Abstract
Radial artery occlusion (RAO) is the commonest complication of transradial catheterization. There is no evidence-based therapy, in the frame of a randomized control study, for the treatment of RAO. The purpose of the LOW-RAO study is to question the hypothesis if low-molecular-weight heparin is effective in the treatment of RAO after transradial coronary catheterization (both angiography and percutaneous coronary intervention). It is a prospective, openlabel, randomized controlled trial that will randomize 60 patients with RAO, irrespective of symptoms, into two groups, one receiving anticoagulation with low-molecular-weight heparin and the other receiving no treatment. The primary endpoint is improvement in radial artery patency rate at 4weeks after the procedure. Clinical trial registration number: NCT04196309 (ClinicalTrials.gov).
