FIGURE 1 Images of ultrasound-guided placement of TIVAP via the right BCV in a 25-month-old child with retinoblastoma.
A: The ultrasound probe was placed in the right supraclavicular region to obtain a longitudinal view of the right BCV (*), and the access needle (white arrows) was advanced into the BCV. B: Fluoroscopy at procedure end shows that the injection port was implanted in the right infraclavicular area, and the catheter tip (white arrow) was located at the cavoatrial junction. C: The skin incision of venipuncture is located in supraclavicular site close to the neck, measuring 3-mm-length; the port pocket incision is located in upper chest wall, measuring approximately 2-cm-length, respectively. (Indicates the lung.)
FIGURE 2 Clinical process of subcutaneous hematoma after TIVAP implantation in a 2-month-old, 6.3-kg-weighted infant with acute lymphoblastic leukemia.
A: During the first week after surgery, the hematoma adjacent to the port pocket and tunnel was confirmed by ultrasound, which enlarged progressively. B, C: Wet compress with 25% magnesium sulfate solution and a transparent patch followed by elastic bandage for pressure dressing was applied for 3 days. D: Hematoma resolved two months later. (White arrow indicates the skin incision at the venipuncture site.)
