A nomogram model for predicting pneumothorax after CT-guided localization of pulmonary nodules using autologous blood and methylene blue.

ABSTRACT:

Background

The widespread use of low-dose chest computed tomography (CT) has significantly increased the early detection rate of small nodules. Existing localization methods have certain limitations. Preoperative localization using autologous blood combined with methylene blue has garnered attention due to its dual advantages. This study aims to evaluate the safety and pneumothorax risk of CT-guided preoperative localization using this technique and explore the risk factors associated with pneumothorax occurrence.

Methods

This retrospective study included 112 patients who underwent CT-guided preoperative lung nodule localization using autologous blood and methylene blue between November 2019 and November 2024 at The First Hospital of Putian. Patient demographics, imaging cha
