腰椎间盘突出症手术治疗的MRI影像学疗效评价

Therapeutic Evaluation of MRI Imaging of Surgical Therapy for Lumbar Disc Herniation

目的探讨椎间盘突出症手术治疗的MRI影像学疗效评价。方法选取医院收治的腰间盘突出症患者32例作为研究对象,术前及术后均行磁共振成像(MRI)检查,评估临床疗效。结果本组32例患者手术均成功,治疗优良率为87.5%。本组患者中2例出现术后并发症,经针对性处理后均明显好转;治疗后VAS评分为(3.07±1.06)分较治疗前低,JOA评分为(23.94±3.27)分较治疗前高,差异具有统计学意义(P<0.05);治疗后硬膜外压痕矢径、硬膜外压痕纵轴、椎间隙高度分别为(3.98±1.85)mm、(9.52±4.06)mm、(9.05±2.61)mm均较治疗前低,差异具有统计学意义(P<0.05);治疗后软骨退化程度较治疗前轻,差异显著,具有统计学意义(P<0.05);术后28例椎间组织上T2WI明显回升;32例神经根增粗、变性明显改变,T2WI信号减低。结论 MRI可作为评价椎间盘突出症术后疗效的重要影像学方式。

Objective To explore the therapeutic evaluation of MRI imaging of surgical therapy for lumbar disc herniation. Methods 32 cases of patients with lumbar disc herniation admitted into the hospital were selected as the research object. Magnetic resonance imaging （MRI） was carried out before and after surgery and the clinical efficacy was evaluated. Results All the 32 patients in the group were operated successfully and the excellent and good rate was 87.5%. There were postoperative complications appearing in 2 cases and after the targeted treatment, they were significantly improved;VAS score after the treatment was （3.07±1.06） which was lower than that before the treatment. JOA score was （23.94±3.27） which was higher than that before the treatment and the differences were statistically significant （P〈0.05）; after the treatment, the epidural indentation radius vector, epidural indentation longitudinal axis, intervertebral space height respectively were （3.98±1.85）mm, （9.52±4.06）mm and （9.05±2.61） mm which were lower than those before the treatment and the differences were statistically significant （P〈0.05）;After the treatment, the degree of cartilaginous degradation was lighter than that before the treatment and the difference was statistically significant （P〈0.05）; There 28 cases of significantly rebounded intervertebral tissue T2WI; 32 cases of nerve root thickening, significantly changes of degeneration and decreasing T2WI signal. Conclusion MRI can be used as an important imaging method to evaluate the efficacy of the treatment of lumbar disc herniation.
