Percutaneous pulmonary aspiration biopsy using the Chiba needle
Journal of the Canadian Association of Radiologists
|September 1, 1979
Summary
The Chiba needle enables accurate cytologic diagnosis for lung lesions via percutaneous needle aspiration. This minimally invasive technique demonstrated a 94% accuracy rate with an acceptable complication profile in 35 patients.
Area of Science:
- Pulmonology
- Oncology
- Radiology
Background:
- Percutaneous needle aspiration is a key diagnostic tool for lung lesions.
- Optimizing needle selection and technique is crucial for diagnostic yield and patient safety.
Purpose of the Study:
- To evaluate the efficacy and safety of the Chiba needle for percutaneous needle aspiration of lung lesions.
- To determine the accuracy and complication rate associated with this procedure.
Main Methods:
- The Chiba needle was utilized for percutaneous needle aspiration in 35 patients with lung lesions.
- Two needles were used per patient during the same procedure.
- Aspirates were analyzed for cytologic diagnosis of malignancy.
Main Results:
- The overall accuracy rate for diagnosing malignancy was 94%.
- True positive for malignancy: 23 patients; True negative for malignancy: 8 patients.
- Minor complications included small pneumothoraces in six patients, with only one requiring intervention. No significant hemoptysis occurred.
Conclusions:
- The Chiba needle is effective in obtaining adequate aspirates for cytologic diagnosis of lung lesions.
- The complication rate associated with using two Chiba needles appears acceptable.
- This method offers a safe and accurate approach to diagnosing lung malignancies.
