Summary
The Woven EndoBridge (WEB) device shows acceptable 5-year occlusion rates for intracranial aneurysms. Recanalization is unlikely after two years, suggesting promising long-term outcomes for this minimally invasive treatment.
Area of Science:
- Neuroendovascular
- Neurosurgery
- Radiology
Background:
- Intracranial aneurysms (IAs) pose significant risks.
- Endovascular treatments are evolving for IA management.
- The Woven EndoBridge (WEB) device is a notable option.
Purpose of the Study:
- To evaluate the 5-year radiological outcomes of IAs treated with the WEB device.
- To assess the long-term efficacy and safety of WEB embolization.
Main Methods:
- Multi-center retrospective study.
- Inclusion of patients treated with WEB from January 2013 to December 2016.
- Assessment of aneurysm occlusion using a 3-grade scale at 5-year follow-up.
Main Results:
- 83.7% of treated IAs achieved adequate occlusion at 5 years.
- Complete occlusion was observed in 47.3% of cases.
- Recanalization occurred in 16.3% of IAs, with no rebleeding events reported.
Conclusions:
- The WEB device demonstrates acceptable long-term occlusion rates for intracranial aneurysms.
- Recanalization is infrequent after the initial two years post-treatment.
- Further large-scale studies are warranted to confirm these findings.

02:20Longitudinal Research
12.1K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

01:22Fatigue Strength of Concrete
248
Fatigue, in the context of materials science and engineering, refers to the weakening or failure of a material caused by repeatedly applied loads, even if these loads are below the strength limit of the material. Fatigue strength in concrete is a critical property that influences its durability and longevity. Concrete can fail in two ways due to fatigue. Static fatigue or creep rupture occurs under a constant load or one that increases slowly. The other failure mode is due to cyclical or...

01:15Brick Durability, Strength, and Appearance
308
Brick durability, strength, and appearance are crucial factors in construction, influencing the choice of bricks for specific applications. The process of freeze-thaw, for instance, significantly affects brick durability. This phenomenon occurs when water absorbed by a brick expands as it freezes, potentially causing damage when it melts and refreezes. Bricks are graded for durability: SW-grade bricks are the most durable, offering high strength and low water absorption, followed by MW-grade...

01:23Abrasion Resistance of Concrete
179
Abrasion resistance is an essential characteristic of concrete that determines its durability and longevity under various wear conditions. Concrete surfaces are vulnerable to different types of abrasion. For instance, surfaces may wear down due to the constant movement of vehicles or be eroded by solids carried in water, as seen in concrete canal linings. Specific tests are conducted to measure the abrasion resistance of concrete.

01:22Toughness and Hardness of Aggregate
317
Toughness and hardness are critical properties of aggregate materials used in concrete, particularly on pavement surfaces and industrial flooring subjected to heavy loads. Toughness is defined as the aggregate's resistance to failure by impact and is measured by the aggregate impact value (AIV). For this, the aggregate impact value test is performed, wherein the impact is delivered by a standard hammer, which falls freely under its own weight onto the aggregates. The aggregates fragment in...

55.6K
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.
