A analysis of risk factors in anneurysmal cerebral vasospasm after subarachnoid hemorrhage / 中国神经精神疾病杂志

ABSTRACT

Objective To investigate the risk factors of aneurysmal subarachnoid hemorrhage (aneuryismal sub?arachnoid hemorrhage, aSAH) vasospasm (cerebral vasospasm, CVS) and provide the basis for the clinical prevention and treatment of CVS. Methods A retrospective analysis of clinical data was conducted on 255 cases aSAH patients receiving treatment between March 2012 and March 2014 in First Affiliated Hospital of Xinjiang Medical University Department of Neurosurgery, s treated. The clinical data included admission age, gender, ethnicity, history of hypertension, smoking his?tory, arterial tumor site, improved Fisher grading, admission Hunt-Hess grade, the dosage of Nimodipine, dehydrating agent, white blood cell count, blood glucose, blood lipids, blood calcium levels, platelet count. Univariate analysis and multivariate Logistic retrospective analysis were used to analyze the association between above-mentioned factors and the occurrence of CVS. Results A total of 73 cases developed CVS after aSAH and incidence rate of CVS was 28.6%. Uni?variate analysis showed that there were significant differences between patients with and without CVS in history of hyper? tension, smoking history, improved Fisher grade, admission Hunt-Hess grade, small doses of nimodipine, white blood cell count and blood glucose (P<0.05). The Logistic regression analysis showed that the history of hypertension, smoking history, improved Fisher grade, admission Hunt-Hess grade, a small dose of Nimodipine and white blood cell count were risk factors of CVS after aSAH (P<0.05). Conclusions the History of hypertension, smoking history, improved high Fish?er grade, high admission Hunt-Hess grade are independent risk factors of CVS after aSAH. A small dose of Nimodipine is a protective factor while increase in white blood cell count is a risk predictor, which should be controlled by enhancing clinical prevention.
