急性脑出血、脑梗塞的血栓弹力图(TEG)分析

Study of Thromboelastogram of Patients with the Acute Cerebral Hemorrhage and Cerebral Infarction

本文分析了62例急性脑出血和脑栓塞患者的血栓弹力图(TEG)改变。显示5种不同的图象:本组未见 K 值和 Y 值的明显缩短,而大多数病例有α角的增大和 Ma 值的增宽.这些改变提示这一年龄组的患者因动脉内纤维蛋白形成增加而至血管内皮损.TEG 图象显示纤溶亢进的病例,没有观察到规律性的改变。因此考虑是否在正常凝血之后发生纤溶亢进而引起出血,而一般凝血机制检查未能显示常异。本组探索出一个新的纤溶图象测定指标,并命名为δ角.测定35例正常人 TEG 图象δ角在0～5度之间,纤溶亢进时δ角相应增大。

Thromboelastograms(TEG)of 62 patients,with the acute cerebral hemorrhage and cerebral infarction were analysed.The TEG in these patients demonstated five distinct models. No obvious shortenings of values K and Y were observed in one's group but a angle was enlarged with a widened Ma value in most patients.It was suggested that these variatiuns may be related to the impairment of the intima of artery in the aged,which increased formation of fibrin. In cases where TEG displaed accelerating fibrinolysis no variation was detected. Accelerating fibrinolysis could be more distinct enpressed through pic- tures then through figures.So we proposed to use δ angle as a digital pa- rameter to manifest elevated fibrolysis,the angle between two parallel lines across dismal two endpoint of Ma and vertical to it and two curve of TEG.Normal value of δ angle is 0°to 5°
