The prevention of pneumothorax after percutaneous lung biopsy is a major patient safety concern. The insertion of hydrogel plugs into biopsy sites to mitigate this complication is a new intervention. The histology of the plug has not been previously reported, and in this study the histologic reaction is reported in 13 cases. The hydrogel plug forms a spherical basophilic matrix pool with an adjacent foreign body giant cell reaction and patchy eosinophilia. No extension to the pleural surface is present. The potential diagnostic errors related to the presence of the plug are discussed.
经皮肺活检后气胸的预防是患者安全的主要关注点。将水凝胶塞插入活检部位以减轻这种并发症是一种新的干预措施。塞子的组织学以前没有报道过，在这项研究中报告了 13 例的组织学反应。水凝胶塞形成一个球形嗜碱性基质池，伴有邻近的异物巨细胞反应和斑片状嗜酸性粒细胞增多。没有向胸膜表面延伸。讨论了与塞子存在相关的潜在诊断错误。
