Indocyanine green-fluorescence (ICGF) navigation is a safe and effective method for thoracoscopic anatomical segmentectomy (TS-S). This technique aids in clearly demarcating lung segments, ensuring successful surgical outcomes with minimal complications.
Area of Science:
- Thoracic Surgery
- Surgical Navigation
- Medical Imaging
Background:
- Thoracoscopic anatomical segmentectomy (TS-S) is a complex procedure.
- Accurate visualization of lung segments is crucial for successful TS-S.
Purpose of the Study:
- To evaluate the feasibility and efficacy of TS-S using 3D-CT reconstruction and ICGF navigation.
- To assess the safety and effectiveness of ICGF for guiding TS-S.
Main Methods:
- Twenty TS-S procedures were performed for lung cancers and metastases.
- Preoperative 3D-CT reconstruction created virtual intersegmental planes.
- Intraoperative ICGF navigation guided the division of lung segments.
Main Results:
- ICGF provided clear demarcation in 95% of patients.
- All TS-S procedures were successfully completed.
- The method demonstrated a favorable safety profile with no complications.
Conclusions:
- ICGF navigation is a safe and effective technique for TS-S.
- This method enhances the precision and feasibility of lung segmentectomy.
