Intrauterine fetal demise associated with consumption coagulopathy in a Douc langur monkey (Pygathrix nemaeus...

Intrauterine fetal demise was suspected in a Douc langur monkey based on measurements of declining urinary estrogen levels. Additional clinical evaluation by fetal cardiac auscultation, ultrasonic instrumentation, radiologic examination, and amniocentesis supported the diagnosis. Blood clotting studies demonstrated deficiency of factors consistent with a diagnosis of consumptive coagulopathy, a syndrome identical to that observed in man following prolonged intrauterine fetal demise.
