目的对CT片加X线透视定位和CT激光定位线加体表标记定位法引导下的经皮胸肺穿刺活检术、穿刺方案的设计和影响穿刺成功率、准确率、并发症的发生率的因素进行探讨。方法对7例用CT片加X线透视定位、24例用CT定位共31例患者行胸肺部病灶穿刺活检术。结果穿刺成功率100%,诊断准确率为87.10%(27/31)。并发症:气胸发生率为22.58%(7/31),均观察1~4d后自愈;有2例(6.45%)出现有咳血症状的肺出血,均简单处理观察后自愈。结论CT片加X线透视定位和CT定位胸肺部病灶穿刺活检技术是1种安全、实用、有效的诊断技术方法,对胸部肿瘤性病变的确诊和组织分型有很高的临床应用价值。
OBJECTIVE: To design the percutaneous thoracentesis and biopsy under the guidance of X-ray fluoroscopy and CT laser locating line plus body surface marker positioning method on the CT slice. The design of the puncture protocol and the influence of the puncture success rate, accuracy and complication rate Factors to explore. Methods Totally 7 cases were treated with CT radiography and X-ray fluoroscopy. Twenty-one patients were examined by CT in 31 cases. Thoracic and pulmonary lesions biopsy was performed. Results The puncture success rate was 100%, the diagnostic accuracy was 87.10% (27/31). Complication: The incidence of pneumothorax was 22.58% (7/31). All patients were cured after 1 ~ 4 days. Two cases (6.45%) had pulmonary hemorrhage with hemoptysis. Conclusions CT scanning plus X-ray and CT localization of the lung and lung lesions by biopsy are a safe, practical and effective diagnostic technique, which has high clinical value for the diagnosis and histological classification of thoracic neoplastic lesions.
