CT-guided 125I seed implantation for retroperitoneal lymph node metastases：its technical points / 介入放射学杂志

ABSTRACT

Objective To introduce several commonly used puncture techniques for retroperitoneal lymph node metastases in order to provide technical guidance in performing 125I seed implantation therapy. Methods The puncture methods used at authors’ interventional department in performing 125I seed implantation therapy for retroperitoneal lymph node metastases were summarized. Results The commonly used puncture methods included parallel needle puncturing technique , trans-viscera puncturing technique , broadening path puncturing technique and coaxial needle puncturing technique. Conclusion An effective combination use of various puncturing techniques to uniformly implant the radioactive 125I seeds into the lesion can improve the therapeutic result and reduce the occurrence of complications.
