低剂量CT扫描在CT定位引导下椎体成形术中的应用价值

The Application Value of Low-Dose CT Scanning in CT Guided Vertebroplasty

目的探讨与分析低剂量CT扫描在CT定位引导下椎体成形术中的应用价值。方法选取2022年1月—2022年12月在甘肃省兰州市榆中县中医院诊治的108例骨质疏松性椎体压缩性骨折(OVCF)患者作为研究对象,根据随机数表法将患者分为研究组与对照组,每组54例。对照组给予传统数字X线摄影定位引导,研究组给予低剂量CT扫描定位引导,研究组与对照组都给予椎体成形术(PVP)治疗,记录与判定两组患者的预后情况。结果两组患者术后7 d的疼痛视觉模拟量表(VAS)评分都明显低于术前1 d,差异有统计学意义(P<0.05),研究组术后7 d的疼痛VAS评分显著低于对照组,差异有统计学意义(P<0.05)。两组患者术后3个月的腰椎Oswestry量表(ODI)评分都明显低于术前1 d,差异有统计学意义(P<0.05),研究组术后3个月的腰椎ODI评分显著低于对照组,差异有统计学意义(P<0.05)。两组患者术后3个月的Cobb角都明显低于术前1 d,差异有统计学意义(P<0.05),研究组术后3个月的Cobb角与对照组对比有显著降低(P<0.05)。研究组的一次穿刺成功率为98.15%,显著高于对照组的83.33%,差异有统计学意义(P<0.05),研究组患者的骨水泥注入量、骨水泥渗漏量都显著少于对照组,差异有统计学意义(P<0.05)。结论低剂量CT扫描在CT定位引导下椎体成形术中的应用能提高一次穿刺成功率,减少患者的骨水泥注入量、骨水泥渗漏量,促进缓解患者的疼痛,改善患者的腰椎功能,减小患者的Cobb角。

Objective To explore and analyze the application value of low-dose CT scanning in CT guided vertebroplasty.Methods From January 2022 to December 2022,108 cases of patients with osteoporotic vertebral compressibility fracture(OVCF)who were diagnosed and treated in Yuzhong County Hospital of Traditional Chinese Medicine,Lanzhou,Gansu were selected as the study subjects.Accorded to the random number table method,the patients were divided into 54 cases in study group and 54 cases in control group.The control group were received traditional digital X-ray imaging localization guidance,while the study group were received low-dose CT scanning localization guidance,and both groups were received percutaneous vertebroplasty(PVP)treatment.All the prognosis of the two groups of patients were recorded and compared.Result The diff erece between the pain VAS score at 7 days after the surgery and the score at the day before the surgery in either group of patients was statistically significant(P<0.05),with the former lower than the latter.And the lumbar ODI,Cobb angle were diff erent in both groups from the day before and 3 months after the surgery,and these indicators were also signifi cantly diff erent between groups at 3 months after the surgery(P<0.05),with the former lower than the latter.The success rates of puncture by a one-time attempt were 98.15%vs.83.33%in study group and control group,respectively(P<0.05).The amount of cement injection and cement leakage in study group were signifi cantly lower than those in control group(P<0.05).Conclusion The application of low-dose CT scanning in CT guided vertebroplasty can improve the success rate of puncture by a one-time attempt,reduce the amount of bone cement injection and leakage in patients,promote pain relief,improve lumbar function,and reduce Cobb angle.
