Postoperative Acute Spinal Subdural Hematoma: Report of Two Cases

Abstract

We report two very rare cases of postoperative acute spinal subdural hematoma (ASSH) and review the literature. ASSH is usually related to trauma or a previous lumbar puncture, and a review of the literature revealed only a few cases of spinal subdural hematomas occurring secondary to an underlying hematological disorder or to an iatrogenic coagulopathy. However, there have been no reports about the occurrence of ASSH as a complication of uneventful spinal surgery. The authors present two cases of postoperative ASSHs after open lumbar microdiscectomy (OLM) and underline the pitfalls in their diagnosis and treatment modalities. Two patients were treated with surgery, which progressed without sequelae, and their preoperative symptoms were resolved. Postoperative ASSH is an extremely rare complication, but precautions for meticulous hemostasis and careful awareness for minimal manipulation of the dura during lumbar surgery should be considered in all patients, even those who do not require multilevel decompressions and/or who have a preoperative coagulopathy.
