Computed tomography-guided percutaneous puncture injection of methylene blue mixed with autologous blood for preoperative localization of pulmonary nodules: analysis of 407 cases

Background

Computed tomography (CT)-guided preoperative localization using methylene blue mixed with autologous blood is a commonly used technique for pulmonary nodules. However, its safety profile and risk factors for complications remain to be fully elucidated. This study aimed to evaluate the safety and complication risk of this technique and to explore the risk factors associated with the occurrence of complications.
