Abstract:
Objective:To observe the clinical features ofblood supply arterial of non-small cell lung cancer(NSCLC)by the multi-slice spiral CT angiography(MSCTA).Methods:92 patients with confirmed NSCLC conducted blood supply arterial examination by the MSCTA,38 patients with chronic lung inflammation of the same period as control group.Two experienced physicians analyzed the results though double-blind method.Results:In 92 NSCLC patients,only 78 patients(84.8%)supplied by the bronchial arteries;9 patients (9.8%)supplied by he extra-pulmonary arterial;5 patients(5.4%)supplied by mixed blood vessels.MSCTA performance for all the tumor feeding artery were distorted,and tumor area showed chaotic vascular shadow.And chronic lung inflammation were easier to have extra-pulmonary circulation arterial blood supply compared with NSCLC(?2=14.981,P=0.000 1),the rates were 47.4%and 15.2%, respectively;the number of blood supply arteries in patients with chronic lung inflammation and NSCLC were quite(t=1.542,P=0.126); but the blood supply artery diameter in patients with chronic inflammation significantly thicker than that of the NSCLC group(t=5.805, P=0.000 1).And,MSCTA also showed that vascular often coincide with each other to form a broad network in chronic lung inflammatory group.Conclusion:The multi-slice spiral CT angiography have a good identification for non-small cell lung cancer arterial blood supply, which can provide the basis for their interventional therapy;and,the blood supply arteries become more evident,more to stimulate the outside pulmonary arterial in chronic lung inflammation,so that,it can provide references for non-small cell lung cancer differential diagnosis.
