Outcomes of cell infusion for the treatment of neurological sequelae induced by spinal anesthesia-associated subdural hematoma: A case report

Background: Subdural hematoma following spinal anesthesia for cesarean delivery is a rare complication. Surgical removal of the hematoma is the standard treatment. However, there are still many patients who suffer permanent nerve damage of varying degrees after surgery. Cell therapy has recently shown great potential for treating nerve damage. Case presentation: This report described a case of paraplegia due to an epidural hematoma occurring after spinal anesthesia for cesarean section. The patient underwent surgery to remove the hematoma and rehabilitation afterward. However, no improvement was noted. Paralysis of the lower extremities associated with urinary retention and constipation persisted. The patient received three administrations of cell infusion: the first time with autologous bone marrowderived mononuclear cells and the following two with autologous adipose mesenchymal/stromal cells. After three cell infusions, the patient was able to walk and could urinate and defecate voluntarily. Sensory and motor function were improved and MRI showed a decrease in adherence of the nerve roots and spinal cord. Conclusions: Our results demonstrated that cell therapy may ameliorate paralysis of the lower extremities as well as fecal and urinary function following spinal hematoma associated with spinal anesthesia.
