CT引导肺穿刺对肺内〈3cm病灶的活检价值

目的评价CT引导肺穿刺对肺内〈3cm病灶的活检价值。方法回顾性分析CT引导下肺部病变穿刺活检213例，均有手术病理和临床随访资料证实。按病灶大小分为两组，其中≥3cm者136例，为大病灶组；〈3cm者77例，为小病灶组。比较两组病例的诊断准确率及并发症发生率。结果CT引导肺穿刺活检对大病灶组、小病灶组的诊断准确率分别为83．09％和84．42％，P〉0．05。气胸发生率为3．68％和15．58％，出血发生率为6．62％和24．68％，P均〈0．05，小病灶组气胸及出血发生率高于大病灶组。结论CT引导肺穿刺活检对于肺内〈3cm病灶的诊断准确率与≥3cm的病灶组相近；小病灶组的并发症发生率高于大病灶组，但无严重并发症，安全性较好。

The value of CT-guided percutaneous lung biopsy for pulmonary lesions less than 3 cm in diameter

Objective To evaluate the value of CT-guided percutaneous lung biopsy for pulmonary lesions less than 3.0cm in diameter. Methods A retrospective analysis of CT-guided percutaneous lung biopsy was performed in 213 patients, all of which had been verified by surgical pathology or clinical follow-up, in 213 lesions, 136 lesions were greater than or equal to 3cm in diameter and 77 lesions were less than 3cm in diameter. The diagnostic accuracy and complications rate in two groups were compared with each other. Results The diagnostic accuracy of CT-guided pereutaneous lung biopsy for the greater than or equal to 3 cm in diameter lesions and the less than 3 em in diameter lesions were 83.09% and 84.42% , P 〉 0.05. The pneumothorax rate of them were 3.68% and 15.58% , the bleeding rate of them were 6.62% and 24.68% , P 〈0.05 ; which had significant difference between these two groups. Conclusions The diagnostic accuracy of CT-guided pereutaneous lung biopsy were similar in two groups. The complications rate of less than 3 em in diameter lesions was higher than that of large lesions. It is a safety inspection method without serious complications.
