A CT-guided pulmonary nodule-marker system successfully localized small nodules for thoracoscopic resection in all cases. This system demonstrated a high success rate with minimal complications, proving safe and accurate for guiding these procedures.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Medical Imaging

Background:

  • Accurate localization of small pulmonary nodules is crucial for successful thoracoscopic resection.
  • Minimally invasive techniques aim to reduce patient morbidity and improve outcomes.

Purpose of the Study:

  • To evaluate the efficacy and safety of a CT-guided pulmonary nodule-marker system.
  • To determine the success and complication rates of this system prior to thoracoscopic resection.

Main Methods:

  • A total of 25 pulmonary nodules in 24 patients were marked using a CT-guided wire system.
  • Lesion characteristics, intervention time, complications, and thoracoscopic success rates were assessed.

Main Results:

  • The marker system was successfully placed in all 25 nodules within an average of 7.5 minutes.

  • Minimal pneumothoraces occurred in 5 patients without requiring chest drains; no bleeding complications were noted.
  • All nodules were successfully resected thoracoscopically, with one instance of guide-wire dislocation managed successfully.

    • Conclusions:

    • CT-guided placement of the pulmonary nodule-marker system is a safe and accurate method.
    • This system effectively guides the localization of small pulmonary nodules for thoracoscopic resection.
