数字减影血管造影对脑梗死患者颈部血管的诊断价值研究

目的:分析数字减影血管造影(DSA)对脑梗死患者颈部血管的诊断价值。方法:选取医院收治的30例行DSA诊断和介入手术治疗的脑梗死患者,所有患者均行CT血管造影(CTA)和磁共振血管造影(MRA)检查,分别比较DSA、CTA及MRA对颈部血管的诊断情况。结果:DSA对脑梗死患者颈部血管狭窄程度的检出率明显高于CTA检查,其差异有统计学意义(x^2=4.71,P<0.05)。DSA对脑梗死患者颈部血管狭窄程度的检出率高于MRA检查,其差异有统计学意义(x^2=8.44,P<0.05)。患者术后颈部血管狭窄率较术前明显下降,其差异有统计学意义(x^2=8.06,P<0.01),神经功能症状明显改善。随访3~24个月,患者均无颈部血管狭窄的发生,其中短暂性脑缺血发作2例,心肌梗死1例,发生新的梗死灶4例,死亡1例。结论:DSA对脑梗死患者颈部血管狭窄程度的检出率高于CTA及MRA检查,对术前诊断脑梗死患者颈部血管狭窄程度具有重要的评估价值;且经介入手术治疗后具有良好的临床疗效,可有效降低颈部血管狭窄率,减轻患者的神经功能症状。

The diagnostic value of DSA on cervical vessels of patients with cerebral infarction

Objective:To analyze the diagnostic value of digital subtraction angiography(DSA)on cervical vessels of patients with cerebral infarction.Methods:30 patients with cerebral infarction who underwent DSA diagnosis and received treatmentof interventional operation were selected.All patients were examined by computed tomography angiography(CTA)and magnetic resonance angiography(MRA).The diagnoses of DSA,CTA and MRA on cervical vessels were compared respectively.Results:The detection rate of DSA on cervical vascular stenosisof patients with cerebral infarction was significantly higher than that of CTA examination(x^2=4.71,P<0.05).And the detection rate of DSA on these patients was significantly higher than that of MRA examination(x^2=8.44,P<0.05).The rate of cervical vascularstenosis of patients post operation was significantly lower than that pre operation(x^2=8.06,P<0.01),and the symptoms of neurological function post operation were improved significantly.During the follow-up period of 3-24 months,cervical vascular stenosisdidn’t be found in all patients,while 2 cases were transient ischemic attack,1 case was myocardial infarction,4 cases had new infarctions and 1 case died in these patients.Conclusion:DSA has an important assessment value in preoperative diagnosis of cervical vascular stenosis of patients with cerebral infarction,and it has a good clinical effect after interventional treatment.It can effectively reduce the rate of cervical vascularstenosisand can relieve the symptoms of neurological functionof patients.
