概括

机械血栓切除术 (MT) 过程中的下游阻塞 (DOC) 对大血管阻塞 (LVO) 影响36.1%的患者,但不会影响最终结果. 额外的内血管治疗可以有效地管理DOC,强调需要进行完整的再输血.

科学领域:

神经学神经学
干预性神经辐射学
血管外科血管外科

背景情况:

下游阻塞 (DOC) 是机械血栓切除术 (MT) 的常见并发症,用于急性大血管阻塞 (LVO).
人们对DOC的患病率,预测因素和临床影响仍然不完全了解.
了解DOC对于优化MT程序和患者结果至关重要.

研究的目的:

确定DOC的患病率和独立预测因子,在为内LVO接受MT的患者中.
分析DOC和没有DOC的患者的内血管轨迹和临床结果.
评估后续的重新道化尝试在管理DOC.的有效性.

主要方法:

对703名接受MT治疗的急性内LVO患者 (2010-2021) 的回顾性分析.
血管图识别DOC作为一个新的阻塞远距离主部位后的recanalization.
预测分析的多变量逻辑回归;DOC和非DOC组之间的结果比较.

主要成果:

DOC发生在36.1%的患者中,心房动和近心闭塞作为独立预测因素.
患有DOC的患者表现出相似的最终成功再通道化 (92.5%) 和功能独立 (40.2%) 率.
对DOC进行额外的内血管治疗,在76.7%的病例中改善了再输液,根据位置而变化的功能益处.

结论:

尽管程序复杂,但DOC并不会显著影响最终的再道化或功能结果.
通过进一步的内血管干预,可以实现DOC的有效管理.
在MT中,即使在DOC的存在下,达到足够的最终再注射仍然是最重要的.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
