Objective:

To explore value of digital subtraction angiography(DSA)in diagnosing ischemic cerebrovascu-lar disease(ICD)and evaluating therapeutic effect after intervention.

Methods:

Clinical data of 134 ICD patients treated in our hospital from Jan 2014 to Jun 2015 were retrospectively analyzed.All patients received magnetic reso-nance angiography(MRA),CT angiography(CTA)and DSA before intervention,and diagnostic value of three methods for ischemic cerebrovascular lesion were compared;stenotic degree of vessels and score of United States National Institutes of Health Stroke Score(NIHSS)were compared between before and after intervention.

Results:

A total of 1340 vessels were checked in 134 patients.DSA discovered 341 lesioned vessels(25.45%),25 completely occluded vessels(1.87%),153 vessels of 70% ~99% stenosis(11.42%),61 vessels of 50% ~69% stenosis(4.55%) and 102 vessels of <50% stenosis(7.61%);compared with CTA and MRA,there were significant rise in detection rates of lesioned vessels(21.19%,19.40% vs.25.45%),50% ~69% stenosis vessels(3.06%,2.54% vs.4.55%) and <50% stenosis vessels(5.67%,4.93% vs.7.61%)in DSA,P<0.05 or <0.01. A total of 109 patients with 120 vessels received intervention,compared with before operation,there were significant reductions in stenotic rates of extracranial artery[(83.51 ± 8.74)% vs.(22.87 ± 7.90)%]and intracranial artery[(81.63 ± 9.02)% vs. (19.64 ± 6.18)%]after intervention,P=0.001 both.Compared with before intervention,there was significant re-duction in mean NIHSS score[(14.68 ± 3.18)scores vs.(3.16 ± 1.94)scores]on three months after intervention, P=0.001.

Conclusion:

Detection rate of vascular lesion by DSA is significantly higher than those of CTA and MRA in ICD patients.Postoperative therapeutic effect assessment using DSA possesses high value,which is worth exten-ding.
