Clinical Application of 128-slice Spiral CT Bronchial Arteriography in Diagnosis of the Central Type of Lung Cancer

Objective To observe the clinical value of 128-slice spiral CT bronchial artery angiography in diagnosing central lung cancer.Methods A total of Sixty patients with central or septal lung cancer admitted from May 2015 to May 2017 in our hospital were prospectively studied.All patients underwent CT angiogra phy with 128-slice spiral CT and bronchial artery DSA as control.The bronchial artery display and bronchial artery detection of different diameter cases of CTA and DSA were compared.Results A total of 46 patients were diagnosed with a single bronchial artery,and 14 patients with two bronchial arteries by CTA in 60 patients,a total of 74 bronchial arteries were detected;A total of 39 patients were diagnosed with single bronchial artery,and 21 patients with two bronchial arteries by DSA in 60 patients,a total of 81 bronchial a rteries were detected.The detection rate of bronchial artery branches was 91.36%(74/81) in CTA,which was not significantly different from DSA(P> 0.05).The diameter of74 bronchial arteries detected by CTA ranged from 0.92 to 7.94 mm,with an average of(2.34±0.84)mm.The diameter of bronchial artery detected by DSA ranged from 0.61 to 7.85 mm(2.26±0.63)mm,with no statistical difference significance(t=0.674,P=0.501).In terms of diameter distribution,the distribution of BA diameter more than 1 mm in CTA was completely consistent with DSA.Only seven bronchial a rteries missed ≤1 mm were missed,and the diagnostic coincidence rate of diameter distribution was 91.36%(74/81).Conclusion There is a possibility that central pulmonary carcinoma has dual pulmonary artery and bronchial artery blood supply.Compared with DSA,CTA has a good indication of BA in central lu ng cancer and can simultaneously show the presence of pulmona ry artery blood supply,which can provide a more comprehensive observation of tumor blood supply without invasiveness,Fast sca n ning,simple operation,easier for patients to accept,for the clinical treatment of patients with central lung cancer to provide a reliable basis for the image,it is worth promoting.
