An Alternative Central Venous Access Route for Pediatric Patients with Chronic Critical Illness: The Transhepatic Approach.

Abstract

To evaluate the safety and functionality of the transhepatic approach as an alternative route for central venous catheterization in pediatric patients with chronic critical illness. The study included data of 12 chronic critically ill pediatric patients who underwent central venous catheterization with transhepatic approach. The indications, procedure details, mean patency time, and catheter-related complications were retrospectively analyzed. A total of 16 central venous catheters were placed through the transhepatic approach. A 5F port catheter was used in eight attempts, a 5F PICC in two attempts, and an 8-14F Hickman-Broviac catheter in six attempts. All procedures were performed with technical success. The mean patency time of the catheters was 132.1 d (range: 12-540 d). In the long-term follow-up, catheter-related sepsis was detected in a patient, and six catheters lost functionality due to malposition. The transhepatic approach is a safe and functional alternative route for central venous access in chronic critically ill pediatric patients requiring long-term vascular access. The procedure using ultrasonography and fluoroscopy can be performed with high technical success. In the long-term follow-up, Dacron felt cuff tunneled catheters placed in the subcostal space with a transhepatic approach remained functional for a long time.
