Haemorrhage involving the central nervous system in haemophilia: account of the management of five cases

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.

Laminoplasty preserving the deep extensor musculature for a pediatric cervicothoracic epidural hematoma case of hemophilia A

Postoperative malalignment after either a laminectomy or a laminoplasty in pediatric cases is a well-known complication. A 5-year-old boy with a history of hemophilia A presented with severe paresis. MRI showed an extensive epidural hematoma extending from C2 to T1. We performed decompression of the spinal cord using laminoplasty, preserving the insertion of the deep extensors. The patient completely recovered from the paresis. Even 7 years after the surgery we could not find any kyphotic deformities. The use of laminoplasty preserving the deep extensor musculature may be crucial for maintaining the postoperative cervical alignment in pediatric patients.

Conservative management of an acute spontaneous holocord epidural hemorrhage in a hemophiliac infant

Central nervous system hemorrhages are an uncommon but severe complication of hemophilia, occurring in only 2-8% of children with hemophilia. Less than 10% of these CNS hemorrhages are intraspinal. The authors report on their care of an infant with hemophilia A who presented with irritability, meningismus, and decreased spontaneous movement. These symptoms prompted imaging studies, which revealed a spinal epidural hematoma (SEH) extending from C-1 through the cauda equina. The boy was treated with factor replacement and close monitoring. Repeat radiographic imaging 14 days later demonstrated complete resolution, and the patient had returned to his normal baseline status. A literature review in the modern treatment era revealed 24 cases of SEH in children with hemophilia. Of these 24 cases, 11 underwent laminectomy and 13 received conservative treatment. All conservatively treated patients, 5 of whom had presented with weakness, experienced a full recovery. Of the 11 laminectomy patients, 10 presented with weakness and all but 3 experienced full neurological improvement. These 3 patients were notable for having previously undiagnosed hemophilia. An increased index of suspicion facilitates the essential management features of prompt diagnosis and correction of coagulopathies in children who present with SEHs. The authors apply a multidisciplinary approach involving a pediatric hematologist, neurosurgeon, and pediatric intensive care unit to ensure timely correction of the coagulation disorder, maintenance of adequate factor levels, and close hemodynamic and neurological monitoring. Observation with aggressive correction of coagulopathy is a reasonable treatment choice for hemophilic patients presenting with SEH and a stable neurological examination.

[Intracranial and spinal hemorrhage in haemophilia (author's transl)]

Among 234 hemophiliacs, 14 patients (5.9%) with intracranial and 1 patient (0.4%) with intramedullary hemorrhage were observed and examined. The average age at the time of hemorrhage was 17 years in patients with severe hemophilia and 43 years in patients with moderate hemophilia. The patients with mild hemophilia and intracranial bleeding were 5 and 58 years old, respectively. Eight intracerebral, 3 subdural and 4 subarachnoid hemorrhages were encountered. In 7 cases bleeding was posttraumatic and in 5 it occurred spontaneously. In 2 patients hemorrhage followed a sudden increase of intracranial pressure. In 1 patient reliable data could not be obtained. Four of the 8 patients with intracerebral bleeding died; all survivors displayed some residual neurological abnormalities. All patients suffering from subarachnoid bleeding recovered completely. No serious complications were encountered after 3 lumbar punctures, 5 cerebral angiographies and after 1 myelography. Only in 1 case with an acquired inhibitor did a local hematoma develop at the site of puncture for the angiography. The same diagnostic procedures should be performed after substitution therapy with anti-hemophiliac plasma in a hemophiliac without inhibitor as in non-hemophiliacs if intracranial or intramedullar bleeding is suspected. In hemophiliacs with an anticoagulant, angiography or lumbar puncture should be performed only in exceptional cases.
