[Indocyanine Green( ICG) Fluorescence Imaging to Visualize Intersegmental Plane].

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Medical Imaging

Background:

• Anatomical segmentectomy is indicated for early-stage lung cancers located centrally.
• Accurate identification of the inter-segmental plane is crucial for successful segmentectomy.

Purpose of the Study:

• To evaluate two distinct indocyanine green (ICG) fluorescence techniques for intraoperative visualization of the inter-segmental plane during lung segmentectomy.
• To discuss the advantages and disadvantages of each ICG fluorescence method.

Main Methods:

• Systemic intravenous administration of ICG after segmental pulmonary artery ligation.
• Insufflation of diluted ICG into the segmental bronchus via bronchoscope.
• Visualization of segmental alveoli and inter-segmental planes using ICG fluorescence thoracoscopy.

Main Results:

• Both ICG fluorescence techniques successfully visualized the inter-segmental plane.
• The study discusses the respective benefits and limitations of each method.
• ICG fluorescence imaging integration with robotic surgery was noted.

Conclusions:

• ICG fluorescence imaging provides effective visualization for anatomical segmentectomy.
• These techniques can potentially broaden the scope of atypical segmentectomy procedures.
• ICG fluorescence imaging holds promise for diverse thoracic surgery applications.
