Study on the result of DSA and CT for subarchnoid hemorrhage

objective:Study the value of DSA and CT examination for subarchnoid hemorrhage(SAH).Materials and Methods:80 cases,which were showed SAH and no hematoma in CT within 24 hours performed DSA. Results:In patients who suffered SAH only once,32 cases were diagnosed as cerebral aneurysm and 29 cases normal in DSA.While in petients who suffered SAH twice,all 19 cases were diagnosed as cerebral aneurysm.In this group,there were 16 cases whose second hemorrhage occurred 7-18 days after the onset of the disease.Conclusion:SAH patients diagnosed in CT should be performed DSA and the most appropriate time for DSA was within 6 days after the onset of SAH so as to diagnose and operate as soon as possible and decrease the mortality. the CT examination mostly showed positive within 24 hours after the onset of SAH,so it was not necessary to make a lumbar puncture.Besides this,the author also suggested that the hematocele zone could show the position of aneurysm.
