目的 探讨三维能量多普勒血管成像(3D-PDA)技术在定量评估睾丸扭转中睾丸血流灌注改变的应用价值.方法 比较20条犬的睾丸在扭转术前、睾丸分别扭转180°、270°、360°、450°、540°术后即刻及扭转1、2、3、4、5、6h后睾丸三维灰阶、3D-PDA超声表现,观察分析双侧睾丸体积、血管指数(VI)、血流指数(FI)、血管-血流指数(VFI)等的变化.结果 睾丸扭转后VI、FI及VFI值分别为6.67±0.67至0.19 ±0.11、33.06±1.43至11.61 ±2.05、2.21 ±0.27至0.02±0.01,较对照组(7.30 ±0.61、35.70±1.35及2.61 ±0.25)明显下降(P＜0.05).扭转360°后VI、FI及VFI值分别为2.75±0.57至0.71±0.18、20.65±2.02至8.41 ±1.67、0.57±0.14至0.06±0.02,较扭转前(7.18 ±0.76、35.38±1.36及2.54 ±0.31)明显下降(P＜0.05).随着扭转角度和时间的增加,VI、FI呈逐渐降低趋势.结论 3D-PDA诊断睾丸扭转程度的特异性和敏感性高,为判断扭转睾丸的血流灌注改变提供了定量参数指标.

Objective To investigate the value of three-dimensional power Doppler angiography (3D-PDA) in quantitative evaluation of the testical blood peffusion in testicular torsion.Methods Grayscale and 3D-PDA ultrasonography were applied respectively in 20 dogs without and with testicular torsion for 180°,270°,360° and 540°,immediately and after 1,2,3,4,5 and 6 h.The testis volume,vascularization index (VI),flow index (FI) and vascularization flow index (VFI) were observed and analyzed.Results The VI,FI and VFI in the torsional testis were 6.67 ± 0.67 to 0.19 ± 0.11,33.06 ± 1.43 to 11.61 ± 2.05 and 2.21 ± 0.27 to 0.02 ± 0.01,respectively,significantly lower than in control group (7.30 ±0.61,35.70 ± 1.35 and 2.61 ±0.25 respectively,P ＜0.05).The VI,FI and VFI in the testis after 360° of torsion were 2.75 ± 0.57 to 0.71 ± 0.18,20.65 ± 2.02 to 8.41 ± 1.67 and 0.57 ± 0.14 to 0.06 ±0.02 respectively,lower than in control group (7.18 ±0.76,35.38 ± 1.36 and 2.54 ±0.31,P ＜ 0.05).With the increasing trend of torsional angle and the time,the VI,FI and VFI were gradually decreased.Conclusion 3D-PDA has high specificity and sensibility in judging the blood perfusion and distribution of the testicular torsion and provides objective quantitative parameters.
