Abstract

CASE DESCRIPTION

An 11-month-old mixed-breed dog was evaluated because of a 2-day history of acute-onset, intermittent vocalization and collapse several days after ingesting metallic wire foreign material.

CLINICAL FINDINGS

Physical examination findings were initially unremarkable. After a brief period of hospitalization, the patient acutely developed non-weight-bearing lameness with signs of severe pain localized to the left thoracic limb and inability or refusal to rise. Results of cervical, thoracic, and abdominal radiography revealed a linear metallic foreign body at the thoracic inlet and a single metallic foreign body in the cranial aspect of the abdomen. Neuropathic pain at the level of the left brachial plexus was suspected. Results of a subsequent CT scan were consistent with a metallic foreign body in the left axilla with associated abscess formation and neuritis and an additional metallic foreign body within the omental fat near the pyloroduodenal junction.

TREATMENT AND OUTCOME

Intraoperative fluoroscopy was used to facilitate localization and surgical removal of the axillary foreign body. The intra-abdominal foreign body was removed laparoscopically. Complete resolution of clinical signs was observed before discharge from the hospital the following day. On telephone follow-up 8 months after surgery, the owners reported the patient had no signs of lameness or complications.

CLINICAL RELEVANCE

Migrating metallic foreign bodies may be identified as incidental findings with the potential to cause harm in the future or may be a cause for severe clinical signs. Migrating foreign bodies should be considered as a differential diagnosis for patients reported to have acute collapse or lameness and consistent clinical history.

Abstract

OBJECTIVE

To report the fluoroscopic removal or repositioning of urinary tract implants in dogs and cats by use of an endovascular snare system (ESS) and to report procedural usefulness and complications in dogs and cats.

ANIMALS

3 cats and 14 dogs.

PROCEDURES

A medical records review was performed to identify dogs and cats that underwent removal or repositioning of urinary tract foreign bodies or implants by use of an ESS with fluoroscopic guidance at a veterinary teaching hospital from 2013 to 2019.

RESULTS

Dogs had a median weight of 25 kg (55 lb) with a range of 3.5 to 60.6 kg (7.7 to 133.3 lb), and cats had a median weight of 5 kg (11 lb) with a range of 4.2 to 5.4 kg (9.2 to 11.9 lb). By use of an ESS, 12 patients (2 cats and 10 dogs) underwent transurethral retrieval of retained vesicourethral implants or ureteral stents, 2 dogs underwent transurethral ureteral stent repositioning, 1 cat and 2 dogs underwent transnephric retrieval of ureteral stents, and 1 dog underwent cystoscopic-assisted transureteral ureteral stent retrieval. All procedures were successfully performed, and there were no associated procedural complications.

CONCLUSIONS AND CLINICAL RELEVANCE

Retained vesicourethral implants or ureteral stents were successfully retrieved by use of an ESS in dogs and cats transurethrally or with an open or percutaneous transnephric approach and fluoroscopic guidance. These techniques should be considered as an alternative or adjunct to more invasive methods for implant retrieval or manipulation.
