Radial vs femoral access for brain artery imaging
Part of Brain & nervous system clinical trials.
This trial compares two ways doctors reach the blood vessels to do diagnostic brain angiography: through the wrist artery (radial) or the groin artery (femoral). It may help show which access route is safer or easier for people needing this brain blood vessel imaging.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re between 18 and 80 years old.
- You are scheduled for diagnostic brain angiography (a test of brain blood vessels).
- You can likely be done through both the wrist and groin, with a wrist artery at least 2 mm wide on an ultrasound.
- Your disability score (mRS) is 0 to 2.
- You can sign a written consent form.
- No major blood flow blockages in key arteries that could prevent passing the instrument.

This trial compares two ways to perform a brain angiogram: one through the wrist (radial artery) and the other through the groin (femoral artery). It wants to see which is safer and works better.
This trial tests whether a new wrist access point (the distal radial artery) along with specific drug treatments (CAG and PCI) is safe and effective for people with small blood vessels in the heart. It aims to offer an alternative that may reduce bleeding or damage risks.
This study compares two different ways doctors can perform brain vessel imaging (cerebral angiography): through the wrist (transradial) versus through the groin (transfemoral). Researchers want to see which approach is safer and more effective for patients who need this imaging.
This trial tests if a robot can help perform a brain artery scan through the wrist as safely and effectively as the standard manual method. It might be an option if you need a detailed look at blood vessels in your brain.
This study compares two ways doctors can reach the heart during a catheter procedure: through the wrist (radial) or the groin (femoral). It aims to reduce bleeding and access-site complications, especially when patients may need a balloon/stent (PCI).
This trial tests a new imaging system and tiny catheter that lets doctors see inside brain blood vessels more clearly during a planned angiogram. It may help people who need follow-up imaging after previous treatment or a diagnostic look at their vessels.
