1、深静脉血栓(DVT)的形成

当腿部静脉管腔内形成血块时,便出现了静脉血栓。正常情况下,血液凝固时对人体有帮助的,它能堵住伤口,防止出血过多带来的生命危险。


然而,有时这种血块的形成过程(也叫凝血)会被不恰当地激发,在不需要止血的时候于静脉内形成血块。常见的,易造成此类情况的危险因素包括:手术、肿瘤、制动、肥胖、吸烟、怀孕、家族史、药物影响等。




2、深静脉血栓的症状

大部分深静脉血栓形成具有隐匿性,并无明显症状,少数患者可发生有症状性的深静脉血栓。表现为如下症状中的一种或者多种:

1、一侧肢体突然肿胀、疼痛、触觉异常,活动后加重,抬高患肢可减轻;

2、下肢单侧(或双侧,多为左下肢)、臀部、下腹或外生殖器水肿等;

3、皮温升高 。




3、深静脉血栓的危害

深静脉血栓如果不断长大蔓延,就会像水坝一样挡住血流,导致肿胀、疼痛等症状。

较为严重的后果是导致肺栓塞,远期来讲也有可能出现血栓后综合征。

肺栓塞
脱落的血凝块可能随血流经过心脏流到肺部,阻塞肺部的血管,导致呼吸功能障碍,形成一种可能致命的疾病,称为“肺栓塞”。

肺栓塞是能致命的,因此对于它的症状有所警惕是非常重要的,这些症状主要包括:气短、胸痛、咳血和心跳加速。

研究表明,近50%的DVT可出现肺梗塞,79%肺栓塞患者合并下肢DVT。这也是为什么快速有效的治疗DVT显得那么重要,因为这样您将得到针对DVT和肺梗塞复发的有力保护。




血栓后综合征(PTS)
DVT慢性期可发生血栓后综合征(PTS),发病率为20%~50%。主要症状是下肢肿胀、疼痛(严重程度随时间的延长而变化),体征包括下肢水肿、色素沉着、湿疹、静脉曲张,严重者出现足靴区的脂性硬皮病和溃疡。

Am J Med:加压弹力袜真的能降低深静脉血栓风险吗?

研究者进行了一项荟萃分析,探究加压弹力袜对下肢深静脉血栓患者的利弊。荟萃分析共纳入了5篇关于下肢深静脉血栓形成后遗症的随机对照试验。荟萃分析结果显示,加压弹力袜对下肢深静脉血栓形成后遗症的风险HR=0.69 (95% CI, 0.47-1.02)。因为纳入的研究间具有异质性、纳入了偏倚风险高的非盲试验,所以该荟萃分析结果可信度低。排除偏倚风险高的研究后,一篇大型的低偏倚风险的随机对照试验表明(中等

Medicine: HCV感染增加深静脉血栓的风险

背景:丙型肝炎病毒(HCV)感染增加心肌梗死和卒中的风险。然而,HCV感染和深静脉血栓形成(VTE)的风险的关系尚不清楚。 方法:在纵向健康保险数据库中(LHID2000)筛选出3686名最新诊断为HCV感染的患者。随机选出14744名无HCV或HBV感染的患者作为对照组,并根据年龄,性别以及指数年与HCV感染患者进行配对。到2011年年底,计算DVT以及肺栓塞(PE)发生的密度率以及HR值。结果

JTACS:脑部损伤不会增加多发伤患者血管栓塞风险

创伤是深静脉血栓的一个主要危险因素,而脑外伤又被普遍认为会增加深静脉血栓的风险,通常需要常规预防血栓治疗。目前普遍认为多发伤患者无论是否合并脑外伤,具有较高的深静脉栓塞发生风险。但是对于该类患者目前医学界尚不清楚哪些预防方法和措施可以减少深静脉栓塞的发生。哪些合并脑外伤的多发创伤患者发生静脉血栓的机会会不会增加呢? 针对上述疑问,美国佛罗里达州的Evan J. Valle医生进行了一项回顾性研究

项研究发现去除酶因子ⅩⅢ,能降低血凝块中红细胞的数量,导致凝块的大小减少了50%。这一发现发表在Journal of Clinical Investigatio杂志上,对深静脉血栓(DVT)高风险的人有重大影响。 论文作者Alisa Wolberg博士表示:如果我们能够利用这一发现,以减少血液凝块的大小,这将意味着一个全新的方法来治疗血栓。我们认为降低ⅩⅢ因子活性可帮助一大批人,包括那些无法

Obstet Gynecol:关于围产期深静脉血栓,我们走到了哪里?

    围产期静脉血栓预防已经困扰产妇及产科医生十几年了。在绝对的意义上,年轻、健康的围产期妇女相对其他有药物史和手术史的病人来说,临床静脉血栓的发生率普遍较小。另一方面,肺栓塞是引起潜在的、也是可预防的孕产妇死亡的一个主要原因。针对这类特殊群体的一些预防措施的有效性还缺乏足够的证据,再加上一些效益方面的考虑,使这些问题仍然悬而未决。  &nb
