Adolescent radial arteries ‘wide enough for intervention’

Many children over 12 years have radial arteries large enough for transradial interventions, researchers report.
Canadian doctors sought to establish a reference range of radial artery diameters in children across different age groups to support clinical decision-making.
Transradial access affords several advantages over the traditional transfemoral route, including lower risks of bleeding and vascular complications, patient preference and cost benefits, the authors said.
But the approach had not been investigated extensively in children because of concerns regarding radial-artery size, they said.
