经颅多普勒监测缺血性卒中患者脑动脉微栓子   总被引:1,自引:0,他引:1  
目的 了解缺血性卒中患者微栓子的发生率及其可能发病机制。方法 采用德国EMETC 4 0 4 0型经颅多普勒 (TCD)检测仪 ,用soundtrack 2 .4版本的软件对 61例缺血性卒中患者双侧大脑中动脉 (MCA)进行微栓子监测。监测时间不少于 3 0min ,监测前常规行颈动脉B超检查。结果  6例发现了微栓子 (占 9.83 % ) ,其中 3例为心脏机械瓣膜修复术后患者 ( 1例合并脑栓塞 ,另 2例神经功能正常 ) ,另 3例为非心源性脑梗死患者(占 5 8例非心源性脑梗死患者中 5 .17% )。 3例颅外颈动脉狭窄的患者中 1例微栓子阳性。在非心源性脑梗死患者中 ,仅于患侧MCA处监测到微栓子 ,而在心脏人工瓣膜修复术后患者中 ,双侧MCA均可监测到微栓子。结论 非心源性脑梗死急性期微栓子阳性率低 ,可能与颅外颈动脉狭窄程度有关。  相似文献

目的:机械心脏瓣膜置换术后远期INR与并发症的关系,最佳抗凝强度范围及意义。方法:对机械心脏瓣膜置换术后出院半年以上的患者在门诊检查四项凝血指标(PT,PTR,INR,Fbg,APTT)224例次,按照INR结果不同分为三组:I组INR<1.5,II组INR1.5~2.5,III组INR>2.5。结果:I组26例/次,华发林服用量3.55±1.03mg,INR1.39±0.10,出现脑栓4例/次,并发症15.3%;II组176例/次,华发林服用量3.44±1.02mg,INR2.13±0.11,出现鼻出血、血尿5例/次,并发症2.8%;III组22例/次,华发林服用量2.96±1.07,INR2.91±0.62,出现鼻出血、皮下出血4例/次,并发症18%。结论:II组的例/次占总数的77.8%,INR在1.5~2.5之间并发症最低,说明INR在1.5~2.5之间是安全可靠的,是本地区最佳抗凝强度范围。机械心脏瓣膜置换术后抗凝强度是动态的,术后远期更应高度关注抗凝状态。  相似文献

目的 明确动力型微泡清除器 (DBT)在冠脉搭桥患者体外循环 (CPB)全过程中减少动脉灌注管道和大脑中动脉内微气泡的效果及其对血细胞和凝血机能的影响。方法  2 0例患者随机分组 ,DBT组在动脉滤器与主动脉插管之间接入DBT。检测DBT前、后的动脉灌注管内和对照组相应位置的微气泡量和患者双侧大脑中动脉内微栓信号 (MES)量。术前、CPB停止和术后 6h分别测定血浆游离血红蛋白 (PFH)、乳酸脱氢酶 (LDH)、血小板计数、纤维蛋白原、凝血因子Ⅱ活性、抗凝血酶Ⅲ(ATⅢ )活性。结果 DBT组动脉灌注管内不同直径微气栓的清除率分别为 6 8%~ 74 % (10~ 12 0 μm) ,79%~ 81% (2 0~ 12 0 μm)和 88%~ 96 % (40~ 12 0 μm )。整个CPB期间大脑中动脉内MES总值 ,DBT组 (178± 12 2 )比对照组 (197± 137)有减少的趋势 ,但差异无显著意义。血细胞破坏和凝血机能各指标在两组间差异无显著意义。结论 DBT能高效清除体外循环动脉灌注管内微气泡并且不加重血细胞的破坏或凝血抗凝机制的紊乱。要最大程度消除入脑气体微栓须采取综合临床措施 ,而DBT是有效手段之一。  相似文献

Evidence obtained from randomized controlled trials (RCTs) has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine (TCM) and results have shown that there is an urgent need for higher quality RCTs on TCM.  相似文献

Ankylosing spondylitis is a chronic and progressive disorder with inflammation mainly involving the central axis joints. It mainly affects the cervical spine and the lumbosacral area, with the pathogenesis closely related to the kidney and the Governor Vessel (GV). TCM holds that the syndrome is deficiency in origin and excess in superficiality, which is due to insufficiency of the kidney, deficiency of GV, and blocking of the channels with the invasion of exogenous evil, leading to poor circulation of qi and blood and malnutrition of the bones, muscles and joints. The TCM method of tonifying the kidney and strengthening GV to regulate circulation of qi and blood and check the arthralgia pain should be adopted, with the Kidney-Tonifying and GV Strengthening Decoction (益肾强督汤) prescribed.  相似文献
