To the Editor： In 2016, a 35-year-old Chinese man was admitted to our hospital who had experienced multiple thromboses for 9 years, severe fatigue, and oliguria for a total of 3 weeks. The patient had been diagnosed with pulmonary embolism and multiple deep vein thromboses at a local hospital 9 years ago. The patient was prescribed warfarin, and the international normalized ratio （INR） was maintained between 2.42 and 3.18. While laboratory findings revealed a prolonged case （77.8 s） of activated partial thromboplastin time （APTT） at that time, no further investigations were carried out and anticoagulation therapy for the patient was terminated alter 3 months.
