Unsymmetric Loading of Thin-Walled Members

Unsymmetric Loading of Thin-Walled Members

Thin-walled members with non-symmetrical cross-sections are vital to engineering structures, offering material efficiency and structural integrity. However, unsymmetrical loading on these members leads to complex stress distributions, resulting in simultaneous bending and twisting can cause deformation or structural failure. The interaction between bending and twisting requires detailed analysis to ensure structural resilience.
The concept of the shear center is crucial in countering the...

Background:

Transarterial embolization is a critical intervention for acute bleeding.
Novel embolic agents are needed to improve procedural outcomes and safety.
Obsidio conformable embolic (OCE) is a shear-thinning agent designed for embolization.

Purpose of the Study:

To evaluate the technical success, effectiveness, and safety of Obsidio conformable embolic (OCE) for acute bleeding management.
To assess the performance of OCE in various bleeding indications.
To determine the short-term safety profile of OCE in transarterial embolization procedures.

Main Methods:

Single-center retrospective study of 11 patients undergoing 11 embolization procedures.
Embolization performed using Obsidio conformable embolic (OCE) in 16 arteries.
Technical success defined as complete stasis of antegrade flow within the target vessel.
Effectiveness defined as cessation of bleeding; safety assessed via adverse events and off-target embolization.

Main Results:

100% technical success rate achieved in all embolization procedures.
OCE demonstrated effectiveness in managing diverse bleeding sources, including tumor bleeding, hematuria, and duodenal bleeding.
No adverse events or off-target embolization were reported, indicating a favorable safety profile.

Conclusions:

Obsidio conformable embolic (OCE) is a technically successful and effective agent for transarterial embolization in acute bleeding management.
OCE exhibits a promising short-term safety profile, with no reported adverse events or off-target embolization.
OCE represents a viable option for embolization interventions, offering both efficacy and safety.
