Abstract
背景与目的胸腔镜术中对于直径 < 1 cm的肺小结节较难准确定位。数年前即有学者开始尝试使用各种方法进行术前的肺小结节定位。本文从适应症、结果、并发症三个方面回顾性分析了胸腔镜术前CT引导下Hook-wire定位的临床应用价值。方法2010年1月-2010年4月,20例患者于胸腔镜术前接受了CT引导下肺小结节Hook-wire定位。小结节直径从0.5 cm-2 cm(平均9.8 cm±5.3 cm)。评价指标包括定位成功率,定位相关并发症,中转开胸比率等。结果20例患者中18例定位成功,CT定位花费时间平均为14.5 min,全组无严重并发症发生。结论胸腔镜术前CT引导下肺小结节Hook-wire定位有一定的临床应用价值,可帮助术中精确定位肺小结节位置,并且并发症发生率较低。
