In cerebral amyloid angiopathy, the contractile elements of the leptomeningeal and cortical arteries are replaced by noncontractile amyloid beta protein. The incidence of amyloid angiopathy increases with advancing age. It is associated with Alzheimer's disease and spontaneous cerebral hemorrhage. The latter can have the characteristic acute computed tomographic appearance of a hematoma at the cortex-white matter junction with extension of blood into the subarachnoid, subdural, and intraventricular spaces. Multiple hemorrhages are frequent. Additional bleeding can occur after evacuation of the hematoma, and postoperative hemorrhage can occur after cortical biopsy. To elucidate the role of surgery in this condition, we have reviewed 20 consecutive operated cases of cerebral amyloid angiopathy. A first group of 8 patients with senila dementia underwent cortical biopsy without resultant hemorrhage. A second group of 6 patients in good clinical condition had delayed evacuation of a spontaneous cerebral hematoma from cerebral amyloid angiopathy because of the radiological misdiagnosis of a hemorrhage within a tumor. One patient died of a pulmonary embolism, and another had subsequent multiple hemorrhages that were ultimately fatal. A third group of 6 patients in poor neurological condition had the acute evacuation of a spontaneous cerebral hematoma to relieve intracranial hypertension. All died or were severely disabled. One had repeated hemorrhages which added a progressively more severe organic dementia onto an initial hemiplegia.(ABSTRACT TRUNCATED AT 250 WORDS)

Effects of YM-14673, a new thyrotropin-releasing hormone (TRH) analogue, on neurological deficits were observed in comparison with those of TRH and citidine diphosphate choline (CDP-choline) in rats with an experimental hematoma. Unilateral cerebral hematoma was prepared by injection of 0.25 ml of autologous blood into the region around capsula interna, putamen and caudate nucleus of the left cerebral hemisphere of the rats. The drug was administered once or multiple times a day immediately after the surgical operation for 7 days and measurement of neurological deficits was conducted every day for 7 days. Neurological deficits, such as hemiplegia, were observed maximally on the 3rd day after the operation and then gradually recovered in the saline-treated group. YM-14673 (0.1, 0.3 mg/kg i.p.) accelerated the recovery of neurological deficits. Single i.p. administration of TRH did not affect the neurological deficits; however, multiple administration (7 times a day for 7 days) of TRH accelerated the recovery of neurological deficits. CDP-choline, a cerebral metabolic enhancer, even in a dose of 300 mg/kg (i.p.) did not show any influence on neurological deficits. These results suggest that YM-14673 ameliorated neurological deficits in the cerebral hematoma models, presumably due to TRH-like activity. Possible mechanisms of the pharmacological actions of YM-14673 are also discussed.

We report the case of a 49 year-old man who presented a partial status epilepticus with left-sided clonic seizures after the occurrence of a left cerebral hematoma. The patient had left-side hemiplegia that progressively recovered in 3 months. Neuroimaging studies revealed a moderate cerebral atrophy on the right side and crossed cerebellar atrophy. Six years later, he had a partial status epilepticus with left hamiconvulsions leading to permanent left hemiplegia. The right cerebral and the left cerebellar atrophy observed one year later were significantly increased. Cerebral hemiatrophy associated with epilepsy in adulthood is exceptional. Our case suggests that the occurrence of partial status epilepticus, even during adulthood, may aggravate cerebral hemiatrophy formally silent.

Reports of intracerebral hemorrhage (ICH) in patients with hemophilia B are relatively rare. We describe the first clinical results of the use of a monoclonal antibody purified factor IX (FIX) concentrate (Mononine) after an ICH and the long-term outcome of prophylaxis with this product to prevent recurrences. A 44-year-old male with severe hemophilia B was referred to our department because of nausea, vomiting, left lower limb hemiplegia, and left arm paresis. Computed tomography (CT) revealed a right frontal intraparenchymal bleed. The patient was treated with replacement therapy with FIX for 40 days. Computed tomography scans performed on day 40 after the event showed complete disappearance of the cerebral hematoma from the parenchymal tissue. Subsequently, the patient received 25.6 IU/kg(-1) of FIX twice a week. At the 48-month follow-up visit, no more major or minor bleeding events had occurred. Long-term prophylaxis after ICH is recommended.
