概括
术前栓塞并没有改善经过微手术的脑动脉静脉形形 (AVM) 的结果. 较大的AVM更有可能被栓塞,但这种选择没有显示出功能或血管学结果的明显好处.
科学领域:
- 神经外科 神经外科
- 干预性神经放射学 干预性神经放射学
- 血管神经学 血管神经学
背景情况:
- 作为对脑动脉静脉形形 (AVM) 微手术切除的辅助,手术前栓塞的疗效尚未得到充分证实.
- 这项研究调查了临床和血管学结果,比较了用于AVMs的手术前栓塞和没有手术前栓塞的微手术.
- 还检查了影响选择手术前栓塞的因素.
研究的目的:
- 评估脑动脉静脉形形 (AVM) 的微手术切除与或没有手术前栓塞的临床和血管学结果.
- 确定与选择患者进行手术前栓塞相关的因素.
- 为了比较微手术切除单独的安全性和有效性与随后进行微手术的栓塞.
主要方法:
- 在2015年7月至2025年6月期间,对104名接受AVM微手术切除的患者进行了回顾性观察队列研究.
- 倾向得分方法 (1: 3匹配,治疗权重的逆概率) 用于调整组之间的基线差异.
- 主要结局是90天治疗相关的发病率 (修改的兰金级增加≥1);次要结局包括功能依赖,出血,心脏病发作,消灭和死亡率.
主要成果:
- 在104名患者中,91人仅进行了微手术,13人进行了手术前栓塞,随后进行了微手术.
- 栓塞的AVM较大 (平均3.8比2.5厘米),供应更深,Spetzler-Martin等级更高.
- 经过调整后,在90天的发病率,功能依赖性或死亡率方面,两组之间没有发现显著差异. 动脉动脉瘤大小 (≥3厘米) 与栓塞选择有关,但没有改善结果.
结论:
- 带有或没有手术前栓塞的微手术切除在这个单中心研究中产生了类似的短期功能和血管学结果,尽管估计不准确.
- 动脉动脉瘤的大小是栓塞选择的主要因素,但这并没有转化为可证明的结果优势.
- 需要进行前性多中心研究,以确定血栓塞是否在选定的AVM患者中提供增量益处.

Observational Studies

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Pulmonary Embolism I: Introduction
828
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Naturalistic Observations
17.6K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Observational Learning
1.0K
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Actor-Observer Effect
421
The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in...
