The objective of this study was to determine whether computed tomography (CT) is a reliable method of imaging to assess placental injury after acute trauma during pregnancy.
This study was a retrospective review of digital CT images and electronically scanned charts of pregnant trauma patients identified from the hospital trauma registry list.
Using delivery within 36 hours of trauma as the clinical marker for the occurrence of placental abruption, positive radiologic readings showed 86% sensitivity and 98% specificity. The overall accuracy was 96%.
Given that defined patterns on CT can be identified and those can be correlated to actual abruption, CT may be a reliable method for evaluation of placental abruption after maternal trauma, especially in the face of abdominal trauma. Our results show that CT has both good sensitivity and specificity identifying abruption and should be considered for use in the management in the pregnant patient after trauma.
本研究旨在确定计算机断层扫描（CT）是否为一种可靠的影像学方法，用于评估孕妇急性创伤后胎盘损伤。
本研究为回顾性分析，从医院创伤登记列表中确定了孕妇创伤患者的数字 CT 图像和电子扫描图表。
以创伤后 36 小时内分娩作为胎盘早剥发生的临床标志物，阳性放射学检查结果显示出 86%的敏感性和 98%的特异性。总体准确率为 96%。
鉴于 CT 上可以识别出明确的模式，并且可以将这些模式与实际的胎盘早剥相关联，因此 CT 可能是评估母体创伤后胎盘早剥的可靠方法，尤其是在腹部创伤的情况下。我们的结果表明，CT 对识别胎盘早剥具有良好的敏感性和特异性，应考虑在创伤后孕妇的管理中使用。
