摘要
目的探讨头颈部CT血管造影(CTA)及ABCD2评分对短暂性脑缺血发作(TIA)患者血管特征及介入治疗的意义。方法对2010年1月—2012年1月收治的64例临床诊断TIA患者行ABCD2评分及头颈部CTA检查,分析患者头颈部血管狭窄程度、分布及其与ABCD2评分的相关性。按动脉狭窄程度将患者分为低和中高危组,中高危组中有22例患者行血管支架成形术治疗,分别于术后3、6和12个月进行随访。结果 64例患者中,头颈动脉狭窄52例(81.25%),累及动脉149段,其中颅内动脉81段(54.36%),颅外动脉68段(45.64%)。低危组患者动脉狭窄以轻、中度为主,中高危组患者以中、重度为主(χ2=10.126,P=0.018)。与血管支架成形术前的ABCD2评分(6.41±0.50)分相比,术后患者3、6和12个月评分明显降低,分别为(2.88±0.69)、(2.82±0.63)和(3.00±0.71)分,差异有统计学意义(F=86.657,P<0.05)。结论头颈部CTA联合ABCD2评分能对TIA患者狭窄血管及介入疗效进行有效评价。
Objective To discuss the application of cephalocervical CT angiography （CTA） and ABCD^2 score in evaluating arterial characteristics and interventional curative effect for patients with transient ischemic attack （TIA）. Methods During the period from Jan. 2010 to Jan. 2012, a total of 64 patients with clinically-diagnosed TIA were admitted to authors＇ hospital. ABCD^2 score evaluation and cephalocervical CTA examination were performed in all patients. The correlation of stenotic degree and distribution of the cephalocervical arteries with the ABCD^2 score was analyzed. According to the stenotic degree of the cephalocervical arteries, the patients were divided into low-risk group and mid-to-high-risk group. Twenty two patients in mid-to-high-risk group received stenting angioplasty treatment. FoUow-up was made at 3, 6 and 12 months after the treatment. Results Of 64 TIA patients, cephalocervical artery stenosis was found in 52（81.25%） A total of 149 arterial segments were involved, including intracranial segment （n = 81, 54.36%） and extracranial segment （n = 68, 45.64% ）. Patients in low-risk group mainly suffered slight or moderate arterial stenosis, while patients in mid-to-high-risk group had moderate or serious arterial stenosis （X2 = 10.126, P = 0.018）. The preoperative ABCD2 score was （6.41 ±0.50）. The ABCD2 scores determined at 3, 6 and 12 months after the treatment decreased to（2.88 ± 0.69）, （2.82 ±0.63） and（3.00 ± 0.71）, respectively. The differences were statistically significant （F = 86.657, P 〈 0.05）. Conclusion Cephalocervical CT angiography and ABCD2 score can reliably evaluate the arterial stenosis and interventional curative results in TIA patients. （J Intervent Radiol, 2014, 23： 381-384）
