Interventional radiology of Bronchial artery embolization due to massive hemoptysis

Abstract

Hemoptysis which is comparatively common symptom in respiratory disease patients is a clinical symptom which has high risk of death in spite of many curative means. Bronchial tube embolization is a very useful medical procedure when hemoptysis does not stop for treatment of internal medicine or surgery and in addition to the purpose of instant hemostasis, for patients for whom surgical operation is impossible or for the purpose of gaining time to improve the state of the patient before surgical operation. In relation to this, this study is to know of the usefulness of bronchial tube artery embolization. The objects were 60 persons for whom bronchial tube artery embolizations are conducted because of large hemoptysis occurred from March 2007 to December 2009 in J hospital. They had large hemoptysis of 400ml or more per day and 200ml or more at a time or though the quantity of hemoptysis was less than 400ml they did not respond to the treatment of internal medicine for 10 days or longer. The average age was 60.5 years and cause diseases were tuberculosis, bronchiectasis, and pneumonia and lung cancer. Embolus parts were Rt bronchial artery 19 examples, Lt bronchial artery, both bronchial artery, Rt Intercostobronchial artery, and they were the case where embolization for many blood vessels were simultaneously carried out. As embolus materials, PVA (conteour) and microcoil were used. In 76.6% of 60 persons of patients hemorrhage stopped with the lapse of time after the procedure and in 4 examples (6.6) re-embolization was carried out due to re-bleeding after the procedure. Bronchial tube artery embolization has high early success rate and effectively controls hemoptysis in the treatment of hemoptysis and is an effective emergency remedy for hemorrhage due to large hemoptysis and will be a good medical procedure which reduces death rate. In addition, primarily if it is conducted together with the treatment of internal medicine it will be, as an effective curative means for hemorrhage due to large hemoptysis, a good mediate radial rays medical procedure which reduces death rate.
