- 静脉外流 (VO) 是急性缺血性中风 (AIS) 患者的关键预后成像生物标志物.
- 在多相CT-血管学 (mCTA) 上精确评估VO对于选择患者接受内血管治疗 (EVT) 是必不可少的.
- 在mCTA上对VO的最佳评分方法需要进一步调查.
研究的目的:
- 评估和比较mCTA上的不同静脉外流 (VO) 评分方法.
- 确定最有效的VO得分,用于预测接受EVT的AIS患者的功能结果.
- 确定成功EVT的VO分数的独立预测值.
主要方法:
- 在24小时内对连续AIS患者进行EVT进行大血管封闭的回顾性分析.
- 评估多个VO得分:精确,COVES,综合静脉外流 (CVO) 和内脑静脉 (ICV) 不对称.
- 使用接收器运行特征 (ROC) 曲线和多变量逻辑回归来预测良好的功能结果的统计分析 (修改的兰金尺度0-2在3个月).
主要成果:
- 综合静脉外流 (CVO) 评分是良好功能结果的唯一独立预测指标 (OR=2.51,p=0.001).
- CVO评分表现出良好的区分性表现,AUC为0.75和最佳切线≥4.4.
- 良好的CVO概况与更好的附带循环,更高的再通道率和较低的症状性内出血率相关.
结论:
- 从mCTA获得的CVO得分是接受EVT的AIS患者功能结果的强大和独立预测器.
- 与其他评估的VO分数相比,CVO分数提供了更好的区分性能.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
280
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...

Venous Return
11.6K
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...

Venous Thrombosis IV: Nursing Management
190
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

Assessment of the Cardiovascular System III: Palpation
985
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Venous Thrombosis III: Interprofessional Care
271
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
334
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...
