Abstract:
Objective:This study aimed to evaluate the clinical utility of intraoperative venography in image-guided chemoport insertion, with a focus on catheter tip positioning and procedural safety.
Methods:We retrospectively reviewed 270 patients who underwent chemoport insertion via the internal jugular vein between July 2020 and April 2024. Intraoperative venography was used to localize the SVC–RA junction. Patient demographics, catheter tip location, complications, and clinical outcomes were analyzed.
Results:Venous stenosis was detected in 9.5% of patients without prior central catheterization and in 23.5% of those with a history of prior access; the difference was not statistically significant (p=0.065). Two cases of severe stenosis required balloon angioplasty before chemoport insertion. Although all catheter tips were positioned intraoperatively within 2 cm below the SVC–RA junction, only 61.5% remained in the intended location on postoperative chest x-ray. Superior migration occurred in 65.2% and inferior in 20.4%, but differences between planned and postoperative catheter tip positions were not significantly associated with complications (p=0.613). Left-sided insertions required significantly longer catheters than right-sided ones (p<0.001), while height, weight, and BMI were not predictive of catheter length.
Conclusion:Intraoperative venography can be a useful tool for guiding chemoport insertion, as well as for identifying and managing venous stenosis.
