目的分析临床诊断为缺血性脑血管疾病患者的脑血管造影(DSA)结果,评估缺血性脑血管疾病行脑血管造影检查的价值。方法对来自2个中心的临床诊断为缺血性脑血管疾病的72例老年患者进行选择性全脑血管造影。所有患者局麻后,以Seldinger技术穿刺一侧股动脉,按常规给予全身肝素化并监测活化凝血时间(ACT),使ACT控制在250～300 s之间。结果72例患者中,DSA检出脑供血不足19例,脑梗死32例,短暂性脑缺血发作4例,总检出率为76．4％。其中61例患者同时进行动态增强磁共振血管造影(MRA),MRA显示血管狭窄15例(24．6％),DSA 46例(75．4％);两组比较,差异有统计学意义(P<0．01)。结论DSA检查对缺血性脑血管疾病患者的诊断具有重要价值,可以明确短暂性脑缺血和眩晕为首发症状患者的病因,有利于及时治疗。
Objective To analyze the results of cerebrovascular angiography (DSA) in patients with clinical diagnosis of ischemic cerebrovascular disease and evaluate the value of cerebral angiography in the diagnosis of ischemic cerebrovascular disease. Methods Selective whole cerebrovascular angiography was performed in 72 elderly patients with clinically diagnosed ischemic cerebrovascular disease from two centers. After local anesthesia in all patients, Seldinger technique was used to puncture the femoral artery and systemic heparinization was routinely performed and activated clotting time (ACT) was monitored to control ACT between 250 and 300 s. Results Of the 72 patients, DSA detected cerebral insufficiency in 19 cases, cerebral infarction in 32 cases, transient ischemic attack in 4 cases, the total detection rate was 76.4%. Sixty-one patients underwent dynamic contrast-enhanced magnetic resonance angiography (MRA) at the same time. MRA showed 15 cases (24.6%) of vascular stenosis and 46 cases of DSA (75.4%). The difference was statistically significant <0.01). Conclusion The DSA examination is of great value in the diagnosis of patients with ischemic cerebrovascular diseases. It can make clear the cause of transient ischemic attack and vertigo as the first symptom, which is beneficial to timely treatment.
