肺穿刺活检肺组织出血和发生气胸相互关系的探讨

目的 探讨肺活检中肺组织出血和发生气胸两者间的关系.资料与方法 选用18G半自动槽式切割活检针,CT定位下经皮经肺穿刺取材进行细胞学、组织学检查.结果 168例中发生气胸63例,占37.5%;肺组织出血76例,占45.2%.肺出血与气胸组发生例数呈明显负相关(P< 0.01);针道周围肺组织出血患者的气胸发生率减少(P<0.05).结论 肺穿刺活检发生针道周围肺组织出血能降低气胸的发生.

Study of Relationship Between Pulmonary Hemorrhage and Pneumothorax after Lung Biopsy

Objective To investigate the relationship between pulmonary hemorrhage and pneumothorax in patients undergoing lung biopsy.Materials and Methods CT guided lung biopsy was performed in 168 patients using 18 Gauge semi-automatic slot cutting biopsy needle.Results Pneumothorax was found in 63 cases(37.5%) after lung biopsy,and pulmonary hemorrhage was seen in 76 cases(45.2%).Pulmonary hemorrhage negatively associated with the presence of pneumothorax(P<0.01).Incidence of pneumothorax decreased in patients with pulmonary hemorrhage after lung biopsy(P<0.05).Conclusion Pulmonary hemorrhage around the biopsy site might decrease the risk of pneumothorax in patients undergoing lung biopsy.
