概括
延长的静脉过渡 (PVT) 与大核心急性缺血性中风 (AIS) 与大血管封闭 (LVO) 的不良结果有关. 这一发现表明PVT可能有助于预测中风治疗后患者的康复.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 心血管研究研究心血管研究
背景情况:
- 大核心急性缺血性中风 (AIS) 由于大血管封闭 (LVO) 往往导致严重的残疾,即使在机械血栓切除术 (MT) 后.
- 延长静脉通道 (PVT),在CT输液扫描中确定,表明静脉排水受损,是潜在的预后标志物.
- 大核心AIS-LVO患者PVT的预后价值需要进一步澄清.
研究的目的:
- 为了研究延长静脉通道 (PVT) 与大核心AIS-LVO患者的功能结果之间的关联.
- 测试PVT是该患者队列中不利结果的独立预测因素的假设.
主要方法:
- 在2016年9月至2024年9月期间,对100名患有AIS-LVO和大缺血核心体积 (ASPECTS<6或rCBF<30%体积≥50毫升) 的患者进行了回顾性队列研究.
- 在治疗前CT输液时,PVT被评估使用时间至最大 (Tmax) 地图,定义为Tmax ≥10秒在上部斜或扭头.
- 主要结局是90天后不良的功能恢复 (修改的兰金级得分4-6).
主要成果:
- 41%的患者表现出PVT. 在PVT患者中,不利的功能结局明显更常见 (59%对37%,p=0.036).
- 多变量分析显示PVT是不利结果的独立预测因素 (调整后OR为4.07,p=0.03),即使控制半阴影和核心体积.
- 其他独立预测因素包括年龄较大,入院率较高的NIHSS和较大的低相对脑血流量 (rCBF<30%).
结论:
- 延长的静脉通道 (PVT) 独立地与患有大核心AIS-LVO.患者的不良功能结果有关.
- 在这种高风险中风群体中,PVT可以作为指导治疗决策的有价值的预后标志物.
- 需要进一步的前性研究来验证这些发现及其临床实用性.

Venous Thrombosis I: Introduction
361
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...

Venous Thrombosis III: Interprofessional Care
278
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 IV: Nursing Management
192
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,...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
286
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
11.7K
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...

Varicose Veins I: Introduction
147
Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...
