Abstract:

Objective To explore the clinical value of  digital subtractionangiography (DSA) and magnetic resonance angiography (MRA)  in diagnosis of cerebral vascular structural abnormalities in the  patients with spontaneous cerebral hemorrhage  in  subacute phase,and to provide clinical basis for detection of cerebral vascular structural abnormalities.Methods 183 patients with subacute spontaneous intracerebral hemorrhage within 1 week were selected,the vascular structures of the patients  were detected by DSA and MRA，and the influence factors were analyzed.Results The  DSA and MRA results showed that the  parietal lobe,frontal lobe,and lenticular nucleus had the largest incidence rates of spontaneous intracerebral hemorrhage,and accounted for 17.5%,16.9%,and 14.2%,respectively.he age and the incidence of the  hypertension of the  patients with cerebral vascular structural abnormalities were significantly lower than those of the patients without cerebral vascular structural abnormalities (P<0.05).There were positive correlations between subacute spontaneous cerebral hemorrhage and the age and the incidence of hypertension（r=0.43,r=0.46，P＜0.05）.The  rates of cerebrovascular alformation detected with  MRA and DSA had no  statistically significant difference.The DSA was regarded as detection gold standard,the sensitivites and specificities of   MRA  in detection of cerebrovascular malformation were 98.8% and 96.9%.Conclusion The abnormal vascular structures of patients with subacute spontaneous intracerebral hemorrhage  can be detected mostly by MRA and DSA.MRA has the advantages of non-invasion,which is worthy to be applied in clinic.
