[Study on recurrence of hypertensive intracerebral hemorrhage]

Abstract

Recurrence of hypertensive intracerebral hemorrhage confirmed by computed tomography scan has rarely been reported. The authors have experienced nine cases of recurrent hemorrhage among 494 cases of hypertensive intracerebral hemorrhage. Recurrence rate was 1.8%. There were eight males and one female with an average age of 60.5 years. Six cases had their first and second attacks in ganglionic regions. Among them, three cases had the second attack in the ipsilateral side, and the other three cases had the second attack in the contralateral side. Two cases had the first attack in the thalamic and the second in the cerebellar regions. One case had the first attack in the pontine and the second in the putaminal regions. Intervals between the first and second attacks were within 6 months for ipsilateral ganglionic attacks and over 4 years for contralateral ganglionic attacks. In all cases systemic blood pressure was normalized or well controlled by antihypertensive agents after the first attack. The mechanism of rebleeding has not been clarified.
