摘要
为探讨二维超声应用于枪弹伤创伤弹道显像的价值 ,采用高频二维超声观测猪后肢软组织枪弹伤及其周围组织成像特点 ,并结合病理检查探讨其声学基础。结果发现 ,二维超声下 ,原发伤道形态有显著的特征 ,表现为走行清晰、内径不一、边缘不规整的管道状回声 ,而伤道内部回声随时间延长而呈动态变化。同时 ,伤道周围组织也表现出一定的声像图特点。研究表明 :二维超声显像能很好地分辨原发伤道、确定伤道的走向及分布 ,了解复杂伤道与毗邻组织脏器的关系 ,并可在一定程度上对伤道周围组织的损伤情况作一客观的评价 ,这对复杂伤道火器伤的治疗有重要的临床价值。
To explore the value of two dimensional ultrasonography used in gunshot wound, features of gunshot wound in pig thigh were studied by high frequency ultrasound and compared with pathologic examination. The primary wound tract showed remarkable features in ultrasonography with a cured anomalous pipelike image, which changed with time. Tissues around the wound tract also revealed some sonographic characteristics. The results indicate that two dimensional ultrasound can clearly manifest not only the shape and distribution of the wound tract, but also the relation between the tract and its adjacent tissues. Therefore, the method is of important value in treatment of gunshot wound.
