Arm or groin? study seeks safer route for leg artery treatment
NCT ID NCT07694050
First seen Jul 09, 2026 · Last updated Jul 14, 2026 · Updated 3 times
Summary
This study compares two ways to access blocked leg arteries during a procedure to restore blood flow: through the arm (brachial artery) or the groin (femoral artery). The goal is to see which approach leads to fewer complications, such as bleeding or artery damage. Participants are aged 60 or older with blocked leg arteries needing treatment. Doctors will track complications within 72 hours after the procedure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If one access site proves safer, it could become the preferred method for these procedures, reducing complications.
- What could go wrong
- This is an observational comparison, not a test of a new treatment. Results may not apply to all patients or settings.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion criteria: * arterial diameter at the access site of at least 3 mm, indications for endovascular intervention on the lower extremity arteries, * age of 60 years or more, and patient consent to participate in the study. Exclusion criteria: * inability to perform an access due to stenotic lesions of the above-mentioned arteries (common femoral artery, iliac arteries, axillary artery, subclavian artery, and brachiocephalic trunk); * height exceeding 180 cm; * presence of concomitant pathology that limits patient survival; coagulation system pathology (hemophilia, thrombocytopathies, etc.) * previous arterial access catheterizations.
