Pediatric abdominal arterial intervention using a steerable microcatheter through an introducer with 4-F outer diameter: report of two cases

Abstract

In pediatric arteriography, vascular complications are more common than in adults; thus, the use of the smallest catheter to accomplish the objective of the procedure is recommended. We describe two pediatric cases in which abdominal arterial embolization and arteriography were performed with steerable microcatheters without conventional diagnostic catheters. Additionally, we used an introducer with an outer diameter of 4-F in a Mini Access Kit (Merit Medical, South Jordan, UT) as a vascular sheath to reduce sheath size. We believe that this technique may be feasible and safe for abdominal arterial interventions in children.
