Trial Title: Radial Versus Femoral Arterial Access for Cerebral Angiography in Adolescents

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: OTHER
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Age 8-18 years~2. Planned cerebral or supra-aortic angiography for clinical reason~3. Positive modified Allen's test using a pulse oximeter on the index finger.~4. 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:~1. Age \<8 years~2. 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.~3. 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.~4. Failed modified Allen's test with pulse oximetry~   -
