摘　　要：目的探讨血栓弹力图在后循环缺血致眩晕诊断中的应用价值。方法选取2013年5—12月在解放军309医院就诊的90例年龄60岁及以上的眩晕患者为研究对象,分为良性位置性眩晕组(A组)30例和后循环缺血致眩晕组(B组)60例。两组患者采用血栓弹力图进行检测。结果 A组患者的反应时间(R)、凝固时间(k)、最大凝固时间(m)分别为(6.56±0.17)min、(1.75±0.08)min、(38.71±1.31)min,均高于B组患者的(4.55±0.55)min、(1.51±0.13)min、(31.70±1.17)min,差异有统计学意义(P<0.05)。A组患者的凝固角(α)、血栓最大幅度(mα)、血栓最大弹力度(mε)分别为(65.66±1.16)°、(63.58±0.94)mm、(92.51±1.44)mm,均低于B组患者的(68.59±1.60)°、(67.71±1.36)mm、(135.74±1.25)mm,差异有统计学意义(P<0.05)。结论后循环缺血致眩晕多表现出血液高凝状态,血栓弹力图可辅助鉴别眩晕类型。Objective To investigate the application value of thrombelastography in the diagnosis of Chinese posterior circulation ischemia vertigo. Methods We enrolled 90 patients with vertigo who were aged over 60 and were hospitalized in the 309th Hospital of Chinese People＆#39;s Liberation Army from May to December in 2013. And then we assigned 30 subjects into the benign positional vertigo group（group A）and 60 subjects into the posterior circulation ischemia vertigo group（group B）. The two groups were examined using thrombelastography. Results Reaction time（ R）,clotting time（ k）,maximum clotting time （m）were respectively（6. 56 ± 0. 17）min,（1. 75 ± 0. 08）min and（38. 71 ± 1. 31）min for group A and respectively （4. 55 ± 0. 55）min,（1. 51 ± 0. 13）min and（31. 70 ± 1. 17）min for group B,with group A higher（P﹤0. 05）than group B in all the three indicators. Clotting angle（α）,maximum thrombus amplitude（ mα）and maximum thrombosis resilience （mε）were respectively（65. 66 ± 1. 16）o,（63. 58 ± 0. 94）mm and（92. 51 ± 1. 44）mm for group A and respectively （68. 59 ± 1. 60）o,（67. 71 ± 1. 36）mm and（135. 74 ± 1. 25）mm for group B,with group A lower（P﹤0. 05）than group B in all the three indicators. Conclusion Posterior circulation ischemia vertigo is mostly manifested as a hypercoagulable state,and thrombelastography can assist to identify the types of vertigo.
