Abstract
We describe a case of a 63-year-old lady with an incidental small right upper lobe ground glass opacity (GGO) lesion, who had history of open-heart surgery with bypass grafts for coronary artery disease. Video-assisted thoracic surgery (VATS) excisional biopsy with pre-operative localization was planned. Localization by percutaneous approach is challenging due to position of GGO shielded by both the scapular and ribs. Electromagnetic navigation accuracy may be affected by steel sternal wires but its effect has not been reported on literature. Both virtual and electromagnetic navigation bronchoscopy platforms were used with real-time cone-beam CT confirmation in the hybrid operating room to perform dye marking. Both navigation methods successfully marked the GGO for lung resection. Our case demonstrated that the accuracy of electromagnetic navigation in the presence of steel sternal wire is satisfactory for dye marking and the use of intra-operative cone-beam CT in hybrid operating room is invaluable for the success of navigational bronchoscopy.
