Abstract:
Objective To investigate the efficacy and safety of blank microspheres combined with microcoils in treating hemopty-sis due to arteriae bronchiales(BA)malformation during bronchial arterial embolization(BAE).Methods A retrospective analysis was conducted on the preoperative data,embolization materials,technical success rate,clinical success rate,postoperative recurrence rate,and complications of 87 patients who underwent BAE using blank microspheres for hemoptysis due to BA malformation.Results There were 87 patients in this study,and BA computed tomography angiography(CTA)classification was as follows:32 cases(36.78％)of type Ⅰ,23 cases(26.44％)of type Ⅱ,19 cases(21.84％)of type Ⅲ,and 13 cases(14.94％)of other types(Ⅳ-Ⅸ).A total of 171 blood vessels were embolized in 87 patients,including 16 ectopic BA,and 130 embolized microspheres,including 104 microspheres of 500-700 μm and 26 of 700-900 μm.There were 265 microcoils,with a technical success rate of 100％,a 24 h clinical success rate of 100％,and a 30 d clinical success rate of 98.85％.The recurrence rate was 3.45％ at 6 months,5.75％ at 12 months,and 8.05％ at 24 months.Postopera-tive complications(Clavien-Dindo classification):complications of grade Ⅰ,embolic syndrome recurrence rate was 8.05％,chest pain incidence was 3.45％,dysphagia incidence was 2.30％,BA injury incidence was 3.45％;complications of grade Ⅳ,paraplegia inci-dence was 1.15％.Conclusion The use of blank microspheres combined with microcoils in the treatment of hemoptysis caused by BA malformation has high safety and clear efficacy.
