CT引导下经皮肺穿刺活检45例分析(1)
【摘要】 目的 探讨CT引导下经皮肺穿刺活检术的临床应用价值及其安全性。方法 对45例CT引导下经皮肺穿刺活检获取肺内病变部位病理标本和安全性进行回顾性分析。结果 45例均穿刺成功100%(45/45)。对肺部恶性病变病理诊断正确率92.3%(36/39),良性病变诊断准确率83.3%(5/6)。10例发生气胸,其中1例行胸腔闭式引流术,其余气胸量小,自行吸收。3例发生小量咯血,给予止血药物观察,未见大咯血。6例活检部位有疼痛感,未行处理,症状于1～3 h后消失。结论 CT引导下对肺内病变穿刺活检是一种相对安全,准确性高,对肺部病变定性诊断有重要意义,穿刺对患者有一定创伤,所照射剂量较大要严格选择穿刺适应证,掌握穿刺技巧,重视并发症的预防。【关键词】 计算机体层摄影;穿刺活检;CT引导; 并发症 【Abstract】 Objective To observe the clinical application and safety of lung puncture biopsy per cutem guided by CT. Methods 45 patients were selected,patho specimen from these lung diseased region and the safety of this method were analysis retrospectively. Results 45 examples puncture were performed successfully,100%(45/45).The correct ratio of pathologic diagnosis to m alignant lung disease were 92.3%(36/39),of benign lung disease the ratio were 83.3%(5/6),pneumatothorax take place at 10 patients,of the total 1 patient were taken thoracic close drainage,for the rest,the capacity of the pneumatothorax were little,absorbed quickly without any step.3 patients hemoptysis for a short period,by supply with anastaltic,the aymtom disappeard no macro-hemoptysis were found.6 patients feel pain at the point of the position that the biopsy were taken the symptom disappeard after 1 to 3 hours.Conclusion The lung puncture biopsy percutem guided by CT is a utility and relative safe method,its results were punctual,is important meaning to diagnose the lung disease .But the punct is a wound to patients, and the expose dose is a little larger,so select the punct indication strictly,master the skill of punct and prevent the complication. ......
