【Abstract】 Objective To analyze the effect of digital subtraction angiography (DSA) in patients with acute cerebrovascular disease.Methods One hundred patients with acute ischemic cerebrovascular disease who underwent interventional surgery at Nanshi Hospital affiliated to Henan University were enrolled.DSA was applied during the operation and its application value was observed.Results Through DSA examination,84 patients with acute ischemic cerebrovascular disease were found to have vascular abnormalities,16 normal vessels (16.00%),6.00% for traffic aneurysms,and 54.55% for cerebral artery stenosis.The stenosis and occlusion of the patients after treatment were better than before treatment,and the difference was statistically significant (P<0.05).Conclusion DSA examination of acute ischemic cerebrovascular disease can significantly improve the detection rate of acute ischemic cerebrovascular disease,and the adverse reaction rate is low.

脑血管疾病大多数发病突然[1],如果不及时救治,会导致死亡,给患者的家庭和健康带来极大伤害,已成为社会共同关注的问题之一[2]。急性缺血性脑血管的患者会出现突发神经功能障碍,少数患者伴有突发的意识障碍等情况[3]。对缺血性脑血管病过去主要靠药物治疗,效果往往不够理想[4]。随着医疗技术的飞速发展和新型材料的应用,近年来研究发现,DSA这种新型技术受到了广大群众的认可,可明显提高了脑血管疾病诊断率,改善临床症状有较好疗效[5]。本文选取河南大学附属南石医院神经外科部分脑血管患者为研究对象,分析急性脑血管病患者介入过程中应用数字减影血管造影(DSA)的效果。
1 资料与方法
1.1 临床资料 研究对象为100例急性缺血性脑血管病于2014-02—2015-08在河南大学附属南石医院神经外科接受治疗的患者。男45例,女55例,年龄26~72(53.1±3.9)岁。患者符合脑血管病诊断标准且均经MRI及CT确诊,排除患有心肝肾脏器官方面的重大疾病和免疫性疾病的患者。
1.2 方法 患者在入院后经医生和仪器检查确诊,在手术治疗中介入DSA检查,如患者为血管狭窄和闭塞采用介入手术进行治疗。具体的DSA检查方法如下:将5F的猪尾导管放入患者的升主动脉内,将对比剂注入猪尾导管内,采集患者的头颅正位脑部图像,速度为6帧/s,直到采集出比较清楚在静脉窦时期的图像,然后选择DSA灌注图像的脑实质期。采集完图像后,行重建三维,得到重建的图像,从不同角度仔细观察血管狭窄情况。采用直径为10 mm的正圆形钢球测量患者的血管狭窄情况,依据患者的病变情况及图像种类调节钢球位置。
1.3 观察指标[6] (1)分析在DSA检查中100例急性缺血性脑血管病患者的类型及比例。(2)比较血管狭窄和闭塞患者在治疗前后血管狭窄程度的改变(主要包括血管面积的狭窄程度、血管直径狭窄程度、病变的长度及最小直径等)。
1.4 统计学处理 运用SPSS 17.0软件进行数据处理,计量资料以均数±标准差(x±s)表示,采用t检验,计数资料以率(%)表示,采用卡方检验,P<0.05为差异有统计学意义。
2 结果
2.1 DSA检查中急性缺血性脑血管疾病中的类型及比例 16例患者血管正常(16.00%),血管异常84例(脑动静脉畸形15例,脑动静脉畸形6例,大脑动脉狭窄54例,大脑动脉闭塞9例),大脑动脉狭窄占54.00%,交通动脉瘤占6.00%。
2.2 血管狭窄和闭塞患者治疗前后血管狭窄程度比较 治疗后患者血管狭窄和闭塞情况好于治疗前,差异具有统计学意义(P<0.05)。见表1、图1~5。

3 讨论
随着我国人口老龄化的日益增多,脑血管的发病率增加,且大多发病突然[7-8],给患者健康带来极大的伤害,已经成为社会共同关注的问题之一[9-10]。缺血性脑血管病的主要病症通常有头痛、意识模糊及偏瘫、失语[11-12]。缺血性脑血管病介入治疗的常见并发症有血压下降、高灌注综合征、缺血性卒中、动脉夹层形成、心肌缺血、血管痉挛、颅内出血等[13-14]。缺血性脑血管病出现后卒中或其他血管疾病的发生率明显增多。根据调查发现,缺血性脑血管病出现后2 d内有50%的患者出现脑卒中,5 a有1/3的患者脑组织内有大面积的阻塞[15-16]。以往主要靠药物治疗,但传统的药物很难治愈,效果不理想,所以快速正确的诊断对缺血性脑血病的及时治疗至关重要[17-18]。近年来研究发现,采用DSA介入手术治疗对重新建立缺血部位的血液循环,快速对病情做出有效的判断,为患者在最佳时期进行有效的介入治疗,改善临床症状有较好疗效。目前认为是诊断血管狭窄与闭塞的金标准[19-20]。本文发现,通过DSA检查发现血管异常患者84例,血管正常16例,交通动脉瘤占6.00%,大脑动脉狭窄占54.55%。在血管面积的狭窄程度、血管直径狭窄程度、病变的长度和最小直径方面,治疗后患者情况好于治疗前,差异有统计学意义(P<0.05)。经DSA检查治疗后,再进行手术治疗后取得良好的治疗效果,并发症发生率明显下降,表明通过DSA检查下,介入手术治疗过程应用DSA疗效显著。具体原因:(1)目前,急性缺血性脑血管病的检查方法较多,具体包括造影、超声、CT及DSA等。因受到仪器设备的精准度、仪器使用人员的操作技能等的影响,检查结果都会有些误差,从而影响医生的判断[21-23]。(2)外界因素不会DSA的检查,脑部血管中注入对比剂,根据人类脑部血管的流动性,DSA检查可收集到各个时期的脑部图像,根据收集的图像就可以辨别出发病的位置和病情进展程度,就可以对患者的病情做出判断和制定治疗方案[24-25]。(3)采用DSA辅助介入治疗脑血管疾病,可以将患者脑部血管情况清晰地呈现出来,进而可以快速发现病变位置,从而有效判断病情,提高了治疗的速度,为患者治疗节省了宝贵的时间。与KIDWELL等[26]的研究结论相似。
采用DSA对缺血性脑血管病患者进行诊断,取得良好的治疗效果,患者血管的狭窄程度改善,提升了患者的满意度[27-30]。
