IntroductionBleeding may interfere with the visual field and create difficulties in performing the intended treatment, especially in operations involving a small working space such as endoscopic spinal surgery. Therefore, it is important to reduce the risk of bleeding before surgery.Patient ConcernsA 76-year-old female presented with a history of right anterior thigh pain along the L3 dermatome for 3-years, following a L3 compression fracture. In addition, the patient had developed autoimmune hepatitis at 50 years of age, and the platelet count on laboratory blood collection was 78 × 109/L.DiagnosisMagnetic resonance (MR) images showed a narrowed foramen at the L3-4 level. L3 nerve block was effective. L3 foraminal-stenosis was suspected.InterventionsMicro-endoscopic laminectomy (MEL) for foraminal decompression was planned due to possible L3 nerve root compression. Lusutrombopag, a thrombopoietin (TPO) receptor agonist, was orally administered for 7 days starting 7 days preoperatively to address the risks of bleeding.OutcomesThe patient successfully underwent MEL without any adverse events or complications.ConclusionThe results obtained from the use of lusutrombopag suggested that safety measures could be implemented preoperatively, and that lusutrombopag may be a useful supplemental drug for minimally invasive treatment of patients with cirrhosis and thrombocytopenia.Copyright © 2021 the Author(s).
