Insights
A child with congenital heart disease developed severe bleeding after surgery due to a rare factor V inhibitor. This highlights the importance of considering acquired inhibitors in postoperative coagulopathy.
Area of Science:
- Cardiology
- Hematology
- Pediatric Surgery
Background:
- Congenital heart disease (CHD) presents complex surgical challenges.
- Acquired factor inhibitors are rare but critical complications.
Observation:
- A pediatric patient with CHD developed severe, unexplained coagulopathy post-surgery.
- The coagulopathy was linked to repeated exposure to bovine topical thrombin during the procedure.
Findings:
- The patient developed a specific acquired factor V inhibitor.
- This inhibitor was directly associated with bovine thrombin exposure, leading to severe bleeding complications.
Implications:
- Pediatric providers must consider acquired factor inhibitors in postoperative coagulopathy, especially after exposure to bovine thrombin.
- Early recognition and management of these inhibitors are crucial for patient outcomes.
- Reviewing treatment options for acquired factor inhibitors is essential for managing such rare cases.
Abstract:
Severe postoperative coagulopathy developed in a child with congenital heart disease due to a factor V inhibitor from repetitive exposure to bovine topical thrombin. This case report alerts pediatric providers to consider these inhibitors when postoperative coagulopathy occurs. Potential treatment options are reviewed.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized, and...
