ITB pumps are widely used in the treatment of intractable spasticity for many clinical indications, including cerebral palsy and spinal cord injury. High-dose intrathecal administration places the patient at significant risk for withdrawal in the event of device malfunction, necessitating rapid and complete evaluation of the pump-catheter system. This article reviews the approach to imaging evaluation of ITB pump-catheter systems, with specific emphasis on radiography, fluoroscopy, CT, and nuclear scintigraphy.
ITB 泵广泛应用于多种临床适应证的难治性痉挛治疗,包括脑瘫和脊髓损伤。鞘内大剂量给药会使患者在发生器械故障时面临停药的巨大风险,因此需要快速、全面地评估泵-导管系统。本文回顾了 ITB 泵-导管系统的影像学评估方法,重点介绍了 X 线摄影、透视、CT 和核闪烁成像。
