Plain-English summary
A 4-year-old dog with acute kidney injury needed hemodialysis but experienced problems with the catheter used for treatment. The vet used a medication called tissue plasminogen activator to temporarily fix the catheter issue. Unfortunately, a postmortem examination revealed that a fibrin sheath, made of blood clots and tissue, had formed around the catheter, which contributed to its dysfunction. This case highlights that similar issues can occur in dogs undergoing dialysis, just like in humans.

Abstract
OBJECTIVE: To describe an intravascular fibrin sheath associated with a hemodialysis catheter in a dog. CASE SUMMARY: A 4-year-old dog presented for hemodialysis to treat acute kidney injury. Hemodialysis catheter dysfunction during the course of treatment was temporarily alleviated using a tissue plasminogen activator. A thrombus composed of fibrin and granulation tissue creating a sheath around the catheter and focally adherent to the vessel wall was identified on postmortem evaluation. NEW OR UNIQUE INFORMATION PROVIDED: Fibrin sheath formation is a commonly recognized problem of central venous catheters used for hemodialysis in people and is likely a common problem in veterinary patients undergoing dialysis as well. This report provides a description of the clinical features of the catheter dysfunction, response to treatment, postmortem radiographic and direct imaging, and histology of the fibrin sheath, and also provides a brief review of potential management techniques that have been described in people.
