Spinal epidural haematoma in haemophilia A with inhibitors--efficacy of recombinant factor VIIa concentrate

Spinal epidural hematoma in a child with hemophilia A with high titer inhibitors and follow-up with prophylactic emicizumab: case report and literature review

Hemorrhage in the central nervous system is the most severe and debilitating manifestation affecting patients with hemophilia A. The spinal epidural space is the most unusual and clinically challenging site of central nervous system hemorrhage in hemophilia A. These patients often show insidious neurological signs and symptoms that delay diagnosis and treatment. We share our experience treating a 4-year-old male patient with severe hemophilia A and high titer inhibitors with a spontaneous spinal epidural hematoma. The patient presented initially with intense headache and neck pain. After blood tests and imaging studies, bypassing agent therapy with recombinant-activated factor VII was used until discharge; this was later replaced with emicizumab. After 18 months, the patient is without neurological sequelae and has not experienced subsequent bleeding episodes. We review the available literature and discuss the relevance of emicizumab compared with standard therapies in the context of spontaneous spinal epidural hematoma.

Conservative therapy for spinal epidural hematoma in a child with hemophilia A with high-titer VIII inhibitors

The occurrence of a spinal epidural hematoma in patients with hemophilia A with high-titer VIII inhibitors is extremely rare and intractable. A 15-year-old male patient presented to our institution with acute back pain and progressive sensorimotor disorder of the bilateral lower extremities. He had hemophilia A with high-titer VIII inhibitors and had experienced recurrent hemorrhagic episodes for many years. Prompt magnetic resonance imaging revealed a spinal epidural hematoma. We administered bypassing agent therapy with prothrombin complex concentrates and performed intensive neurological monitoring. The neurological dysfunction improved with days, and the patient recovered completely within 3 weeks. Magnetic resonance imaging 1 year later showed that the hematoma had been completely absorbed. Spinal epidural hematomas in patients with hemophilia A with high-titer inhibitors can be successfully treated using prothrombin complex concentrates. Multidisciplinary discussions based on intensive neurological monitoring should be performed as early in the clinical course as possible.

Spontaneous cervical epidural hematoma during pregnancy: case report and literature review

Spontaneous spinal epidural hematoma (SSEH) during pregnancy is rare and may result in permanent damage if not promptly treated. There were few studies discussing the etiology, presentation and treatment of SSEH during pregnancy. The authors describe a case of spontaneous cervical epidural hematoma during pregnancy, which was diagnosed by magnetic resonance imaging (MRI) and managed with surgical evacuation. A retrospective review of a case of spontaneous epidural hematoma of spine during pregnancy was performed. The clinical features, diagnoses, treatments and outcomes of all cases were analyzed. Precise diagnosis without delay and rapid surgical treatment are essential for the management of SSEH during pregnancy.

Spontaneous hematomyelia in a child with hemophilia A: a case report

Hemorrhagic complications in patients with hemophilia have been occasionally reported in the spinal column and the spinal cord. Treatment is based on prompt replacement therapy as the occurrence and development of neurologic dysfunction are related to the length of time between the onset of symptoms and the factor replacement. We report case of a 7-year-old hemophilic boy who presented with flaccid paraparesis resulting from thoracic hematomyelia. The patient showed gradual improvement on medical management with cryoprecipitate infusions. This case calls attention to the need for prompt diagnosis of rarely reported spinal hematomyelia based on clinical manifestations and radiologic features and highlights its management options in patients with hemophilia.

Spontaneous spinal epidural hematoma: analysis of 23 cases

BACKGROUND

Spontaneous spinal epidural hematoma is a rare but disabling disease. To explore its characters and find out what factors influence the prognosis, we gave a retrospective analysis of 23 patients in our department in the past 8 years.

METHODS

Spontaneous spinal epidural hematoma was diagnosed by taking MRIs of patients without surgical management or by histopathological examination. We registered patient's case history, laboratory examination, radiological image, treatment, pathological result, and prognosis after 3 months and gave them nonparameter analysis.

RESULTS

Primary neurological status and progressive intervals have correlation with prognosis (P< .01), and the latter less than 12 hours predict worse prognosis (P= .032). Spinal edema in MRI predicts pessimistic prognosis (P= .013). Long hematoma predicts worse prognosis (P= .02). Preoperative interval, emphasized by other authors, has no statistical correlation with prognosis in this study (P= .832). Finally, patients with a single hematoma or hematoma mingled with other spinal disturbance have the same prognosis (P= .065).

CONCLUSIONS

The primary neurological status, progressive interval, spinal edema, and size of hematoma will influence the prognosis of the patient with SSEH. The major treatment is surgical intervention, and it should be operated as soon as possible to avoid the aggravation of neurological status. Conservative treatment is not considered unless patient's neurological deficiency has relieved in the early period.

Spinal epidural haematoma in a patient with haemophilia B

Spinal epidural haematoma (SEH) is a rare complication in haemophiliacs. We report the case of a 17-year-old boy with severe haemophilia B who presented with acute onset of neck/back pain, walking impairment and urinary retention because of an extensive SEH. The haematoma was identified by magnetic resonance imaging of the spinal column. Prompt and aggressive treatment with factor IX concentrate led to complete recovery at 3 weeks. This case calls attention to the clinical manifestation, radiological features and management options of the rarely reported SEH in haemophiliacs. Despite evidence of extensive SEH, factor replacement therapy and a multidisciplinary team approach result in complete neurological recovery without the need for surgical decompression.
