摘要
目的探讨脑动静脉间脉搏波传导时间(cerebral arerio-venous pulse wave time,CAV-PWT)与腔隙性脑梗死(lacunar infarction,LI)的相关性。方法按照病例对照研究方法,采集40例LI患者和20例对照组人口学资料和相关危险因素。采用经颅多普勒(transcranial dopple ultransonograp,TCD)仪同步监测颈内动脉终末段(terminal internal carotid artery,TICA)与基底静脉(Rosenthal’s veins;venae basalis,BVR)的脉搏波,计算CAV-PWT,比较2组间CAV-PWT的差异,以及分析CAV-PWT与人口学资料和危险因素间的关系。结果病例组患者的CAV-PWT(73.53±15.81 ms)与对照组(106.02±28.06 ms)比较明显缩短(P<0.05)。多元回归分析显示:CAV-PWT与体重指数X1和年龄X3负相关(rs=-0.697与-0.3258,P<0.05),与头围、性别、血糖、血脂和血压无明显相关性。回归方程Y=210.168-4.661X1-0.459X3。Logistic回归分析显示:年龄X3、PWTX4和高血压X9是LI的危险因素(P<0.05),其回归方程logit P=-8.034-2.178X1+5.066X3+3.775X4+4.865X9(掊2=20.181,P<0.01)。结论LI患者CAV-PWT明显缩短,可能与脑小动脉硬化有关。
Objective To investigate the relationship between cerebral arerio-venous pulse wave time （CAV-PWT） and lacunar infarction. Methods Forty patients with lacunar infarction and 20 sex-and-age-matched control subjects were studied. The pulse wave of terminal intemal carotid artery and basal vein were simultaneously monitored by TCD and the CAV-PWTs were then calculated. The difference in CAV-PWT between patients and controls and the relationships of CAV-PWT with demographic data and risk factors were analyzed. Results The CAV-PWT was signif- icantly shorten in patient group than in control group （73.53 ± 15.81 ms vs 106.02 ±8.06 ms） （P 〈 0.05）. Multi- ple linear regression revealed that CAV-PWTs were negatively correlated with body mass index and age （ra=-0.697 and -0.3258, P 〈 0.05）, but not with head circumference, gender, blood sugar, blood fat or blood pressure. The regression equation was： Y = 208.928-4.661X1-0.459X3 （F = 22.358, P 〈 0.001） Logistic regression analysis showed that age, PWT and high blood pressure were risk factors for lacunar infarction（P 〈 0.05）. The regression equation was logit P =-8.034 ＋ 5.066X3 ＋ 3.775X4 ＋ 4.865X9（X^2 = 20.181, P 〈 0.01）. Conclusions The CAV-PWT is significantly shorten in lacunar infarction, which may be associated with cerebral arteriolosclerosis.
