Abstract:
Objective: To observe movement of catheter tip of chest wall access port implanted via the internal jugular vein and impact factors when changing from supine to vertical positions. Methods: Data of 171 patients underwent implantation of chest wall access port via the internal jugular vein and chest X-ray films on supine and vertical position postoperatively were retrospectively analyzed, and the distance from the tracheal protuberance to catheter tip was measured. Pearson correlation analysis and multivariate regression analysis were performed to observe the impact factors of moving distance of catheter tip. Results: Changing from supine to vertical position, the catheter tip was inclined to cephalad movement, and the mean moving distance was (15.82±16.87)mm. The distance of catheter tip movement was positively correlated with gender (P=0.039) and sebum thickness (P=0.011) and negatively correlated with indwelling length of catheter (P=0.039). Conclusion: The catheter tip of chest wall access port implanted via the internal jugular vein tends to shift cephalad when changing from supine to vertical position, and the distance of movement is related to patient's gender, sebaceous thickness and the length of indwelling catheter.
