Use of recombinant human factor VIIa in 2 patients with postoperative noncompressible, abdominal hemorrhage

Abstract

Objective To describe the clinical presentation, clinical course, and successful management of noncompressible, abdominal hemorrhage with recombinant human factor VIIa (rFVIIa) in 2 postoperative patients. Case Summary A 14‐year‐old neutered female Border Terrier and a 9‐year‐old neutered male domestic shorthair were treated with rFVIIa to treat noncompressible abdominal hemorrhage in the postoperative period. The dog presented for a septic abdomen following endoscopic intestinal biopsies 10 days prior and was found to have a jejunal perforation along with a fractured liver lobe and hepatic lymphoma at the time of exploratory laparotomy. The cat presented for a spontaneous hemoabdomen associated with hepatic amyloidosis. Clinically significant hemorrhage occurred in the perioperative and postoperative period and both patients received massive transfusions and antifibrinolytic therapy. Despite these interventions, the patients continued to have ongoing abdominal hemorrhage and surgical attempts at hemostasis were not attempted due to the friable nature of the liver at the time of surgery. Both patients received rFVIIa intravenously every 3 hours at a dose between 70 and 90 μg/kg as indicated by the clinical picture, which subsequently decreased transfusion requirements. New or Unique Information Provided This case report describes the use of rFVIIa in a cat and a dog with severe, noncompressible abdominal hemorrhage in combination with standard hemostatic interventions.
