Image-guided fine needle aspiration technique has been widely used in various diagnostic and therapeutic procedures. However, if the target of the puncture is a malignant tumor, it is possible that tumor cells attached to the surface and core of the puncture needle may fall off, causing tumor cells to enter the puncture needle path and form needle path implantation metastasis, thereby reducing the patient's quality of life and treatment effectiveness. In this article, we have identified the causes of needle tract metastasis, elaborated on relevant measures to prevent tract metastasis, summarized the operating standards of fine needle puncture and the treatment methods for needle tract metastasis, in order to reduce the incidence of needle tract metastasis, improve the quality of life and treatment effectiveness of patients.
