This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Intra Uterine Growth Restriction, Intrapaum and Antepaum Fetal Surviellance, Subject name: Gynaecology & Obstetrics
A patient at 17 weeks gestation is diagnosed as having an intrauterine fetal demise on USG. She comes back to the OPD only after 5 weeks of the scan and has not expelled the fetus yet. She has had some occasional spotting. This patient is at increased risk for which of the following ? 
Select and explain. 
A. Septic aboion, B. Recurrent aboions in the future, C. Consumptive coagulopathy with hypofibrinogenemia, D. Rupture uterus
C: Consumptive coagulopathy with hypofibrinogenemia
Answer: C: Consumptive coagulopathy with hypofibrinogenemia 
Explanation: Consumptive coagulopathy with hypofibrinogenemia due to neglected missed aboion or neglected IUDs can trigger the coagulation cascade and consume the coagulation factors. Patient can go into DIC. This is an event related to actual consumption of procoagulants within the intravascular tree. This results in ineffective balance of natural anticoagulant mechanisms leads to widespread fibrin deposition causing multiorgan failure.
