概括
静脉外流 (VO) 概况,特别是VO (PTV) 峰值时间,与急性缺血性中风 (AIS) 患者的组织水平附带体 (TLC) 有关. ≤13s的PTV有效地预测了有利的TLC,有助于治疗决策.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 组织层面的附带体 (TLC) 表示缺血性脑组织中的动脉血流,与急性缺血性中风 (AIS) 的临床结果相关.
- 静脉外流 (VO) 形状和TLC之间的关系,独立于动脉附带状态,仍然未得到充分研究.
研究的目的:
- 在前部循环AIS和大血管封闭 (LVO) 的患者中,研究从计算机断层输液 (CTP) 和组织水平附带物 (TLC) 获得的静脉外流 (VO) 参数之间的关联.
- 通过计算机断层扫描血管学 (CTA) 评估的动脉附带状况,以确定VO档案是否预测有利的TLC,无论动脉附带状况如何.
主要方法:
- 在2021年1月至2023年8月期间评估的221名经过血栓切除术的LVO AIS患者的回顾性分析.
- 使用CTP数据来推导VO参数:VO的峰值时间 (PTV) 和总VO时间 (TVT).
- 组织水平的附带资产 (TLC) 通过低 perfusion 强度比 (HIR ≤0.4) 量化,后勤和ROC分析评估了TLC的VO参数的关联和预测值.
主要成果:
- 与不良TLC (16.5s) 患者相比,具有有利TLC的患者表现出较短的PTV (12s).
- 较短的PTV与有利的TLC (OR,0.811;P=0.002) 有着显著的关联,无论动脉附带状况如何.
- 接收器运行特征 (ROC) 分析发现PTV值≤13s用于预测有利的TLC (AUC=0.754),组合预测因素实现AUC为0.894.
结论:
- 大脑VO概况,特别是PTV,与LVO的AIS患者的TLC显著相关,无论动脉附带状况如何.
- ≤13s的PTV作为有利TLC的有价值预测指标,有助于在AIS中评估大脑输液.

The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

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...
