Delayed Vasospasm After Aneurysm With the Standardization Treatment of Traditional Chinese Medicine

April 25, 2013 updated by: Guangzhou University of Traditional Chinese Medicine
Delayed vasospasm (DCVS) is the most serious complication of aneurysmal subarachnoid hemorrhage (aSAH) perioperative period ,the incidence rate up to 30% to 90%, and often can cause severe brain ischemia or brain damage of delayed ischemic and even lead to cerebral infarction, to be the main factor of deadly and severe disability . (aSAH) perioperative delayed vasospasm (CVS) is the bottleneck to restrict the long-term effect. Since there is no standard clinical treatment programs, limiting the advantages and characteristics of traditional Chinese medicine to play.Guangdong Provincial Hospital of TCM is the province's Medical Center encephalopathy, treated 100 brain aneurysm patients each year, more than 80 times craniotomies and surgical interventions , with a rich source of patiengs to carry out the study. In this study, on the basis studies on hemorrhagic stroke of a yin and yang syndrome and comprehensive treatment programe of the State 1995,the 15th research , in accordance with characteristics of the pathophysiology and understanding of cause and pathogenesis in aSAH perioperative period , through expert advice and review of the literature, under the guidance of Liu Maocai who isChinese medicine practitioners of Guangdong province , from diagnosis, diagnosis and treatment,prescription drugs, and other aspects of efficacy evaluation, developmenting a standardized treatment program of delayed CVS after aSAH . To evaluate the efficacy of the standardized program by prospective, randomized,controlled clinical trial,improving the postoperative results, reducting significantly the mortality and morbidity patients with cerebral aneurysms.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The incidence of DCVS after aneurysmal postoperative
Time Frame: 3 months
after 3-months chinese medicine treatment, through evaluating the incidence of delayed vasospasm after cerebral aneurysms , to assess the efficacy of Chinese medicine
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
