Abstract
Between 1984 and 1994, of the 375 patients admitted to our department for intracerebral hemorrhage (ICH), 24 (6.4%) had a recurrent ICH. There were 15 women and nine men and the mean age of the patients was 64.7 ± 9.4 years (range 49-81) at the first bleeding episode and 68.7 ± 7.5 years(range 57-83) at the second. The mean interval between the two bleeding episodes was 47.5 ± 30.5 months (range 3 months to 14.8 years). Nine patients presented with more than one recurrence of ICH. Seventy-one percent of the patients were hypertensive. The site of the first hemorrhage was lobar in 17 patients, ganglionic (putamen, thalamus, or caudate nucleus) in six patients, and subdural in one. The recurrent hemorrhage occurred at a different location from the previous ICH. The most common pattern of recurrence was "lobar-lobar" (14 patients) and more rarely"ganglionic-ganglionic" (five patients), which was always observed in hypertensive patients. The outcome after the recurrent hemorrhage was usually poor, with severe cognitive impairment. By comparison with 81 patients followed up to 24 months (47.9 ± 22.2 months) with isolated ICH without recurrence, only lobar hematoma and a younger age were risk factors for recurrences whereas sex and previous hypertension were not. The mechanisms of recurrence of ICH were multiple (hypertension, cerebral amyloid angiopathy). Control of blood pressure after the first hemorrhage may prevent ICH recurrences.
