超声介入技术在慢性疼痛治疗中的应用

Application of ultrasound-guided intervention in the treatment of chronic pain diseases

近年来，超声成像技术在疼痛介入治疗领域的应用逐年增多。其主要优势包括可避免患者及操作者的放射线暴露，以及可实时呈现软组织结构，包括神经、肌肉、肌腱和血管等的图像。后者明显提升了超声引导致痛神经阻滞及关节注射的精准性和安全性。由于骨性声影的存在，超声成像技术在用于轴神经阻滞时存在一定局限性。然而在经椎间孔硬膜外腔注射及选择性神经根注射治疗方面，该技术显现出良好的应用前景。

Uhrasonography has recently exploded in popularity for interventional pain procedures. The major advantages of which include the absence of radiation exposure for both patient and operator, and the real time visualization of soft tissue structures, such as nerves, muscles, tendons, and vessels. The latter is why uhrasound-guided pain nerve blocks and joint injection can improve their accuracy and safety. The limitation of ultrasonography is its use for many types of axial nerve injections because of bony and acoustic shadow artifact, but it does show some prospects in transforaminal epidural injection and selective nerve root block.
