Summary
Balloon-assisted WEB deployment is a safe and effective method for treating intracranial aneurysms. This technique enhances the utility of the Woven EndoBridge (WEB) device for various aneurysm types and locations.
Area of Science:
- Neurosurgery
- Interventional Neuroradiology
- Vascular Neurology
Background:
- Balloon-assisted deployment is a recognized technique for intracranial aneurysm coil embolization.
- The Woven EndoBridge (WEB) device is used for aneurysm treatment.
- Balloon-assisted deployment may aid in WEB device delivery.
Purpose of the Study:
- To assess the safety, efficacy, and feasibility of balloon-assisted WEB deployment.
- To evaluate this technique in both ruptured and unruptured intracranial aneurysms.
- To analyze its use in typical and atypical aneurysm locations.
Main Methods:
- Retrospective review of patients treated with balloon-assisted WEB deployment (BAWD).
- Data collected from a prospectively maintained database across two neurointerventional centers.
- Analysis included patient demographics, aneurysm characteristics, procedural details, and clinical/imaging outcomes.
Main Results:
- 33 aneurysms (64.3% anterior circulation) in 23 patients (median age 58) were treated.
- 15 (45.5%) aneurysms were ruptured; 12 (36.4%) were in atypical locations.
- Procedure-related mortality was 3.0%; no permanent morbidity. Mid-term occlusion rates were 85.2% complete and 92% adequate.
Conclusions:
- Balloon-assisted WEB deployment is a safe and effective technique.
- This method may expand the applicability of the WEB device.
- Further prospective studies on BAWD are recommended.

01:09Bending of Material: Problem Solving
In this lesson, determine the ratio of the maximum bending moments applied to two metal pipes, given that both pipes can withstand a maximum stress of 100 MPa. Both pipes have an outer radius of 1.8 cm. Pipe A has an inner radius of 1.5 cm, and Pipe B has an inner radius of 1 cm. The ratio of the maximum bending moment applied to two metallic pipes, each with a different inner and outer radius, is determined by considering their dimensions. The inner radius of the first pipe is 1.5 cm, and for...
01:17Design Example: Calculating Safe Diameter for Wind-Exposed Disc
Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...
