CT导引下胸部病变共轴针法穿刺活检的临床应用

目的评价共轴针法在胸部病变穿刺活检中的临床意义。方法联合应用17G、18G切割针和21G抽吸针、PTC针对139例胸部病变进行CT导引下穿刺活检,病灶直径1.2-7.8cm,其中直径<3cm者32例。结果139个病灶共取材291次。活检总阳性率90.7%(126/139),细胞学阳性率和组织学阳性率分别为61.2%(80/130)和84.8%(117/138)。穿刺后发生气胸11例,轻度咯血6例。结论CT导引下胸部病变的穿刺活检是一种安全、有效的检查方法,影响并发症发生率的原因主要取决于患者的体质状况和穿刺次数,细针抽吸和粗针切割活检联合应用可以提高诊断率。

CT-guided biopsy transthoracic of chest lesions by means of the coxial technique

Objective To evalue the clinical effect of CT-guided biopsy of chest lesions by means of the coaxial technique. Methods 139 cases of chest lesions ranging from 12 to 78 mm were punctured by combined use of fine-needle ,PTC needle and cutting needle, and in which 32 cases were smaller than 30mm in diameter. Results Of these 139 cases, 291 adequate specimens were obtained. Rates of precise diagnosis by combined use of fine-needle aspiration and core biopsy were 90.7% (126/139), respectively, whereas those rates were 61.2% (80430) by fine-needle aspiration alone and 84.8% (117/138) by core biopsy alone, pneumothorax occurred in 11 and emptysis was in 6. Conclusion CT-guided percutaneous transthoracic of chest lesions is a safe and effective method. Factors influencing rate of complications are pulmonary function and the number of punctures. The combined use of fine-needle aspiration and core biopsy can improve the diagnostic ability of CT-guided chest biopsy.
