Biopsy and drainage techniques in children

Abstract

Drainage and biopsy are mainstay procedures in pediatric interventional radiology. As in the adult population, percutaneous biopsy and fluid collection drainage can be performed almost anywhere in the body, in almost all organ systems, and for myriad indications. However, there are some technique differences in children. Radiation protection is paramount, requiring alterations in imaging and guidance. Children have unique sedation and anesthetic requirements, and smaller patients provide both advantages and disadvantages that require/allow for alteration of the procedural techniques. This article will focus on these differences and describe specific techniques applicable to pediatric patients.
