螺旋CT导向下臭氧消融术治疗腰椎间盘突出症的疗效观察及护理配合

SPIRAL CT GUIDED O_3 INJECTION FOR THE TREATMENT OF LUMBAR DISC HERNIATION

目的探讨螺旋CT导向下臭氧消融术治疗腰椎间盘突出症的临床疗效及护理配合。方法51例腰椎间盘突出症患者于CT导向下行臭氧消融术。突出物为旁中央型者经神经根与硬膜囊之间穿刺突出物达盘内,突出物为外侧型者经神经根外侧、小关节突内缘穿刺突出物达盘内,分别于盘内及突出物中央注射浓度为60μg/mL的臭氧5~15 mL。结果注射臭氧后CT扫描显示臭氧在间盘内呈裂隙状、髓核腔内积聚状、弥散分布状。臭氧注射后神经根轮廓全部显露、＂淹没征＂消失者占28%,神经根大部分显露、＂淹没征＂部分消失者占48%,神经根显露不明显者占24%。结论螺旋CT导向下臭氧消融术治疗椎间盘突出症安全、准确,疗效满意。

Objective To explore the effect of Spiral CT guided O3 injection in the treatment of lumbar discherniation. Methods All 51 patients with herniation of lumbar disc were treated with O3 injection under the guidance of Spiral CT. The puncture rout for midline or paramidline hemiated nucleus pulposus （HNP） passed between the nerve root and dural sac to disk, and that for posterolateral HNP between the nerve root and the inner margin of articular facet to disk. A total of 5 - 15 mL of ozone with concentration 60μg/mL were injected both to disk and the center of HNP. Results After the injection of ozone , the ozone was distributed as localized shape, cranny shape and dispersion shape. After the treatment, 28 % HNP the obliteration of nerve root vanished, 48 % partially and 24 % with nerve root remaining obliterating. Conclusion Spiral CT guided 03 injection is an accurate, safe and effective method in the treatment of lumbar disc herniation.
