A Retrospective Analysis of 334 Cases of Hemoptysis Treated by Bronchial Artery Embolization

“…However, increasingly it is used in moderate hemoptysis and recurrent mild hemoptysis that hampers the lifestyle of the patient. 9,10,16,17 The majority of our patients (58.4%) had moderate hemoptysis. Recurrent mild hemoptysis was present in 21% of patients and the rest had severe hemoptysis.…”

“…10 Use of NBCA requires optimal skill and knowledge regarding the concentration of mixture and speed of injection. With NBCA the future recanalization rates are said to be lower, but there is the disadvantage of closure of the main access artery often which may lead to sourcing of vascular supply from other arteries.…”

“…This result is comparable to results of previous studies. [8][9][10][11]18 Repeat procedure within two months was performed in 25 (6.5%) patients due to technical or clinical failure of the procedure. This might be because of failure to identify or embolize bleeding vessels in the first setting or the nature of primary disease not responding to bronchial artery embolization.…”

“…This can be attributed to the increasing use of microcatheters as has been mentioned in recent studies. [8][9][10][11][12][13] With microcatheters, it is now possible to safely deliver the embolization material beyond the origin of the spinal arteries thus preventing this complication. We encountered only minor complications such as non-progressive localized dissection and chest pain.…”

“…The value of BAE in controlling massive hemoptysis is well documented. [8][9][10][11][12][13] In this retrospective analysis we sought to analyze the safety, technical success, and short and long-term outcomes of BAE.…”
