RESUMEN
Rivaroxaban, a factor Xa inhibitor, is one of the newly developed direct oral anticoagulants (DOAC). In recent times, it has been increasingly used in the prevention of pulmonary embolism in patients undergoing orthopedic surgery. This report describes a case of epidural hematoma in an elderly patient who underwent combined spinal epidural anesthesia for total knee arthroplasty; the patient received rivaroxaban postoperatively for 7 days to prevent pulmonary embolism. Additionally, the epidural hematomas developed on the 5th postoperative day but the patient recovered well with conservative treatment. Although rivaroxaban has a low need for monitoring and is easily administered, the guidelines should be carefully checked for the postoperative administration schedule in patients undergoing regional anesthesia. In addition, rivaroxaban should be used with caution, especially in elderly patients.

Although spinal anesthesia is one of the most reliable anesthetic techniques in clinical practice, failures may occur in daily practice at rare occasions. Their causes are diverse and they include anatomical structural variations. In particular, postoperative anatomical changes often occur in patients who have undergone spine surgery and may cause failures of spinal anesthesia. Postoperative pseudomeningocele constitutes extradural cerebrospinal fluid collected from a dural tear and it is considered a very rare complication of spine surgery. We describe the case where a patient with unexpected postoperative iatrogenic pseudomeningocele received lower extremity surgery under spinal anesthesia.
