概括
延长的静脉过路 (PVT) 与基础动脉封闭 (BAO) 中风治疗后的更糟糕结果有关. 年轻的患者和NIHSS得分较低的患者在内血管血栓切除术 (EVT) 后表现出更好的功能恢复.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 脑卒中医学 脑卒中医学
背景情况:
- 延长静脉通行 (PVT) 是Tmax地图上静脉外流 (VO) 的成像标志物.
- 存在PVT (PVT+) 与前部循环急性缺血性中风 (AIS-LVO) 的不良结果相关,该中风用内血管血栓切除术 (EVT) 治疗.
- 需要调查PVT与后部循环中风的结果之间的关联,特别是基底动脉封闭 (BAO).
研究的目的:
- 在急性BAO患者中,在EVT后90天确定PVT和功能结果之间的关联.
- 为了比较PVT和没有PVT的BAO患者的特征和结果.
主要方法:
- 追溯研究包括来自九个学术医疗中心的97名急性BAO患者.
- 血栓切除前CT或MR输液成像用于评估PVT.
- PVT被定义为Tmax ≥10秒延迟后部循环静脉鼻;90天的功能结果被评估使用修改的兰金尺度 (mRS).
主要成果:
- 60%的BAO患者有PVT+;PVT-患者年轻,并且在90天 (44%对22%) 后更有可能具有优秀的功能结果 (mRS 0-1).
- 呈现较低的NIHSS显着与优秀的功能结果相关 (OR:0.89;95%CI:0.82-0.96).
- 年龄和PVT之间的显著相互作用表明,PVT+的老年患者的治疗结果更差.
结论:
- 在接受EVT治疗的急性BAO患者中,PVT与更糟糕的功能结果有关,特别是在老年人中.
- 在演示时较低的NIHSS分数预示着卓越的功能恢复.

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...

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 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...

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,...
