Spinal subdural hematoma in a patient with immune thrombocytopenic purpura following microvascular decompression: a rare case report

Résumé fourni par la source

This article reports a case of spontaneous spinal subdural hematoma (SSDH) after brain surgery in a patient with immune thrombocytopenic purpura (ITP), reviews the relevant literature, and discusses the etiology, pathogenesis, and clinical features of SSDH in patients with ITP. A male patient in his early 50 s with an 8-year history of ITP and suffering from coexistent hemifacial spasm and trigeminal neuralgia underwent microvascular decompression in our department. His preoperative corrected platelet count was within the normal range. On postoperative day 2, the patient complained of acute low back pain and sciatica. Lumbar magnetic resonance imaging demonstrated an SSDH extending from L3 to L4 with a significantly decreased platelet count (30.0 × 10 9 /L). The pain was gradually relieved after 2 weeks of conservative treatment, and no neurological deficit occurred during the 1-year follow-up. Brain surgery may increase the risk of postoperative SSDH in patients with ITP. Clinicians planning brain surgery must conduct a rigorous assessment through detailed physical examination, laboratory tests, and medical history records and maintain perioperative platelet counts within the normal range to prevent various risks associated with spinal cord compression.
