Abstract:
Objective:To investigate the feasibility of using body surface marker localization method to determine the correct position of catheter tip (lower 1/3 of the superior vena cava or the junction of superior vena cava and right atrium) in totally implantable venous access port (TIVAP) implantation via internal jugular vein approach.Methods:The clinical data of 220 patients who underwent TIVAP implantation in Beijing Tongren Hospital, Capital Medical University from June 2019 to June 2021 were retrospectively analyzed. Among them, 168 patients used the internal jugular vein approach. According to the method implemented for determining the length of central venous catheter (CVC) during the operation, the patients were divided into two groups: 136 patients using the body surface marker localization method were defined as the study group; and the remaining 32 cases treated by the intraoperative X-ray fluoroscopic localization method were defined as the control group. The difference in the excellent or good rate of CVC tip position immediately after implantation and the time of implantation was compared between the two groups. In addition, the correlation between the length of CVC indwelling, height, age, and the distance between the catheter tip and tracheal carina was analyzed for the patients with right and left internal jugular vein catheterization. Kolmogorov-Smirnov test was used for statistical distribution of measurement data. Normal distribution of measurement data was expressed as mean ± standard deviation ( ± s), independent sample t-test was used for comparison between groups. Chi-square test was used for comparison between counting data. With TIVAP catheter indenture length as dependent variable and height as independent variable, Pearson correlation analysis was performed, the relationship equation between ideal catheter indenture length and patient height was analyzed by unitary linear regression. Results:When the CVC tip was located at the second intercostal space, the third sternocostal joint and the third intercostal space, the corresponding probability of being in the correct position was 34.8%, 83.3% and 95.0% respectively. The third sternocostal joint or the third intercostal space had a higher probability of correct CVC tip location than the second intercostal space, and the difference were statistically significant ( P<0.001). Furthermore, there was no significant difference in the possibility of the CVC tip located in the correct position between the third sternocostal joint and the third intercostal space ( P=0.149). Compared with the control group (before adjusting catheter position), the proportion of excellent or good CVC position in the study group was significantly improved (94.1% vs 46.9%), and the difference was statistically significant ( χ2=41.99, P<0.001); while the total operation time was significantly shortened [(33.04±6.69) min vs (42.50±5.54) min], and the difference was statistically significant ( P<0.05). There was a linear correlation between the length of CVC insertion and height. Indwelling catheter length via right internal jugular vein approach (cm) =0.159× height (cm)-1.284 ( r=0.597, r2=0.356, P<0.001); length of catheter indwelling through the left approach (cm) =0.097× height (cm) + 12.139 ( r=0.322, r2=0.104, P=0.020). Conclusions:The third sternocostal joint or the third intercostal space would be the corresponding correct surface landmark of the CVC tip when the body surface marker localization method was adopted during the TIVAP implantation via the internal jugular vein approach. Compared with the intraoperative X-ray fluoroscopy localization, the operation time is significantly shortened with the application of the body surface marker localization method. This technique is simple and easy to master and has high reliability in determining the length of catheter and the position of CVC tip.
