Clinical Research Of Surgical Treatment And Influencing Prognosis Factors Of Intracranial Aneurysms In Anterior Willis's Circulation

Objective: to probe the treatment and opportunities of aneurysms of anterior willis's circulation .To find all kinds of significantly statistical indexes by analyzing the multiple influencing factors of the prognosis after clipping aneurysms of anterior willis's circulation can be helpful to the surgical operation of anterior willis's circulation aneurysms, and also can help the patients obtain the best surgical results.Methods: The clinical data, surgical procedures, opportunities and complications of 110 cases with aneurysms in anterior Willis circulation from 2003 to 2006 were analyzed. The influencing factors such as: sex, age, the aneurysm rupture times, the time interval between the last aneurysm rupture and the surgical operation, the consciousness in admission,the pre-operational Hunt-Hess grading , the pre-operational CT scan,the aneurysm site,the largest diameter of aneurysm, ventriculostomy or not, were analysed with the patients' Glasgow outcome scale(GOS)by means of analysis model ,the new the statistical results were obtained.Results : According to Hunt-Hess Grading, there were 54 cases of grade â…  , 20cases of grade â…¡, 16 cases of grade â…¢ and 20 cases of grade IV in this group. All patients were diagnosed by DSA.50 aneurysms were in the posterior communicating artery(PCoA),40 in the anterior communicating artery(AcoA), 6 in the middle cerebral artery(MCA) , 10 in the anterior cerebral artery(ACA), 10 in the Aanterior...
