ZHANG Xiaoqin,ZHAO Tian,RUAN Lei, et al. Anatomical study on the bronchial artery with 320 row dynamic volume CT at high contrast injection rates[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2016, 46(5): 379-382.
Abstract：Objective: To evaluate the normal anatomical features and ectopic origination of the bronchial artery in patients with hemoptysis using 320 row dynamic volume CT (DVCT) at high contrast injection rates. Methods: From June 2014 to Sptember 2015, 173 patients with hemoptysis underwent BA angiography was included. The site of origin and distribution of BAs was then analyzed with transverse, MIP, VR and 3D fusion images. Results: From the 173 studied population, the most frequent type of BAs was II type (1R1L), which account for 37.0%. On the right side, 45.6% of BAs originated from intercostal-bronchial trunk (IBT); On the left side, 61.5% had BA with single origination. 45.1% of the studied population had at least one ectopic BAs. The most frequent sites of origin of ectopic BAs were the initial part of descending aorta, followed by the aortic arch. Conclusion: Even though the great variation and fine-calibrate of BAs, 320 DVCT at high contrast injection rate can preciously depicted the normal sites as well as ectopic origination of BAs, thus providing important anatomical information prior to therapeutic decision making of bronchial arterial embolization (BAE).
