DSA旋转重建技术与CT引导胸部肿瘤穿刺活检的对比研究

摘要

Objective To evaluate the value of clinical application in chest tumor biopsy by DSA rotating reconstruction technology and CT guided technology.Methods The 63 cases of chest tumors collected,38 cases of lung tumors,25 cases of mediastinal tumors.Applicating of CT and DSA scan and formulating puncture path,according to their respective descending thoracic tumor puncture guide way.DSA and CT guided traditional way from the success rate of puncture,operation time,X-ray exposure and complications were analyzed.Results 45 cases take CT guidance,18 cases take DSA guidance.60 cases,the pathological results achieved and positive rate was 95.2％.CT group success rate of first puncture in 68.9％ (31/45),DSA group 88.9％ (16/18),statistically significant.CT group pneumothorax rate 17.8 ％ (8/45),DSA group pneumothorax rate 11.1％ (2/18),no statistical difference.Operation time CT group (23.111 ± 4.281) minutes,DSA group (12.889 ± 3.693) minutes,with significantly statistical differences.CT group exposure (11.563±3.023) mGy,DSA group exposure (9.956±2.193) mGy,statistically significant.Conclusion The chest tumor puncture biopsy by DSA rotating reconstruction technique guided with flexible,fast and convenient,and superior to traditional CT with real-time monitoring,shorten the operation time,reduce the exposure,the success rate of first puncture aspects.%目的 评价数字减影血管造影(DSA)旋转重建技术与CT引导技术在胸部肿瘤穿刺活检中的临床应用价值.方法 收集胸部肿瘤63例,其中肺部肿瘤38例,纵隔肿瘤25例.应用CT及DSA进行扫描并制定穿刺路径,在各自引导方式下行胸部肿瘤穿刺.DSA与传统CT导引方式从穿刺成功率、手术时间、X线曝光量及并发症等方面进行对比分析.结果 45例采取CT引导,18例采取DSA引导.60例取得病理结果,阳性率95.2％.CT组中首次穿刺成功率68.9％ (31/45),DSA组88.9％ (16/18),有统计学差异.CT组气胸发生率17.8％(8/45),DSA组气胸发生率11.1％(2/18),无统计学差异.手术时间CT组(23.111±4.281) min,DSA组(12.889±3.693) min,有明显统计学差异.CT组曝光量(11.563±3.023) mGy,DSA组曝光量(9.956±2.193) mGy,有统计学差异.结论 DSA旋转重建技术引导胸部肿瘤穿刺活检灵活、快捷、方便,在实时监测、缩短手术时间、减少曝光量、首次穿刺成功率方面较传统CT优越.
