摘要
目的探讨椎间盘造影对经皮穿刺腰椎间盘激光汽化减压术(PLDD)的意义。方法对50例腰椎间盘突出症先作腰椎间盘造影,再对病变椎间盘进行PLDD治疗。对造影图像进行Dallas分级,以JOA评分为疗效指标,比较不同Dallas分级的病变椎间盘治疗效果。结果正常椎间盘造影结果均为Dallas0～Ⅰ级,病变椎间盘DallasⅡ级组34例,DallasⅢ级组16例,两组患者术前JOA评分差异无显著性,术后JOA评分DallasⅡ级组为(21.2±4.4)分,DallasⅢ级组(14.2±3.8)分,两组数据差异有显著性(P<0.05)。结论DallasⅡ级的病变椎间盘更适合行PLDD治疗,与CT、MRI相结合,椎间盘造影可以有效地选择适合PLDD治疗的患者。
Objective To evaluate the therapeutic value of discography in the percutaneous laser lumbar disc decompression. Methods Fifty patients with lumbar disc herniation received discography and the herniated discs were treated by PLDD. The patients were divided into 2 groups by the discography images and graded according to the Dallas standard. The curative grade was assessed by the JOA standard. Results The discography images of all the normal discs were Dallas 0-Ⅰ grade. Thirty- four herniated discs displayed Dallas Ⅱ grade, and 16 herniated discs displayed Dallas Ⅲ grade. The JOA score of the patients in two groups before PLDD showed no significant difference. After PLDD therapy, the average JOA score in Dallas Ⅱ patient group was 21.2 ± 4.4 while the score in Dallas Ⅲ group was 14.2 ± 3.8, showing significant statistical difference （P〈0.05）. Conclusion The herniated discs displayed Dallas Ⅱ grade are more suitable for PLDD therapy than those displayed the Dallas Ⅲ grade. Combined with CT and MRI, discography could be helpful in the selection of suitable cases for PLDD.
