- 血管神经学 血管神经学
- 紧急医疗 紧急医疗
背景情况:
- 静脉血栓溶解在发作后4.5至24小时内对后部循环缺血性中风的疗效和安全性仍未得到充分研究.
- 后部循环中风经常出现复杂的症状,需要进一步研究最佳治疗窗口.
研究的目的:
- 评估在4.5至24小时的延长时间窗口内,在患有后部循环缺血性中风的患者中阿尔泰的有效性和安全性.
- 为了在这个患者队列中比较阿尔特普拉斯和标准医疗治疗之间的功能独立性和死亡率.
主要方法:
- 在中国的一项随机试验中,234名患有后部循环中风的患者被分配到阿尔特或标准医学治疗中.
- 患者在症状出现后4.5至24小时接受治疗,不包括患有广泛的早期低血压或计划性血栓切除的患者.
- 主要结局是90天后的功能独立,使用修改的兰金度量表进行评估;关键的安全结局包括症状性内出血和死亡.
主要成果:
- 90天后的功能独立性在阿尔特雷普拉斯组 (89.6%) 与标准治疗组 (72.6%) 相比显著更高 (调整后风险比,1.16;P=0.01).
- 在36小时内出现症状性内出血的发病率很低,在各组之间可比 (1.7%对比0.9%).
- 在90天后的死亡率在阿尔特酶组 (5.2%) 略低于标准治疗组 (8.5%).
结论:

Clot Retraction and Fibrinolysis
3.1K
After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.

Formation of the Platelet Plug

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
