概括

患者患有阻塞性黄,通常与恶性瘤有关,通常导致正常或高凝血状态,而不是低凝血. 这项研究挑战了在这种情况下血液凝固受损的传统观点.

科学领域:

肝病学肝病学是一种肝病学.
凝血科学凝血科学
在瘤学瘤学.

背景情况:

阻塞性黄通常被认为是由于维生素K吸收不良而导致低凝血.
然而,恶性瘤和肝功能障碍可以调解高凝血能力.
胆道阻塞对凝血的真正影响仍然不清楚.

研究的目的:

为了确定胆道阻塞患者的凝血状态.
使用旋转性血栓形成显微镜 (ROTEM) 来评估凝血概况.

主要方法:

澳大利亚一家医院的前性队列研究.
包括总 bilirubin >150 umol/L 和成像证实胆道阻塞的患者.
使用ROTEM评估的凝血.

主要成果:

研究了20名患有高胆红素水平的患者 (平均年龄74.5岁).
17名患者患有恶性胆道阻塞.
ROTEM显示出正常或减少的凝块形成时间和正常或增加的凝块牢固度,表明正常或高凝结能力.

结论:

患有阻塞性黄的患者,特别是由于恶性瘤,是正常或高凝血的.
在阻塞性黄中存在低凝血性的既定信念需要重新评估.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
