Epidemiology of subarachnoid hemorrhage, patterns of management, and outcomes in China: a hospital-based multicenter prospective study.

Aims: To conduct a large-scale analysis on epidemiology, management, and outcomes of spontaneous subarachnoid hemorrhage (SAH), and to investigate the current situation of aneurysm obliteration in China.

Methods: A multicenter prospective cohort study involving 132 hospitals throughout China from September 2007 to August 2008 was conducted. A total of 651 patients with spontaneous SAH were evaluated.

[Acute ischemic stroke in the very elderly outcome and predictive factors].

Objective: To investigate the clinical characteristics, 3-month outcome and predictive factors in the very elderly patients with ischemic stroke.

Methods: A total of 305 acute ischemic patients aged 65 years and over were enrolled in the study. They were divided into two subgroups by age: 80 years old and over (n = 78), 65 - 79 years old (n = 227).

Continual transcranial Doppler in the monitoring of hemodynamic change following aneurysmal subarachnoid hemorrhage.

Aims: To analyze and compare the value of different treatment methods for acute aneurysmal subarachnoid hemorrhage (aSAH)-related vasospasm. Cerebral hemodynamic variables' changes were evaluated by transcranial Doppler (TCD) in aSAH patients within 14 days after onset.

Methods: Thirty aSAH patients were enrolled in the study within 72 h after onset.
