Abstract

Objective: The aim of the study was to describe laparoscopic ultrasound (LUS) to guide microwave ablation (MWA) of hepatocellular carcinoma (HCC) in a dog.

Animals: A 13-year-old female spayed Husky.

Study design: Case report.

Methods: The dog was referred for laparoscopic MWA of a caudate lobe HCC measuring 2.7 cm × 1.9 cm× 2.3 cm. Laparoscopic ultrasound was used to guide percutaneous placement of a MWA probe within the caudate lobe mass. LUS was used to determine the tumor margins for placement of the probe within the medial and lateral aspects as well as the center of the mass. Additionally, LUS allowed visualization of vessels within the tumor so they could be avoided during probe placement.

Results: Safe ablation was accomplished, and the dog recovered uneventfully with no complications. Follow-up computed tomography (CT) 3- and 12-months postoperatively revealed complete ablation of the caudate lobe mass. However, progressive increase in size of the right medial lobe mass occurred. Right medial liver lobectomy was performed 13 months after MWA, with a histopathologic diagnosis of HCC. The dog was euthanized 777 days post MWA and 1445 days post initial left lateral lobectomy for HCC.

Conclusion: Laparoscopic ultrasound was useful in guiding complete and safe MWA of an HCC in this dog. Laparoscopic ultrasound should be considered when performing laparoscopic MWA of liver lesions in dogs.

腹腔镜超声引导下的狗肝细胞癌微波消融术。

研究目的该研究旨在描述腹腔镜超声（LUS）引导微波消融（MWA）治疗狗肝细胞癌（HCC）的方法：研究设计：病例报告：研究设计：病例报告：该犬尾状叶肝癌的腹腔镜 MWA 尺寸为 2.7 厘米 × 1.9 厘米 × 2.3 厘米。腹腔镜超声用于引导经皮将 MWA 探头置于尾状叶肿块内。腹腔镜超声用于确定肿瘤边缘，以便在肿瘤的内侧和外侧以及肿块中心放置探针。此外，通过 LUS 还可以观察到肿瘤内的血管，以便在放置探针时避开它们：结果：完成了安全消融，该犬恢复顺利，未出现并发症。术后 3 个月和 12 个月的随访计算机断层扫描（CT）显示尾状叶肿块已完全消融。但右侧内侧叶肿块逐渐增大。MWA 术后 13 个月进行了右内侧肝叶切除术，组织病理学诊断为肝癌。该犬在 MWA 术后 777 天和首次左外侧肝叶切除术后 1445 天安乐死：结论：腹腔镜超声检查有助于指导该犬完成安全的 HCC MWA。在对狗的肝脏病变进行腹腔镜 MWA 时，应考虑使用腹腔镜超声波。

期刊介绍： Veterinary Surgery, the official publication of the American College of Veterinary Surgeons and European College of Veterinary Surgeons, is a source of up-to-date coverage of surgical and anesthetic management of animals, addressing significant problems in veterinary surgery with relevant case histories and observations. It contains original, peer-reviewed articles that cover developments in veterinary surgery, and presents the most current review of the field, with timely articles on surgical techniques, diagnostic aims, care of infections, and advances in knowledge of metabolism as it affects the surgical patient. The journal places new developments in perspective, encompassing new concepts and peer commentary to help better understand and evaluate the surgical patient.
