Abstract:
PURPOSE:To compare the success and infection rates of radiologic placement with those of surgical placement of tunneled central venous access catheters (TCVACs) in infants and small children. MATERIALS AND METHODS:In 17 pediatric patients, TCVACs were placed with vascular access under ultrasound or fluoroscopic guidance in the radiology department. In 29 other patients, TCVACs were placed with percutaneous puncture or surgical cutdown in the surgery department. RESULTS:Two (11%) of 18 attempts at radiologic placement were unsuccessful; six (38%) of the 16 radiologically placed catheters necessitated removal because of dislodgment, malfunction, or infection; six (38%) were electively removed; and four (25%) still function. Eight (23%) of 35 attempts at surgical placement were unsuccessful; 17 (63%) of the 27 surgically placed catheters required removal because of dislodgment, malfunction, or infection; nine (33%) were electively removed; and one (4%) still functions. CONCLUSION:The success and infection rates of radiologic placement of TCVACs were similar to those of surgical placement. Radiologic placement required fewer attempts and was slightly less expensive.
