Successful xenotransfusion in a domestic ferret with spontaneous hemoperitoneum using feline packed red blood cells.

OBJECTIVE

To describe the diagnosis, management, and outcome of a ferret with spontaneous hemoperitoneum with surgical intervention and xenotransfusion of type A feline packed red blood cells (pRBCs).

CASE SUMMARY: A domestic ferret diagnosed with a spontaneous hemoperitoneum secondary to a hepatic mass received isotonic crystalloids, hypertonic saline, and an allogenic blood transfusion perioperatively. Postoperatively, the ferret developed progressive anemia and tachycardia refractory to fluid therapy and, given a lack of additional allogenic blood sources, received a xenotransfusion of feline pRBCs. The ferret was hospitalized for 4 days postoperatively and developed a presumed delayed transfusion reaction characterized by transient hyperbilirubinemia. At a 6-month recheck, the ferret was doing well clinically.

NEW OR UNIQUE INFORMATION PROVIDED: This is the first reported case of successful xenotransfusion of feline pRBCs in a ferret. Although xenotransfusion of ferrets with feline blood products is not recommended as a routine procedure, it remains a viable option in critical situations in which ferret blood is unavailable.
