目的探讨腔内超声造影技术对常规超声下显示不清的引流管进行定位的价值.方法 26例患者共计32条留置的引流管引流不畅,常规超声无法清晰显示全程,经引流管注入稀释后的超声造影剂SonoVue对引流管进行观察,评价超声造影技术对引流管管体和引流管末端的显示能力,所需的检出时间,并判断有无脱管.结果常规超声检查对引流管管体和引流管末端的显示率分别为52.25%(18/32)和0,超声造影的显示率分别为100%和93.75%(30/32),两种方法的显示能力差异有统计学意义(P＜0.001).超声造影检查诊断其中3条引流管已脱管.超声造影检查所需时间的中位数为4.5 s(1～77 s).结论腔内超声造影技术是一种敏感、高效的引流管显示技术,弥补了常规超声检查的不足,可准确提供引流管信息,以协助临床医生对引流管的处理.

Objective To investigate the value of intra-cavitary contrast enhanced ultrasound(CEUS)in the location of drainage tubes which were unclear in conventional ultrasonography. Methods The locations of 32 drainage tubes in 26 patients were unclear in conventional ultrasonography. The diluted ultrasound contrast agent (SonoVue) was injected through the tubes. CEUS was used to evaluate the visualizations of the inner tubular portions and the distal ends. Whether the drainage tubes were in situ or not was also judged. The time-consumption of detection was counted. Results The percentages of the visualization of inner tubular portions and the distal ends in conventional ultrasonography were 52.25%(18/32) and 0,respectively. However,the percentages of visualization in CEUS were 100% and 93.75%(30/32), respectively. The difference were significant when compared conventional ultrasonography with CEUS ( P＜0.001 ). CEUS detected that three drainage tubes weren't in situ. And the median of timeconsumption of CEUS was just 4. 5 seconds (range: 1-77 seconds). Conclusions Intra-cavitary CEUS is a sensitive and high efficient technique in the visualization of drainage tube which may complement the insufficiency of conventional ultrasonography. It could be used as the first choice in the location of drainage tube.
