Abstract:
Objective To evaluate the clinical application of CTA in the bronchial artery embolization treatment.Methods TwentyGeight patients undergoing bronchial artery embolization treatment were divided into two groups.Patients with the examination of bronchial artery CTA before interventional treatment were in group A,others in group B.In group A,according to the distribution of the bronchial artery shown by the CTA,the appropriate catheter was selected for the bronchial artery angiography and embolization.In group B,various catheters for the bronchial artery angiography were performed to find the responsible blood vessels for embolization.The total therapeutic effect, operation time,DSA exposure time and contrast agent were compared between the two groups.Results The pretreatment CTA and DSA contrast were compared and the consistency of the bronchial artery was 90.9%.The effective efficiency of group A was 100%, and the effective rate of group B was 83.3 3%.The time of operation was (6 6.9 ± 1 4.5 )min in group A and (1 3 3.5 ± 1 9.4)min in group B,respectively.DSA exposure time was (2 7.9 ± 1 3.8)min and (5 5.1 ± 1 7.2 )min respectively,and the contrast agent dosage was (89.7±1 7.1)mL and (235.1±1 6.6)mL respectively.The differences between the two groups were statistically significant (P＜0.0 1).Conclusion The bronchial artery CTA examination before interventional treatment is an advantage in increasing the success rate,saving time,and improving efficacy.
