目的 探讨超声血管回声追踪(echo-tracking,ET)技术对猪肢体肌肉枪弹伤后伤侧髂外动脉弹性的检测价值.方法 应用二维超声及ET技术检测15只猪后肢肌肉枪弹伤后髂外动脉二维显像及弹性参数,并与伤前进行比较.超声检测后将实验动物处死,取髂外动脉行病理学分析.结果 肢体枪弹伤后,伤侧髂外动脉超声二维显像无明显改变;动脉弹性参数测值与伤前比较,弹性系数(Ep)、硬化参数(β)值增高,顺应性(AC)降低,差异有统计学意义(P<0.05);病理显示检测段动脉内弹力膜平坦、内皮细胞间断脱落、内皮细胞结构不清.结论 猪肢体肌肉枪弹伤后,ET技术能够敏感地反映邻近大动脉因间接损伤所致的弹性改变,从而可提示枪弹伤所致血管间接损伤的发生.
目的 探討超聲血管迴聲追蹤(echo-tracking,ET)技術對豬肢體肌肉鎗彈傷後傷側髂外動脈彈性的檢測價值.方法 應用二維超聲及ET技術檢測15隻豬後肢肌肉鎗彈傷後髂外動脈二維顯像及彈性參數,併與傷前進行比較.超聲檢測後將實驗動物處死,取髂外動脈行病理學分析.結果 肢體鎗彈傷後,傷側髂外動脈超聲二維顯像無明顯改變;動脈彈性參數測值與傷前比較,彈性繫數(Ep)、硬化參數(β)值增高,順應性(AC)降低,差異有統計學意義(P<0.05);病理顯示檢測段動脈內彈力膜平坦、內皮細胞間斷脫落、內皮細胞結構不清.結論 豬肢體肌肉鎗彈傷後,ET技術能夠敏感地反映鄰近大動脈因間接損傷所緻的彈性改變,從而可提示鎗彈傷所緻血管間接損傷的髮生.

Objective To explore the value of echo-tracking technique in the detecting the ipsilateral external iliac artery elasticity after gunshot wound in pig limbs.Methods Two-dimensional ultrasound imagings and elasticity parameters of external iliac artery of fifteen pig limbs were obtained respectively,and the results were compared with pre-injury groups.The animals were sacrificed after ultrasonography.Pathological examinations of adjacent external iliac artery of injured pig limbs were analyzed.Results Two-dimensional ultrasound imagings of external iliac arteries had no significant changes post-injury.The changes of elasticity parameters were significiant differences in the injured group comparing with the pre-injured group (P <0.05),including the increased stiffness parameter(β),pressure-strain elasticity modulus (Ep)and the decreased arterial compliance(AC).Pathological result showed that the internal elastic lamina of artery detected were flat,endothelial cells came off discontinuously and structure of them were undefined.Conclusions Echo-tracking technique can find the elastic changes of adjacent artery indirect injured by gunshot wound sensitively and which can suggest the occurrence of vascular indirect injury.
