评价超声引导下经皮肺外周病变穿刺活检并发肺出血的危险因素及防治对策

目的 探讨超声引导下经皮肺外周病变穿刺活检并发肺出血的危险因素,并提出针对性防范措施.方法 随机选取2013年2月至2015年4月期间本院收治的单发肺外周病变患者118例,所有患者均接受超声引导下穿刺活检,并对其临床资料进行回顾性分析.结果 病灶血流较丰富组患者其肺出血发生率(17.91％)明显高于不丰富组(4.00％),差异有统计学意义(P＜0.05).结论 病灶血流是否丰富是影响超声引导下经皮肺外周病变穿刺活检并发肺出血的主要因素,通过在穿刺前根据病灶CDFI结果对血管数量及走行进行评估,设计合理穿刺路径可有效提高取材成功率,并降低肺出血发生风险.

Risk factors of pulmonary hemorrhage in ultrasound-guided peripheral pulmonary lesions percutaneous biopsy and prevention countermeasures

Objective To investigate risk factors of pulmonary hemorrhage in ultrasound-guided peripheral pulmonary lesions percutaneous biopsy,and propose specific prevention countermeasures.Methods 1 18 cases of solitary pulmonary peripheral lesions admitted to our hospital from February 2013 to April 2015 were randomly selected.All patients underwent ultrasound-guided biopsy,and clinical data was retrospectively analyzed.Result The incidence of pulmonary hemorrhage in patients with rich blood flow of lesions (17.91％)was significantly higher than that in patients with non-rich blood flow of lesions (4.00％),with statistically significant difference (P＜0.05).Conclusions Whether lesions blood flow rich or not is the main factor of pulmonary hemorrhage in ultrasound-guided peripheral pulmonary lesions percutaneous biopsy;the assessment of the number and trend of blood vessels according to CDFI results of lesions before biopsy,the design of reasonable puncture path can effectively improve coverage success rate,and reduce the risk of pulmonary hemorrhage.
