摘要
目的：探讨超声造影对腹膜后动脉损伤出血的诊断价值。方法：5只实验兔，直接穿刺法建立腹膜后髂外动脉活动性出血模型，创伤后2 min、10 min及40 min分别行超声造影观察，创伤后20 min、30 min两次行DSA检查，作为金标准评价损伤动脉出血情况。结果：动脉损伤2 min时行静脉造影检查，可动态观察造影剂自动脉破口处溢出至腹膜后呈“喷射状”，于动脉破口处测得高速血流，动脉损伤后10 min、40 min重复行静脉造影检查，仍可见造影剂自破口处渗出，但流速明显减慢，与DSA检查结果一致。结论：超声造影能准确显示腹膜后动脉活动性出血部位及流速，有较好的临床应用前景。
Abstract
Objective: To explore the value of contrast-enhanced ultrasonography(CEUS) in the diagnosis of retroperitoneal arterial hemorrhage. Methods: Five active bleeding sites were created in the external iliac artery of five rabbits. CEUS was used to observe the feature of active bleeding 2 min, 10 min and 40 min after the arterial injury. DSA was also used at 20 min and 30 min after the arterial injury, as a gold standard. Results: 2 min after the arterial injury, CEUS showed active bleeding sites with the feature of jet-like and high flow at the bleeding point. At 10 min and 40 min after the arterial injury, CEUS showed the feature of seeping-out and lower speed flow than before. The results were consistent with DSA. Conclusion: CEUS can display active bleeding of retroperitoneal arterial injury, and it will have good prospects for clinical application.
