Introduction: Chest ports are typically inserted via the right internal jugular vein with the left side being utilized in certain patient populations. The purpose of this study was to evaluate the dynamic position of the chest port and catheter tip, comparing a demographically matched cohort of female breast cancer patients with right‐ or left‐sided chest ports. Methods: 142 female patients with breast cancer requiring chest port insertion for chemotherapy and imaging confirming catheter tip position initially with supine fluoroscopy and follow‐up with erect chest radiography over a 5‐year period were identified. Data points analyzed were catheter tip‐to‐carina distance and the distance from the port to the ipsilateral infraclavicular border. Intraprocedural measurements were taken in the supine position during chest port insertion and compared with follow‐up erect chest radiography. The catheter tip position was also allocated a zone within the venous system on both image sets to assess for significant retraction to a more proximal zone in the erect position. Imaging within 12‐months of chest port insertion was also screened to identify port‐related complications. Results: The whole cohort showed significant retraction of the catheter tip (cephalad) (p < 0.001) and protraction of the port (caudal) (p < 0.001). The median tip‐to‐carina distance decreased from 38.3 mm to 28.6 mm and the port‐to‐clavicle distance increased from 31.3 mm to 64.6 mm. Right‐sided chest ports had increased tip‐to‐catheter retraction (15 mm) compared with left‐sided (6.9 mm) (p = 0.310). A complication was identified in 8.5% of the right‐sided and 11% of the left‐sided ports. Zone migration was significantly associated with the occurrence of a complication in left‐sided ports (p = 0.023). Conclusion: When assessing chest port catheter tip position between supine and erect radiographic studies in female patients with breast cancer, retraction cephalad will occur and this is more apparent in right‐sided ports. Change in catheter tip position was not associated with a significant increase in complication rate unless it occurred in left‐sided ports where zone migration was evident. [ABSTRACT FROM AUTHOR] |
