Summary

Definition

History and exam

Key diagnostic factors

  • presence of underlying disorders
  • oliguria, hypotension, or tachycardia
  • purpura fulminans, gangrene, or acral cyanosis
  • delirium or coma
  • petechiae, ecchymosis, oozing, or hematuria
More key diagnostic factors

Risk factors

  • major trauma/burn/organ destruction or sepsis/severe infection
  • severe obstetric disorders or complications
  • solid tumors and hematologic malignancies
  • severe toxic or immunologic reactions
  • major vascular disorders (large aortic aneurysms or giant hemangiomas)
More risk factors

Diagnostic investigations

1st investigations to order

  • platelet count
  • prothrombin time (PT)
  • fibrinogen
  • D-dimer/fibrin degradation products
  • activated partial thromboplastin time (aPTT)
  • imaging studies or other tests
More 1st investigations to order

Investigations to consider

  • thrombin time
  • factor V, VIII, X, XIII
More investigations to consider

Emerging tests

  • inflammatory cytokines
  • D-dimer (monoclonal antibody test)
  • antithrombin III
  • fibrinopeptide A (FPA)
  • prothrombin fragment 1 and 2
