Abstract: Objective To summarize the clinical characteristics of children with vascular-related hemoptysis, in order to find the risk factors of hemoptysis volume and recurrence. Methods The clinical data of children with vascular-related hemoptysis who received interventional therapy from January 2012 to January 2020 were retrospectively analyzed. According to the hemoptysis volume, children were divided into massive hemoptysis group and non-massive hemoptysis group. According to the clinical outcome, they were divided into relapsed group and non-relapsed group. Logistic multivariate regression analysis was used to analyze the factors affecting the hemoptysis volume and the recurrence of postoperative hemoptysis. Results A total of 41 children (19 boys and 22 girls) with vascular-related hemoptysis were included, and the median age was 8.9 (6.9-11.2) years. Chest vascular enhancement CT showed that abnormal blood vessels were located in the right lung in 32 cases, mainly in the lower lobe of the right lung. Abnormal blood vessels were found in both lungs in 3 cases, in the left lung in 1 case, and no abnormal blood vessels were found in 5 cases. Binary logistic regression analysis showed that large abnormal blood vessel diameter and Mycoplasma pneumoniae (MP) infection were independent risk factors for hemoptysis (P<0.05), while increased abnormal blood vessels were independent risk factors for the recurrence of hemoptysis (P<0.05). Conclusions The high risk factors affecting the hemoptysis volume in children with vascular-related hemoptysis are abnormal vascular diameter and MP infection. Interventional occlusion of abnormal blood vessels is a safe and effective treatment method, and the number of abnormal blood vessels is an important predictor of postoperative recurrence.
