Summary
Metallic microcoils guided by computed tomography aid in precise localization for lung biopsies. This technique helps limit excised tissue and confirms complete lesion removal, improving surgical outcomes for small lung masses.
Area of Science:
- Interventional Radiology
- Thoracic Surgery
- Diagnostic Imaging
Background:
- Percutaneous biopsy techniques may not be suitable for all small lung lesions.
- Accurate localization is crucial for minimally invasive excisional lung biopsies.
- Preoperative guidance can optimize surgical planning and tissue sampling.
Observation:
- Metallic microcoils were placed under computed tomographic (CT) guidance for wire localization.
- This technique was employed prior to an excisional lung biopsy.
- The procedure was analogous to mammographic wire localization for breast masses.
Findings:
- CT-guided microcoil localization successfully identified the lung mass.
- The technique limited the amount of surgically excised lung tissue.
- Postexcision specimen radiography confirmed complete removal of the lung lesion.
Implications:
- CT-guided microcoil localization is a potentially valuable preoperative tool for excisional lung biopsies.
- This method can improve precision for small or difficult-to-access lung lesions.
- It may be particularly useful in cases with surrounding diseased parenchyma or lesions near the pulmonary root.
