ULTRASOUND-GUIDED SYNOVIAL BIOPSY: A PRELIMINARY RESULT
Main Article Content
Abstract
Background: Synovial thickening is a common manifestation of various arthropathies. Apart from joint fluid aspiration, synovial membrane sampling plays a fundamental role in determining the nature of the diseases. Ultrasound-guided needle biopsy of the synovial membrane has been recognized as a safe, simple, and effective procedure. This paper aimed to assess the preliminary results of ultrasound-guided synovial biopsy at a single center. Methods: Data from 11 patients with synovial thickening from September 2019 to October 2022 at Hue University of Medicine and Pharmacy Hospital were retrospectively analyzed. Tissue sampling was collected by using an automatic biopsy gun with 16G or 18G needle. Needle size, length of core, number of passes and procedure endpoints were down to the operators. Results: The median age was 49 (range, 21-86 years), male: female ratio was 7:4. Knee joint was the most frequent site of biopsy (8/11 cases). The average number of samples was 3.63 (range, 1-5 samples), and 10-15mm in length. Technical success rate was 100%. All of the specimens were pathologically conclusive given a diagnostic yield of 100%. No intra and post procedural complications were observed. Conclusion: Ultrasound-guided synovial biopsy is a safe and effective method to determine the nature of arthropathies
