摘　　要：目的比较数字减影血管造影(DSA)及磁共振血管成像(MRA)检测老年复发性缺血性脑血管病(ICVD)患者的病变血管情况。方法对52例老年复发性ICVD患者[脑梗死(CI)41例,短暂性脑缺血发作(TIA)11例]行DSA检查,其中44例患者行MRA检查。结果52例ICVD患者中,DSA检出血管异常43例(82.69%),其中血管狭窄39例(75%),CI组31例(75.61%),TIA组8例(72.73%);动脉瘤2例;血管发育不良及变异各1例。44例患者中,MRA检出血管狭窄10例(22.73%),其中CI组8例(18.18%),TIA组2例(4.55%)。DSA对病变血管的检出率显著高于MRA(P<0.01);但DSA与MRA对CI组及TIA组血管狭窄的检出率比较差异无统计学意义。结论DSA与MRA均可发现老年复发性ICVD的血管病变情况,DSA检出的阳性率更高。二者均可为ICVD提供血管病变的可靠证据。Objective To compared the condition of DSA and MRA for detection the lesion vessels in elder patients with recurrent ischemic eerebrovascular disease （ICVD）. Methods 52 patients with ICVD, including 41 cases of cerebral infarction（CI） and 11 cases of transient ischemic attack（TIA） were detected by DSA, and the 44 cases of them were detected by MRA too. Results The vascular anomalies were detected in 43 cases（82.69% ） of the 52 patients by DSA. Among them, 39 cases （75%） had vascular stenosis, in which 31 cases （75.61%） were CI, and the other 8 cases （72.73%） were TIA. The aneurysrn were founfd out in 2 cases, and vascular dysplasia and variation were also found in each 1 case by DSA. The vascular stenosis were found in 10 cases （22.73%） of 44 patients by MRA, in which 8 cases （18.18%） were CI, while 2 cases （4.55%） were TIA. The detection rate of lesion vessels in DSA was significantly higher than that in MRA（P 〈0. 01 ）, while,there was no significant difference in the detection rates of vascular stenosis between the DSA and MRA. Conclusions Both of DSA and MRA are able to detect vascular lesion condition in elder patients with recurrent ICVD. DSA has higher positive rate of detection. Both of them can provide reliable information of vascular lesion of ICVD.
