【Abstract】 Objective To explore the detecting method for the normal innominate artery (Inn A) and to analyze Inn A imaging characteristics and blood flow index. Methods In accordance with the anatomic feature, the normal Inn A of 136 cases was detected by means of color Doppler ultrasound. The route and internal diameters and blood flow index of Inn A were observed. Results The internal diameters of normal Inn A was (11.2±0.6) mm. The blood flow index of Inn A differs about age. The shape of pulse waves of Inn A looks like common carotid artery. Conclusion The route and internal diameters and blood flow index of Inn A can be clearly demonstrated with color Doppler ultrasound. Color Doppler ultrasound is the first choice for the diagnosis of Inn A.更多还原
