Pediatric interventional radiology: Indications, techniques, and management

This course develops a practical approach to pediatric interventional radiology. Radiologic intervention in the pediatricage group is possible by attending to the care and special needs of the child. The authors also emphasize their approach to patient preparation, sedation and anesthesia, nursing care, monitoring of the patient during the procedure, and follow-up care. The course is divided into nonvascular and vascular sections. The discussion of nonvascular procedures focus on the chest and the GU and GI systems. Biopsy techniques and drainage of effusions and abscesses within the chest are discussed. A variety of GU procedures are presented including insertion of a nephrostomy tube and percutaneous tract dilation for placement of internal stents, percutaneous stone removal, and percutaneous surgery for pyeloplasty. The authors approach to percutaneous pyeloplasty is briefly discussed. Intervention within the GI system includes percutaenous aspiration, drainage, and biopsies. Emphasis is placed on the selection of embolic agents and catheter delivery systems, techniques, and current treatment concepts. The authors describe experience with embolization of vascular malformations, renovascular disease, uncontrollable hemorrhage, and selected neoplastic processes. Comments on the indications for and techniques of transluminal angioplasty and fibrinolytic therapy in children conclude the lecture
