Abstract：Objective To explore the curative effect of emergency transcatheter arterial embolization (ETAE) in patients with massive hemoptysis caused by pulmonary‐vascular abnormalities .Methods 38 cases of massive hemoptysis caused by pulmonary‐vascular abnormalities underwent emergency arteriography .After bleeding arteries were located ,the patients were given embolotherapy with tricacryl gelatin microphere (TAGM ) and gelfoam strips .The arteriography manifesta‐tions and therapeutic outcome of all 38 patients were retrospectively analysed .Results 52 bleeding arteries were located and embolized successfully in 38 patients .22 patients were diagnosed with bronchial artery‐pulmonary artery fistul ;8 pa‐tients were diagnosed with intercostal artery‐pulmonary artery fistul ;4 patients were diagnosed with thyrocervical trunk‐pulmonary artery fistul ;Bronchial artery‐pulmonary vein fistul and intercostal artery‐pulmonary vein fistul were diagnosed both two case .Pulmonary lobectomy was performed in 7 patients after hemostasis of embolotherapy .After 12‐month fol‐low‐up ,all patients had no recurrence haemoptysis after the embolotherapy .Conclusion ETAE is a small trauma ,safety and efficacy treatment for the massive hemoptysis caused by pulmonary‐vascular abnormalities .The precondition of suc‐cessful treatment is to know the polyphyly of haemoptysis disease blood vessels and the complexity of blood supply .The key of successful treatment is to completely embolize all blood supply arteries .
