【摘要】：目的:分析支气管动脉-肺循环瘘(体-肺分流)在大咯血患者中的发病率,并探讨体-肺分流形成的原因。方法:回顾性搜集本院494例大咯血患者的病例资料,根据病因分为三组,肺慢性炎症组、肺血管病变组和肺恶性肿瘤组。分析各组CT图像,并计算不同组别的体-肺分流发病率和平均每例患者异常支气管动脉或非支气管动脉的体动脉系统的数目,并进行统计学分析。结果:肺慢性炎症组、肺血管病变组和肺恶性肿瘤组的体-肺分流发生率分别为93.0%、75.0%和11.4%。三组的体-肺分流发病率差异具有统计学意义(P0.001,P0.001,P=0.014)。结论:肺慢性炎症组的体-肺分流发生率最高,提示慢性炎症可能是体-肺分流形成的最重要原因之一。对于大咯血患者,在除外明确的肺血管病变后,临床应重点关注肺慢性炎症的诊断和治疗。
[Abstract]:Objective: to analyze the incidence of bronchoarterial-pulmonary shunt (BAF) in patients with massive hemoptysis and to explore the causes of SBF. Methods: the data of 494 patients with massive hemoptysis were collected retrospectively and divided into three groups according to the etiology: chronic pulmonary inflammation group pulmonary vascular disease group and lung malignant tumor group. The CT images of each group were analyzed and the incidence of body-pulmonary shunt and the average number of abnormal bronchial or non-bronchial artery systems in each group were calculated and statistically analyzed. Results: the incidence of body-pulmonary shunt in chronic inflammation group, pulmonary vascular disease group and malignant lung tumor group was 93.0% and 11.440%, respectively. There was significant difference in the incidence of body-lung shunt among the three groups (P 0.001, P 0. 014). Conclusion: the incidence of body-lung shunt is the highest in chronic pulmonary inflammation group, which suggests that chronic inflammation may be one of the most important reasons for the formation of body-lung shunt. For patients with massive hemoptysis, the diagnosis and treatment of chronic pulmonary inflammation should be focused on after definite pulmonary vascular disease.
