What is a key feature of the stents used in neuro angiography?

In neuroangiography, stents play a critical role in maintaining vascular access and providing structural support to arteries, especially in the context of complex cerebral vasculature. A key feature of the stents used in this field is their ability to conform to the walls of the blood vessels. This conformability is essential because the brain's arteries can have various diameters, curvatures, and shapes. A stent that can adapt to these diverse anatomical features helps ensure that blood flow is maintained while minimizing the risk of complications, such as stent migration or inadequate apposition to the vessel wall.

The design of conformable stents allows them to improve patient outcomes by enhancing the effectiveness of procedures like stent-assisted coiling of aneurysms or treating arterial stenosis. This flexibility also aids in reducing trauma to the vessel walls and minimizing the risk of thrombosis associated with poor stent positioning.

In comparison, rigid materials, while providing strength, may not adapt well to the anatomy they are deployed in, potentially leading to complications. Not all stents are covered since covered stents particularly address issues like leaks or perforations, which are not universally applicable in all cases. Furthermore, stents are not solely employed in situations of extrinsic compression; they
