Summary
Advancements in stent technology offer new treatments for neurovascular conditions like aneurysms and ischemic diseases. Widespread use for carotid stenosis awaits further clinical trial results.
Area of Science:
- Neurology
- Interventional Neuroradiology
- Biomedical Engineering
Background:
- Stent technology has rapidly advanced since 2008, leading to increased research and clinical applications.
- Stents are utilized for complex aneurysm treatments and revascularization in neurovascular ischemic conditions.
Purpose of the Study:
- To review the advancements in stent technology for neurovascular applications.
- To highlight the evolving role of interventional neuroradiology in treating cerebrovascular diseases.
Main Methods:
- Review of case reports, case series, and randomized trials concerning stent technology in neurovascular treatment.
- Discussion of different stent designs (semiopen cell vs. closed-cell) and their applications.
Main Results:
- Self-expanding nitinol stents are used for intracranial occlusive disease.
- Retrievable closed-cell stents facilitate aneurysm treatment due to easier microcatheter delivery in tortuous vessels.
- Clinical trial results are pending for routine carotid stenosis treatment.
Conclusions:
- Stent technology has significantly evolved, offering versatile neurovascular treatment options.
- Interventional neuroradiology plays an expanding role in managing acute ischemic stroke.
- Further multicenter trials are necessary to establish routine use of stents for carotid stenosis.

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
