Background and objectives: To investigate the feasibility and safety of ultrasound-guided totally implantable venous access ports (TIVAPs) via the right brachiocephalic vein (BCV) in pediatric patients.
Methods: A single-institute retrospective review was performed on 35 pediatric patients with predominantly hematological malignancies (88.6%) who underwent TIVAP implantation via ultrasound-guided right BCV approach from July 2018 to June 2021. The catheter tip was adjusted to be positioned at the cavoatrial junction under pulsed fluoroscopic guidance. Technical success rate, procedural information, and TIVAP-related complications were evaluated.
Results: All the pediatric TIVAP devices were successfully implanted via right BCV access. Venous access was successful by first attempt in 32 children (91%), two cases (5.7%) required a second attempt, and one patient (2.9%) required a third attempt. The mean procedural time was 44.6 ± 6.4 minutes (range: 34-62 minutes). No intraoperative complications occurred. The average TIVAP indwelling time was 564 ± 208 days (range: 193-1014 days), with a cumulative 19,723 catheter-days. Overall, three patients (8.6%) experienced four postoperative complications (two cases of local hematoma and two catheter dysfunctions) at a rate of 0.2 per 1000 catheter-days. No other complications such as wound dehiscence, delayed incision healing, catheter-related thrombosis (CRT), catheter malposition/fracture, surgical site infection, catheter-related bloodstream infection (CRBSI), pinch-off syndrome, and drug extravasation were observed during follow-up.
Conclusions: Ultrasound-guided right BCV access for TIVAP placement in pediatric patients appears to be technically feasible, safe, and effective. Further large-sample, prospective studies are warranted.Reference:
