5F TIG导管在主动脉弓下壁开口的支气管动脉栓塞术中的应用.

Objective To investigate the value of 5F TIG multifunctional catheter in bronchial arterial embolization (BAE) with the vagus bronchial artery opening in the inferior wall of the aortic arch. Methods Preoperative bronchial artery CT angiogram of 31 patients who underwent transfemoral artery BAE showed openings of the vagus bronchial arteries in the inferior walls of the aortic-arches. The success rate, fluoroscopy time, operation lime and curative effect of the BAE were compared between the groups using 5F TIG (15) and non-TIG (16) including Corbra, RLG, Simmen, or Yashiro catheters. Results The success rate of BAE in the inferior wall of the aortic arch was 100% in both the TIG and non-TIG groups without significant difference (P>0.05). The average fluoroscopy and operation time in the TIG group was significantly shorter than that in the non-TIG group (P<0.01). Conclusion Use of 5F TIG angiographic catheter for BAE with the vessel opening in the inferior wall of the aortic arch can reduce the number of catheter exchanges, use of consumable materials, operation time, and radiation exposure.
