Post-surgical hemorrhage: formation of a "liver clot" secondary to periodontal plastic surgery.

Bleeding is a common sequela of periodontal and oral surgery. Generally, bleeding is self-limiting. Special circumstances require additional procedures to reduce or eliminate active hemorrhage. Occasionally hemorrhage can be under control when a patient is dismissed from their surgical appointment and, subsequently, the patient will experience either slow seepage of blood or extravascular clot formation. This case report describes the unique formation of a "liver clot" or "currant jelly clot" following periodontal plastic surgery. The clotting cascade and common laboratory tests to evaluate bleeding disorders are also presented.
