Summary
Preoperative barium marking using virtual bronchoscopic navigation accurately guided surgeons to small lung lesions. This minimally invasive technique aids in precise localization for thoracoscopic surgery, improving resection accuracy.
Area of Science:
- Pulmonology
- Thoracic Surgery
- Medical Imaging
Background:
- Accurate localization of small peripheral pulmonary lesions is crucial for successful thoracoscopic surgery.
- Traditional methods may face challenges in precisely identifying deep or subtle lung nodules.
Observation:
- A 77-year-old woman with a 9x7 mm ground-glass opacity in the right lower lung lobe underwent preoperative marking.
- Virtual bronchoscopic navigation guided an ultrathin bronchoscope to the lesion's specific bronchial segments (B8aii, B6bii).
- Barium was infused via a specialized catheter, creating a visible marker.
Findings:
- The barium marker was clearly visualized during thoracoscopic surgery using fluoroscopy.
- This facilitated accurate determination of the resection area.
- Pathological examination confirmed atypical adenomatous hyperplasia, with no complications reported.
Implications:
- Preoperative barium marking with virtual bronchoscopic navigation is an effective and safe method for localizing small peripheral pulmonary lesions.
- This technique can enhance precision in thoracoscopic lung resections.
- It offers a potentially valuable tool for improving surgical outcomes in minimally invasive thoracic procedures.
