Clinical teaching and practical ideas for your next study session.
Acute Cholangitis on Warfarin: Separate Drainage From Sphincterotomy
With obstructed cholangitis and an INR of 3.2, the key procedural question is whether urgent duct decompression can be separated from sphincterotomy and stone extraction. Stent-only ERCP may be appropriate when the patient’s condition, anticoagulation, and technical feasibility favor staging—but the INR and procedure plan both need context.
Esophageal Cancer Work-up on Warfarin: Biopsy vs EUS-FNA
For progressive dysphagia in a patient with a mechanical mitral valve, distinguish diagnostic biopsy from EUS-guided sampling before deciding whether to interrupt warfarin.
INR 11.2 Without Bleeding: Safe Warfarin Reversal Without Overcorrection
An INR above 10 is a management threshold, not a cue for indiscriminate reversal. Learn how to confirm truly absent bleeding, consider low-dose oral vitamin K, monitor the response, and restart anticoagulation safely.
