Abstract
Background The objective of this study was to evaluate the feasibility, safety, and clinical
effectiveness of preoperative computed tomography (CT)-guided transfissural coil localization
(TFCL) of subfissural lung nodules.
Methods Five patients with lung nodules who underwent CT-guided TFCL before video-assisted
thoracoscopic surgery between November 2015 and December 2018 were included. Technical
success rates of TFCL and wedge resection were assessed, as well complications and
pathological results.
Results The technical success rate of TFCL was 100%. Two patients experienced parenchymal
hemorrhage around the needle path, and two patients experienced asymptomatic pneumothorax
after TFCL. The technical success rate of the wedge resection of lung nodules was
also 100%. The pathological diagnoses of the five nodules were minimally invasive
adenocarcinoma (n = 3), adenocarcinoma in situ (n = 1), and inflammatory nodule (n = 1).
Conclusion CT-guided TFCL is a safe and effective method for the preoperative localization of
subfissural lung nodules.
