Summary
Computed tomography (CT)-guided coil localization is a safe and effective method for pinpointing sub-fissural lung nodules before surgery. This technique ensures accurate localization for minimally invasive wedge resections using video-assisted thoracoscopic surgery (VATS).
Area of Science:
- Thoracic Surgery
- Diagnostic Imaging
- Pulmonology
Background:
- Sub-fissural lung nodules pose localization challenges for minimally invasive thoracic surgery.
- Accurate preoperative localization is crucial for successful wedge resection via video-assisted thoracoscopic surgery (VATS).
Purpose of the Study:
- To evaluate the safety, feasibility, and clinical efficacy of preoperative computed tomography (CT)-guided coil localization for sub-fissural lung nodules (LNs).
Main Methods:
- Retrospective analysis of 105 patients undergoing CT-guided coil localization and VATS wedge resection.
- Focus on 4 patients with sub-fissural LNs requiring trans-fissural coil placement.
- Assessment of coil localization procedure, VATS, and histopathological outcomes.
Main Results:
- Successful coil localization was achieved in all 4 patients with sub-fissural LNs.
- Minor complications included parenchymal hemorrhage (1 patient) and asymptomatic pneumothorax (1 patient).
- 100% technical success rate for wedge resection, with no coil dislodgement; nodules were adenocarcinomas in situ or benign.
Conclusions:
- CT-guided coil localization is a safe and feasible method for precisely locating sub-fissural lung nodules.
- This technique facilitates accurate targeting for VATS wedge resection, improving surgical outcomes.
- Coil localization offers a reliable solution for challenging nodule locations within the lung parenchyma.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
