Key result
Emergency administration of Vitamin K, FFP, recombinant factor VIIa, and PCC successfully reversed severe nicoumalone-induced over-anticoagulation (INR >27.5 to 0.97) for urgent surgery.
Why the study?
Over-anticoagulation with coumarins is not uncommon in poorly followed-up patients lacking regular INR monitoring, and various treatment options are available for emergency reversal alone or in tandem.

Case of extreme INR elevation with rupture underscores monitoring gaps in valve patients; leaves open optimal reversal strategies.
Over-anticoagulation with coumarins is not uncommon in poorly followed-up patients whose international normalized ratio (INR) is not regularly monitored. Various treatment options available for emergency reversal of over-anticoagulation are either used alone or in tandem. A 36-year-old female with a history of aortic valve replacement came with complaints of severe generalized abdominal pain and hematuria. Hemoglobin was 5 mg/dL, and the INR value was >27.5. Ultrasonography had left a ruptured hemorrhagic ovarian cyst with hemoperitoneum. With a hematology consult, various products were used to reverse the over-anticoagulation. Two liters of hemoperitoneum drainage and left salpingo-oophorectomy were done laparoscopically. Post-surgical recovery was unremarkable, INR was stabilized, and 2 days later, the patient was shifted to the ward. As an anesthetist and critical care physician, it is important to stabilize, optimize, diagnose, and treat these conditions with the aid of various other specialties in a limited amount of time to prevent adverse events that can be fatal.

Sarvesh et al. (2024) conducted a case report in Coumarin-associated over-anticoagulation with ruptured ovarian hemorrhagic cyst (n=1). Emergency rapid reversal (Vitamin K, FFP, recombinant factor VIIa, PCC) was evaluated on Reduction in INR. Emergency administration of Vitamin K, FFP, recombinant factor VIIa, and PCC successfully reversed severe nicoumalone-induced over-anticoagulation (INR >27.5 to 0.97) for urgent surgery.
