title: Pediatric cerebral angiography: analysis of utilization and findings.
abstract: Pediatric neuroendovascular procedures are being performed with increasing frequency, for various indications. Reported here is the experience of interventionally trained neurologists performing pediatric cerebral diagnostic angiography between August 1, 2005, and April 30, 2008, at a single tertiary institution. Data regarding patient demographics, diagnostic indication and angiographic diagnosis, procedural complications, and procedural specifications were recorded to assess practice patterns and to track procedural morbidity. In all, 42 patients had 46 procedures during the study period. Mean age was 9.97 years (standard deviation S.D. = 5.39; range, 0.3-18 years); 22/42 were male (52%). Known or suspected vascular malformation was the diagnostic indication for 20 patients; of these, 12 had an arteriovenous malformation, 5 had venous abnormalities, and 3 exhibited no angiographic vascular malformations. In 13 total procedures there was no angiographic pathology. General anesthesia was used in 29/46 procedures (63%). A total of 190 cerebral arteries were individually selected, with a mean number of vessels catheterized of 4.1 (S.D. = 1.7) per procedure. No procedural thromboembolic complications, iatrogenic arterial dissection, or neurologic or vascular access site complications occurred. In conclusion, pediatric cerebral angiography seems to be generally safe, although there should be a strong diagnostic indication, given the inherent procedural risk.
