Treatment of recurrent mediastinal lymph node metastasis using CT-guided nontranspulmonary puncture interstitial implantation of 125I seeds: Evaluation of initial effect and operative techniques

Treating recurrent mediastinal lymph node metastasis using CT-guided nontranspulmonary puncture interstitial implantation of 125I seeds is safe and effective, with minimal trauma, evident local therapeutic effects, and does not damage lung tissue. However, comprehensive application of multiple puncture assistive technologies, and skill, is required due to the important, anatomically complex structures in the mediastinum.
