Abstract:
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.
