Spinal surgery in a patient with essential thrombocythemia resulting in leg paraplegia: a case report.

Abstract

Essential thrombocythemia (ET) is a chronic myeloproliferative disorder characterized by a relatively benign clinical course that may be complicated by conflicting thrombosis and bleeding. Postoperative spinal epidural hematoma is an uncommon, but well-known, complication after spinal surgery. To describe a patient with ET who underwent surgery for lumbar spinal canal stenosis resulting in leg paraplegia and discuss the perioperative management for ET. Case report. The patient with ET underwent laminoplasty and posterolateral fusion for degenerative spondylolisthesis and spinal stenosis at L4-L5. A hematoma was observed in the epidural cavity after surgery, and emergency surgical evacuation was performed. After revision surgery, bleeding from the wound continued for 2 months, despite transfusions of platelets and coagulation factors, and right unilateral leg paralysis developed. This case presentation increases the awareness of this disorder to the spinal community and the need to establish guidelines for the perioperative management of patients who require surgery in similar settings.
