Which disorder is a systemic thrombohemorrhagic condition characterized by both excessive coagulation and excessive fibrinolytic activation?

• A. Cor Pulmonale
• B. Trismus
• C. Hepatojugular Reflex
• D. Disseminated Intravascular Coagulation (DIC)

Answer: (D)

Disseminated intravascular coagulation is a systemic thrombohemorrhagic process where widespread activation of coagulation creates microvascular clots throughout the body. That rapid clotting uses up platelets and clotting factors, causing a consumption coagulopathy and a tendency to bleeding. At the same time, the body increases fibrinolysis to break down these clots, producing products that further impair coagulation and promote bleeding. The result is both extensive clotting and bleeding, often with organ dysfunction from microthrombi. Clinically you’d see bleeding in someone who is critically ill or has a triggering condition (like severe infection, obstetric emergency, trauma, or cancer), along with signs of organ impairment from the clots. Lab tests typically show prolonged clotting times (PT and aPTT), low platelets, low fibrinogen, and a high D-dimer due to fibrin breakdown. Management centers on treating the underlying cause and providing supportive care to replace depleted factors as needed (for example, platelets, plasma, or fibrinogen-containing products). Anticoagulation is not routine and is considered only in specific scenarios where thrombosis dominates and bleeding is controlled.
