Summary
Pulmonary sequestration lung resections are safer using 3D-CT imaging and indocyanine green (ICG) fluorescence navigation. This combined approach aids in identifying critical blood vessels and guiding precise surgical removal.
Area of Science:
- Thoracic Surgery
- Surgical Imaging
- Congenital Lung Abnormalities
Background:
- Pulmonary sequestration presents significant bleeding risks during surgical resection.
- Accurate identification of aberrant vasculature is crucial for safe lung resection.
Purpose of the Study:
- To describe a combined surgical technique for pulmonary sequestration using 3D-CT and ICG fluorescence navigation.
- To evaluate the safety and efficacy of this technique in patients undergoing lung resection.
Main Methods:
- Utilized three-dimensional computed tomographic (3D-CT) imaging for preoperative planning and intraoperative vessel identification.
- Employed intraoperative intravenous administration of indocyanine green (ICG) for fluorescence navigation.
- Performed lung resection for pulmonary sequestration in three cases using this combined approach.
Main Results:
- Successfully identified and divided aberrant arteries and draining veins in all three cases.
- Achieved precise delineation of resection margins using 3D-CT and ICG fluorescence.
- Completed lung resections safely without life-threatening bleeding complications.
Conclusions:
- The combination of 3D-CT imaging and ICG fluorescence navigation offers a safe and effective strategy for lung resection in pulmonary sequestration.
- This technique enhances intraoperative visualization of critical vascular structures, minimizing surgical risks.
