    Area of Science:

    • Pulmonology
    • Medical Devices
    • Diagnostic Procedures

    Background:

    • Percutaneous lung biopsy is crucial for diagnosing lung conditions.
    • Existing biopsy needles may have limitations in diagnostic yield or complication rates.

    Purpose of the Study:

    • To evaluate the efficacy and safety of a newly designed three-pronged aspiration needle for percutaneous lung biopsies.
    • To determine the diagnostic accuracy and complication profile of this specialized needle.

    Main Methods:

    • A prospective study involving 151 patients undergoing 166 percutaneous lung biopsies.
    • Utilized a specially designed three-pronged aspiration needle for tissue acquisition.
    • Assessed diagnostic yield and recorded all complications post-procedure.

    Main Results:

    • A correct diagnosis was achieved in 141 out of 151 patients, yielding a diagnostic accuracy of 93.3%.
    • Minor complications were observed, including pneumothorax in 7.8% of cases and pulmonary hemorrhage with hemoptysis in 2.4% of cases.

    Conclusions:

    • The three-pronged aspiration needle is a highly effective tool for percutaneous lung biopsy, offering excellent diagnostic accuracy.
    • The procedure demonstrates a favorable safety profile with a low incidence of minor complications.
