Update of 156 Episodes of Central Nervous System Bleeding in Hemophiliacs


Update of 156 Episodes of Central Nervous System Bleeding in Hemophiliacs

M de Tezanos Pinto et al. Haemostasis. .


Between 1960 and 1991, 156 episodes of central nervous system (CNS) bleeding were documented in 106 patients from a total population of 1,410 hemophiliacs (7.5%). Ninety-one hemophilia A patients presented 131 bleeding episodes; 15 hemophilia B patients had 25 episodes. 32% of these episodes took place in patients less than 5 years of age. 46% were age 10 or less, and 72% were age 20 or less. The mean age was 14.8 years in hemophilia A and 9 years in hemophilia B patients. A significant increase in the mean age of hemophilia A patients has been observed over the last 10 years; this may be related to HIV infection. A history of recent trauma was documented in 39.7% of the episodes. Spontaneous CNS bleeding was predominant in severe hemophilia (85.2%). One hundred and fifty-four CNS bleeding episodes were intracranial and 2 intraspinal. Of the intracranial episodes, 37.7% were subarachnoid, 29.8 subdural, and 22.7% intracerebral. Factor VIII or IX inhibitors were present in 11.3% of the patients; this figure is slightly lower than that observed in our total hemophilic population. Over 50% of the patients had psychoneurological sequelae; the most frequent were seizure disorders and motor impairment. The overall mortality rate was 29.2%. The mortality was more closely related to the CNS bleeding site than to the severity of hemophilia. Treatment should be based on prompt and prolonged replacement therapy to ensure hemostatic levels of antihemophilia factors.
