Transradial Approach for Pediatric Diagnostic and Neurointerventional Surgery: Single-Center Case Series and...

Area of Science:

• Pediatric Cardiology
• Interventional Radiology
• Vascular Access

Background:

• Transradial approach (TRA) adoption in adults has increased.
• Limited data exists on TRA safety and feasibility in pediatric patients.
• This study evaluates TRA in children and compares it to existing literature.

Purpose of the Study:

• To assess the safety and feasibility of the transradial approach in pediatric neuroangiography.
• To compare outcomes of pediatric TRA with published literature.
• To identify factors contributing to successful pediatric TRA procedures.

Main Methods:

• Retrospective analysis of a prospectively maintained database of pediatric patients (≤18 years) undergoing neuroangiography via TRA.
• Systematic literature review of studies on pediatric transradial artery procedures (January 2000 - September 2021).
• Data collection included demographics, procedural details, complications, and outcomes. Statistical analysis involved descriptive statistics.

Main Results:

• Twenty-one pediatric patients (mean age 16.6 years) underwent diagnostic (71.4%) and interventional (28.6%) neuroangiography.
• All cases used ultrasound guidance and a 'radial cocktail' (verapamil-heparin-nitroglycerin).
• Low complication rates observed: 9.5% conversion to femoral access, 9.5% reversible vasospasm; no radial artery occlusion or permanent neurologic deficits.

Conclusions:

• Transradial approach is a safe and feasible option for pediatric neuroangiography.
• Routine ultrasound guidance, appropriate catheter selection, and prophylactic medications are key to success.
• Findings align with literature, supporting TRA's utility in pediatric vascular interventions.
