Disseminated intravascular coagulopathy: Manifestations after a routine dental extraction

https://doi.org/10.1016/j.tripleo.2004.08.017Get rights and content

Clinical signs and symptoms of acute disseminated intravascular coagulopathy (DIC) include bleeding from body orifices, such as the nose, mouth, or ear, bleeding from an intravenous (IV) site, areas of ecchymosis, or blood in the urine or stool. The underlying disease triggering DIC usually determines the clinical presentation. However, patients with chronic DIC (compensated DIC) may possess subclinical signs and symptoms, and the bleeding disorder may only be identified through laboratory findings. In this compensated form, the triggering factor is exposed slowly and in small amounts (seen in malignancies and vasculitis), allowing replenishing of the augmented factors by the liver, adequate reticuloendothelial clearance of fibrin degradation products, and increased production of platelets, which prevent secondary fibrinolysis and the signs of bleeding.1, 4 We report a case of an 82-year-old male who presented to the emergency room 24 hours after a routine dental extraction with bleeding from the tooth socket, severe hypotension, and presence of ecchymosis on his chest. Clinical and radiographic exam revealed multiple thoracic and abdominal aortic aneurysms, as well as infrarenal and iliac aneurysms, continuous oral hemorrhage, and a unique presentation rarely documented in the literature: a bleeding tooth socket as the initial clinical sign and presentation of DIC.

Case report

An 82-year-old Latin American male presented to the hospital emergency room (ER) status-post extraction of tooth #31. The patient had noted spontaneous bleeding from his gingiva 2 days prior to visiting his dentist for the extraction. His chief complaint upon reaching the emergency room was continued bleeding since the extraction. The patient's medical history was significant for hypertension and benign prostatic hypertrophy. He was taking fosinopril and terazosin, and had no known drug

Discussion

Disseminated intravascular coagulopathy has many etiologies. The Merck Manual10 describes 4 areas in which DIC may arise: infection (particularly from gram-negative organisms), obstetrics, malignancy (usually from adenocarcinoma of the pancreas or prostate), and shock. Disease processes of particular importance to dental professionals that may cause DIC include intravascular hemolysis, septicemia, and viremia.1, 6 In addition, DIC may also be seen in a compensated form in patients with

    The patient has remained free of adverse events and abnormalities at two years after the surgery. Disseminated intravascular coagulation is a hemorrhagic disease characterized by imbalanced blood coagulation [10], and it is broadly coagulation- or fibrinolysis-dominant based on the degree to which the coagulation and fibrinolytic systems are activated [11]. Although PLT sharply decreases in coagulation-dominant DIC, FDP and D-dimer mildly increase, FDP and D-dimer strikingly increase, and PLT slowly decreases in fibrinolysis-dominant DIC.

    Citation Excerpt :

    A hemorrhagic manifestation might be the only initial clinical marker of deteriorating compensated DIC rather than of typical acute DIC. To our knowledge, the present case is the first report of spontaneous intraoral hemorrhage directly resulting in a subsequent diagnosis of DIC, because the previously reported cases were diagnosed in the wake of persistent hemorrhage after therapeutic intervention or trauma10,11,22-28,33-36 or were recognized by systemic symptoms such as hypoxia, hypotension, or pyrexia with rigor in acute DIC with or without hemorrhage.29-32 Given that the underlying AA in our patient was inoperable and remained as the cause of chronic DIC, surgical intervention to remove the sequestra, in conjunction with improvement of the DIC in advance, was valuable, because it precluded the possibility of recurrent oral bleeding.
