The objective of this study was to assess the use of saline microbubbles as a sonographic contrast medium in monitoring abscess drainage. Seven abscesses were localized and drained with sonographic guidance. Four were in the brain and three were small abscesses in the liver, the subhepatic region, and the pancreas. After aspiration of the purulent material, irrigation with saline produced a highly echogenic sonographic pattern that was free of artifacts and distinctly different from the abscess contents and capsule, and the surrounding parenchyma. In one case, previously unsuspected loculation was detected, requiring repositioning of the needle for complete drainage. All abscesses were resolved and no untoward effects, such as sepsis, were encountered. In one additional patient, microbubble sonographic evaluation was used to monitor the progress of an abscess in which a percutaneous catheter was placed. Saline microbubbles may be used as a sonographic contrast medium to monitor sonography-assisted abscess drainage.
本研究的目的是评估盐水微泡作为超声造影剂在监测脓肿引流中的应用。在超声引导下对7个脓肿进行了定位和引流。其中4个位于脑部，3个为肝脏、肝下区域和胰腺的小脓肿。抽吸脓性物质后，用盐水冲洗产生了高回声的超声图像，无伪像，与脓肿内容物、包膜及周围实质明显不同。1例患者检测到先前未被怀疑的分隔，需要重新调整针的位置以实现完全引流。所有脓肿均已消退，未出现败血症等不良影响。在另外1例患者中，使用微泡超声评估来监测放置了经皮导管的脓肿的进展情况。盐水微泡可用作超声造影剂以监测超声引导下的脓肿引流。
