The hemoptysis bronchial arteriography characteristics and analysis of the clinical efficacy of transcatheter embolization

Objective: To analyze massive hemoptysis bronchial arteriography change and evaluate immediately and long-term clinical efficacy of bronchial artery embolization for massive hemoptysis.Methods: 32 cases of medical refractory hemoptysis were performed bronchial artery embolization.Thoracic aortic angiography and selective bronchial arteriography was performed before the procedure in order to evaluate the characteristic of the feeding artery.Embolism materials was used a combination of gelatin sponge and PVA(polyvinyl alcohol particles) particles.The clinical data and imaging findings were retrospectively analyzed.Results: Bronchial arteriography performance: bronchial artery thickening,tortuosity(100%),arterio-venous fistula(41%),pseudoaneurysms(15%),contrast agent extravasation(22%).Four cases of non-bronchial artery(3 cases intercostal artery,1 case of internal mammary artery) is involved.1-2 weeks after embolization observed immediate hemostasis effect,31 cases(97%) patients with hemoptysis stop,no reduction of one cases.The review imaging showed intercostal artery angiography were seen in lesions blood supply.After performed intercostal artery embolization,hemoptysis were significantly reduced.No obvious complications and adverse reactions were observed.0ne patient early recurrence after one month.The remaining 30 patients,postoperative follow-up observation 6-24 months.Recurrent hemoptysis 8 cases,the recurrence rate was 29%,Percutaneous bronchial artery embolization successful hemostasis in 3 cases.Conclusion: Bronchial arteriography of hemoptysis much performance for bronchial artery vascular abnormalities,non-bronchial arterial bleeding may.Percutaneous bronchial artery embolization for the treatment of refractory massive hemoptysis is safe and effective.Use a combination of embolism materials can guarantee embolization effect.
