| Popis: | Background Visualizing the lymphatic system and recording the spatial relations between the subclavian lymphatic trunk (SLT) and the surrounding anatomical structures will improve radiotherapy treatment planning for breast cancer patients with lymphatic involvement. An experimental approach to retrogradely fill the SLT with contrast agent was explored. Methods Six Thiel embalmed specimens were bilaterally dissected in the cervical and clavicular region to optimize the new experimental approach. A conservative dissection with minimum distortion of spatial relations between different anatomical structures was developed. A pressure reservoir was created inside the venous angle to allow retrograde filling of the SLT under the influence of time and pressure. Results The new methodology proved feasible, showing successful pressure build-up inside the venous reservoir, resulting in filling of the proximal end of the subclavian lymphatic trunk. The pressures needed to significantly fill the subclavian lymphatic trunk proved to be higher than the pressures that the venous walls could withstand. Conclusions Thiel embalmed specimens proved useful for optimizing the experimental approach, but the embalming products could have negatively affected the vessel strength. The authors suggest that their method will be applied on fresh frozen specimens in future studies, to obtain SLT filling up to the axillary lymphatic plexus. Our findings also pointed out that there is still a lot to be learned about the anatomical variability of the SLT and its termination sites. The detailed description of our experimental approach offers valuable information for future lymphatic mapping studies. |
