  • Title: Recurrence and extension of lobar hemorrhage related to cerebral amyloid angiopathy: multivariate analysis of clinical risk factors.
    Author: Izumihara A, Suzuki M, Ishihara T.
    Journal: Surg Neurol; 2005 Aug; 64(2):160-4; discussion 164. PubMed ID: 16051011.
    Abstract:
    BACKGROUND: Many recent studies have analyzed clinical risk factors for the recurrence and extension of intracerebral hemorrhage. However, they have not been investigated in patients with lobar hemorrhage related to cerebral amyloid angiopathy (CAA). METHODS: We studied 40 surgically treated patients with lobar hemorrhage diagnosed histologically as being related to CAA. To determine clinical factors influencing the recurrence and hematoma size their clinical data (demographics, medical history, and radiographic and laboratory data) were examined retrospectively and subjected to multivariate analysis. RESULTS: Twelve patients (30%) had recurrent lobar hemorrhage. Twenty-one patients had a small hematoma and 19 had a large hematoma. Hypertension was the only significant clinical factor influencing the recurrence of CAA-related lobar hemorrhage. There was no significant clinical factor influencing the hematoma size of CAA-related lobar hemorrhage. CONCLUSIONS: The history of hypertension is associated with an increase in the recurrence of CAA-related lobar hemorrhage.
