Head and neck angiography in the pediatric population: single-center experience with indications, safety, feasibility, and technical differences among infants, childhood, and adolescents



Pediatric patients are candidates for head and neck endovascular procedures less frequently than adults. Data on utilization, feasibility, safety, and technical details of head and neck angiography in the pediatric population are scarce.



The authors performed a retrospective review of their center’s endovascular database to identify all patients ≤ 18 years of age who underwent diagnostic or interventional catheter-based angiography of the head and neck. Procedure-related variables for identified patients were compared across infancy (birth to 2 years), childhood (> 2–11 years), and adolescence (> 11–18 years).



One hundred twenty-one pediatric patients who underwent 274 angiogram procedures were included in this study. Of these angiograms, 197 were diagnostic and 118 were interventional (including 41 of the diagnostic angiogram procedures that were performed concurrently with the intervention). The most common indications for diagnostic angiograms were suspected vascular malformations in 52 cases (26.4%) and aneurysms in 23 (11.7%). The rate of positive findings on diagnostic angiograms ranged from 27.3% to 80% according to the indication. Access site–related complications were observed after 2 punctures (0.7%). Procedure-related complications occurred in 3 patients (1.1%). In adolescents, the rates of general anesthesia use and sheathless access were significantly lower (each p < 0.001), and the rates of radial artery access (p < 0.001); 5-French (5F) (p = 0.01), 6F (p < 0.001), and 8F (p = 0.03) access; and closure device usage (p < 0.001) were significantly higher. In infants, the rates of ultrasound guidance, 4F access, and failure of the primary puncture site were significantly higher (each p < 0.001).



Head and neck angiograms in the pediatric population were feasible and safe in the authors’ overall experience. Technical differences were observed across the infant, childhood, and adolescent groups, but safe outcomes were similar throughout these age ranges.
