Spontaneous Intraoral Hemorrhage as Manifestation of Thoracoabdominal Aortic Aneurysm-Associated Disseminated Intravascular Coagulation: Case Report and Review

Abstract

Intraoral bleeding from the gingiva or alveolar mucosa is a common symptom in dental and oral surgery outpatients. The bleeding is relatively easy to control with professional dental treatment, because it is almost always from local causes, such as inflammation or application of extreme external force to the mucosa. Occasionally, persistent or intermittent hemorrhage refractory to treatment indicates a general hemostatic disturbance, including coagulation factor deficiencies, fibrinolytic defects, and platelet or vascular disorders.
