Successful treatment of acute subdural haematoma associated with severe bleeding disorder.

A 76-year-old man suffering from myelofibrosis with thrombocytopenia sustained an acute subdural haematoma with severe neurological deficit. He was treated initially by bedrest and dexamethasone. Craniotomy was contraindicated because his bleeding time exceeded 20 min in spite of multiple infusions of platelet concentrate. After 3 weeks his condition deteriorated with increase of the fluid collection shown by CT. Partial drainage of the haematoma by subdural puncture with a 22-gauge spinal needle resulted in complete recovery from the neurological deficit and complete resorption of the effusion. The case shows that it is possible to avoid craniotomy in the acute phase of a subdural haematoma in patients with bleeding disorders and that it may be advantageous to use needle evacuation instead of burr-hole drainage in the chronic phase.
