ABSTRACT

Objective To discuss the application of different types of bronchial arteriography catheter in performing bronchial artery embolization (BAE) for the treatment of hemoptysis.Methods The clinical data of a total of 97 patients with hemoptysis,who received BAE during the period from January 2013 to May 2016,were collected.According to angiographic findings in aspect of the opening and running direction of the arteries causing bleeding,the responsible arteries were divided into 4 types:upward opening,horizontal opening and running upwards,horizontal opening and running downwards,and downward opening.For each responsible artery,appropriate angiography catheter was selected from the following catheters:MIK catheter,left gastric artery catheter,Cobra catheter,Simmon-1 catheter and Simmon-2 catheter.With super-selective catheterization technique the selected suitable catheter was inserted into the responsible artery and angiography was subsequently performed.The effect of the selection of bronchial arteriography catheter in performing BAE for hemoptysis was analyzed.Results A total of 180 responsible arteries were detected in 97 patients.Of the 180 responsible arteries,artery with upward opening was seen in 42,artery with horizontal opening and running upwards was found in 54,artery with horizontal opening and running downwards was observed in 46,and artery with downward opening was detected in 38.The success rates of super-selective catheterization for MIK catheter,left gastric artery catheter,Cobra catheter and Simmon catheter were 83.3％ (35/42),92.6％ (50/54),87.0％ (40/46) and 89.5％ (34/38,including 30 Simmon-1 catheters and 4 Simmon-2 catheters) respectively.After BAE,the responsible arteries were occluded in all patients,and hemoptysis stopped immediately.The recurrence rate at 6 months after BAE was 7.2％ (7/97).Conclusion For the treatment of hemoptysis,BAE is safe and effective.The key point to ensure a successful BAE is that the selection of appropriate catheter should be based on the opening and running direction of the artery causing bleeding.
