Abstract：Objective To explore the comparative study of the anatomical variation of bronchial artery system Uygur and Han races by muti-slice spiral CT angiography(CTA).Methods Retrospective analysis was performed on 70 cases of Uygur and 70 cases of Han patients with hemoptysis by MSCT from January 2016 to December 2017 in the First People's Hospital of Kashgar Region. The bronchial artery anatomical relationship of the bronchial artery in patients with hemoptysis was displayed and observed using post-processing techniques such as multi-plane recombination (MPR), maximum density projection (MIP) and three-dimensional volume reconstruction (VR).The origin, opening position, distribution type and typing of bronchial artery (BA) in two groups of hemoptysis patients were displayed and observed.Results A total of 371 bronchial arteries, 208(56.06%) in situ and 163(43.94%) in ectopic were observed in 140 patients with CTA.Among them, 70 cases of orthotopic bronchial arteries of Uygur showed a total of 90 branches, with ectopic 87/177(49.16%) branches, 70 cases of orthotopic bronchial arteries of Han showed 118 branches, with ectopic 76/194(39.18%) branches. There were no statistically significant differences between the two groups (χ2=3.740, P＞0.05). The heterotopic bronchial artery originated from the aortic arch and the intercostal artery was different between the two groups(χ2=9.861, 4.415, all P values＜0.05). There were statistically significant differences between the two groups in the location of the anterior, posterior, left and right walls of the descending aorta(χ2=19.763, P＜0.01). Type Ⅱ was also the most common type of bronchial artery development in both groups, with 66 branches in Uygur (49.63%, 66/133) and 74 branches in Han (55.64%, 74/133), followed by type Ⅰ (27.07%, 36/133) and type Ⅳ (14.28%, 19/133) in Uygur, and type Ⅰ (19.54%, 26/133) and type Ⅲ(19.54%, 26/133) in Han. There were significant differences between two groups(χ2=12.766, P＜0.01).Conclusions There are great differences between the Uygur and Han patients with hemoptysis in the origin of bronchial artery, location of wall opening and its developmental type. Bronchial artery CTA performed before bronchial artery embolization can provide detailed three-dimensional anatomical information for interventional therapy, which has great clinical significance for the rapid selection of responsible vessels and the avoidance of repeated intubation to shorten the angiography time.
