目的：描述一种在超声引导下利用门静脉和支撑器获取滑膜活检标本的新方法。方法：对37例单发性或多发性关节炎患者进行经皮超声引导下滑膜活检。使用针、导丝和扩张器建立了通往规划区域的入口，通过它可以插入钳子和采集样本。结果：37例患者中，33例获得了具有代表性的滑膜组织，可用于病理组织学评估，成功率为89%。结论：超声引导下应用鞘引入器和弹性钳行滑膜活检的新方法适用于大部分关节甚至滑囊和肌腱鞘。该方法在大多数情况下为临床工作提供了足够的样本，但在接受这项有希望的技术用于科学目的之前，还需要进一步的工作。
Objective: To describe a new method for taking a synovial biopsy specimen under ultrasound guidance using portal and forceps.Methods: Percutaneous ultrasound guided biopsy was performed for 37 patients with mono- or polyarthritis as outpatients. A portal to a planned area was built using a needle, guiding wire, and dilators, through which forceps could be inserted and samples taken. Biopsy samples were taken from small and large joints, bursae, and tendon sheaths.Results: Representative synovial tissue in adequate amounts for histopathological evaluation was obtained in 33/37 cases - a success rate of 89%. The biopsy procedures were well tolerated, but one complication of skin infection was encountered.Conclusion: The new method of synovium biopsy under ultrasound guidance using sheath introducer set and flexible forceps can be performed on most joints and even bursae and tendon sheaths. The method gives sufficient samples for clinical work in most cases, but further work is needed before accepting this promising technique for scientific purposes.
