目的应用超声造影观察肾挫裂伤和不同流速活动性出血,分析与肾创伤严重程度相关的因素.方法 4只健康杂种犬和6只新西兰兔开腹建立34处Ⅰ～Ⅴ级模拟钝性肾挫裂伤,分别进行二维和三维超声造影检查,观察创伤范围、部位、累及血管级别等情况,对伤情进行综合分类评估.结果二维和三维超声观察病灶的范围与大体标本具有一致性(长径F=0.4724,P=0.6252;横径F=1.6174,P=0.20490).三维超声造影能显示创伤累及的血管及相同范围的创伤灶,动物发生休克的时间不仅与创伤范围有关,还与创伤累及血管级别及伴发活动性出血的速度有关.结论超声造影能够客观地反映肾创伤程度,为临床采取治疗方案提供影像学依据.

Objective To explore contrast-enhanced ultrasonography (CEUS) in diagnosis renal injuries complicated with active bleeding of different velocity,and analysis the related factors of renal traumatic degree.Methods Thirty-four Ⅰ - Ⅴ grade lesions of renal injury were made in 4 dogs and 6 New Zealand rabbits.Two and three dimensional CEUS were used to observe traumatic extension,and traumatic position,involving in vascular as well.Then the injury condition was classified and assessed synthetically.Results The range of lesions observed by using 2D and 3D ultrasound had consistency with those of the pathologic sample (length-diameter:F =0.4724,P =0.6252; transverse diameter:F =1.6174,P =0.20490),3D-CEUS can display the vascular that involved by renal injury.In the same traumatic extension condition,the time of animal becoming shocked and injury severity was related to not only traumatic extension but also different velocity of active bleeding and involving in vascular.Conclusions Contrastenhanced ultrasound can objectively reflect renal injury severity,and more information can be provided to clinical for management.
