Can I Haz Coagulopathy?

by Dr. Marjory BrooksDevon Rex cat

Two feline case studies from the Comparative Coagulation Lab

CASE 1

Signalment: 4-year -old, spayed female, Devon Rex cat

Presenting Complaint: Abnormal bleeding post-ovariohysterectomy

History: “Scheherezade” is a retired breeding female who was spayed prior to placement in a pet home. She was spayed uneventfully, however during recovery she developed bruising and active bleeding from her abdominal incision. The owner reports that Scheherezade’s father had prolonged post-op hemorrhage after his castration surgery and a more distant relative was transfused for severe anemia of unknown cause.

Diagnostic work-up: Blood samples are drawn for CBC, chemistry profile, and an in-house coagulation screen consisting of APTT (activated partial thromboplastin time) and PT (prothrombin time).

All CBC and chemistry values are within normal limits, however both the APTT and PT screening tests are prolonged.

Signalment: 5-month -old, intact male, DSH cat

Presenting Complaint: New kitten exam

History: “George” is a recently adopted stray kitten who presents for a physical exam, check for parasites, and vaccinations. The owner reports no problems and makes plans to have George neutered.

All CBC, chemistry values, and the PT are within normal limits, however the APTT screening test is prolonged.
