摘　　要：目的:探讨弹性超声及超声造影技术在输精管动脉阻断后睾丸血供变化中的应用价值。方法:选取11例行显微精索静脉结扎手术患者,测量阻断输精管动脉前后的弹性超声及超声造影值,阻断前后数据配对对照研究。结果:当输精管动脉阻断后,跨白膜区域及睾丸内部睾丸硬度均减少,其中跨白膜区域Ave由阻断前的11.44±2.52减低为阻断后的6.21±1.16(P<0.01),睾丸内区域Ave由阻断前的3.99±1.03减低为阻断后的3.27±0.70(P=0.012)。附睾部位的AUC由阻断前的80.98±60.74降低至阻断后的42.82±16.01(P=0.021),睾丸中央部的AWi值由阻断前的17.19±11.09降低至阻断后的11.03±8.58(P=0.034)。近白膜区域的各项数值在阻断前后均无统计学差异;附睾部位的Awi值及Awo值虽在阻断后降低但无统计学差异。结论:弹性超声及超声造影在睾丸不同血供状态的评估中有重要的作用。Objective:To explore the application value of elastic ultrasound(EUS)and contrast-enhanced ultrasonography(CEUS)in detecting the changes of testicular blood supply after blockage of the vas deferens artery.Methods:This study included 11 cases of microscopic varicocele ligation.We obtained the EUS and CEUS values of the patients before and after blocking the vas deferens artery and analyzed the data by paired comparison.Results:After the blockage of the vas deferens artery,the testicular hardness was reduced across the tunica albuginea and within the testis,with Ave decreased from 11.44±2.52 before to 6.21±1.16 after the blockage of the vas deferens artery across the tunica albuginea(P<0.01)and from 3.99±1.03 before to 3.27±0.70 after the blockage within the testis(P=0.012).The AUC in the epididymis was reduced from 80.98±60.74 before to 42.82±16.01 after the blockage(P=0.021),and the AWi in the central testis from 17.19±11.09 before to 11.03±8.58 after the blockage(P=0.034).No statistically significant differences,however,were observed in the values obtained close to the tunica albuginea or in the Awi and Awo in the testis after the blockage(P>0.05).Conclusion:Elastic ultrasound and contrast-enhanced ultrasonography play important roles in evaluating the changes of testicular blood supply in different states.
