罕见情况的影像学特征。
