Computed tomography-guided trans-pulmonary-hepatic approach coil localization for pulmonary nodules near the right lung base.

Introduction: Video-assisted thoracoscopic surgery (VATS)-guided diagnostic wedge resection (WR) is frequently used for removal of pulmonary nodules (PNs). Preoperative computed tomography (CT)-guided coil localization (CL) is often used for guidance.

Aim: To evaluate the feasibility, safety, and effectiveness of CT-guided trans-pulmonary-hepatic approach CL of PNs near the right lung base.

Material And Methods: Consecutive patients with PNs who underwent CT-guided CL followed by VATS-guided WR at our center from January 2018 to December 2020 were analyzed.

Results: One hundred and twenty-two patients with PNs underwent CT-guided CL followed by VATS-guided WR at our center. Of them, 5 (4.1%) patients had PNs near the right lung base and underwent the CT-guided trans-pulmonary-hepatic approach CL procedures. The technical success rate of CL was 100%. The VATS-guided WR was 100% successful. No patient required thoracotomy.

Conclusions: CT-guided trans-pulmonary-hepatic approach CL for PNs located near the right lung base is technically feasible.
