Migrating foreign bodies is common in cats and dogs and can be challenging to retrieve. The aim of this study is to describe a minimally invasive ultrasound-guided technique for the removal of migrating foreign bodies.
Cases were retrospectively recruited from a single referral hospital. Soft tissue swelling with suspected abscessation was identified on CT and the presence of migrating foreign material was confirmed on ultrasound. Foreign body retrieval was performed under ultrasound guidance: a large bore cannula (14G) was placed in direct contact with the foreign body. A pair of 16G flexible grasping forceps was passed through the sheath of the cannula and the foreign material was grasped and removed. Follow-up was obtained via patient records or telephone conversation.
Seven dogs and one cat were included in this series. This technique was successful in removing foreign material from the neck (n = 4) and retro-bulbar area (n = 3). One retro-bulbar foreign body could not be safely removed due to its proximity to the globe. Median procedure duration was 20 minutes (range 5 to 35 minutes). Follow-up was available for seven cases at a median of 6 months (range 0.5 to 6 months). There was no recurrence of clinical signs in six out of seven cases. The swelling recurred at a different location in one case and no further foreign material was identified.
This technique enabled retrieval of migrating foreign material from the retro-bulbar and cervical regions. This was an efficient and minimally invasive technique that spared the need for surgical exploration.
异物迁移在猫和狗中很常见，取出异物可能具有挑战性。本研究的目的是描述一种用于取出迁移性异物的微创超声引导技术。
病例来自一家转诊医院，进行回顾性招募。在CT上发现疑似脓肿的软组织肿胀，并在超声上确认存在迁移性异物。在超声引导下进行异物取出：将一个大口径套管（14G）直接与异物接触放置。一对16G的柔性抓取钳穿过套管鞘，抓取并取出异物。通过患者记录或电话随访。
本系列纳入了7只狗和1只猫。该技术成功地从颈部（n = 4）和球后区域（n = 3）取出了异物。由于一个球后异物靠近眼球，无法安全取出。手术中位持续时间为20分钟（范围5至35分钟）。7例患者进行了随访，中位随访时间为6个月（范围0.5至6个月）。7例中有6例临床症状未复发。1例在不同部位出现肿胀复发，未发现其他异物。
该技术能够从球后和颈部区域取出迁移性异物。这是一种高效的微创技术，无需进行手术探查。
