Radial Versus Femoral Arterial Access for Cerebral Angiography in Adolescents
Stopped: insufficient enrolment-radial access for neuroangiography is now accepted as clinical standard.

Plain-language summary
This study will compare radial vs femoral access for angiography in adolescents. Neuroangiography and neurointerventions are predominantly performed via femoral access, which has several limitations and complications - pain and discomfort, arterial occlusion, retroperitoneal hemorrhage, activity limitations, and increased admissions. Transradial angiography has shown promise to circumvent these problems, but this has not been studied in children, whose unique anatomical and physiological aspects require that this be evaluated rigorously.

Inclusion criteria
✓. Age 8-18 years
✓. Planned cerebral or supra-aortic angiography for clinical reason
✓. Positive modified Allen's test using a pulse oximeter on the index finger.
✓. Radial artery axial maximal diameter of \> 2.0 mm measured on a cross-sectional B-mode ultrasound of the distal radial artery, 2-3 cm proximal to the radial styloid, at the anticipated needle puncture site -
Exclusion criteria
✕. Age \<8 years
✕. Radial artery internal maximal of diameter 2.0 mm or less (measured on cross-sectional ultrasound 2-3 cm proximal to the radial styloid at the planned puncture site) - these patients would be converted to femoral access without radial artery puncture but would be assessed in the radial artery group as part of an intention-to-treat analysis.
✕. Conversion to intervention (as opposed to diagnostic cerebral angiogram) during the procedure, as this will likely require a larger (femoral) access sheath; again such patients will still be assessed as part of the intention-to-treat analysis.
