I understand your concern and would explain that considering the repeated lung infarction, it is important taking anticoagulation therapy warfarin in order to prevent future episodes of pulmonary embolism. I would also recommend performing a Doppler ultrasound of the leg veins in order to investigate for possible various veins and treat them if present. Hope to have been helpful! Wishing good health,
