1 Transthoracic Echocardiography Evaluation of Left Cervical Aortic Arch with Aneurysm Formation 
Victor Chien-Chia Wu, Wei-Ting Chen, Chao-Yung Wang, Chun-Chi Chen, Jaw-Ji Chu, Fen-Chiung Lin  Journal of Medical Ultrasound  Volume 20, Issue 3, Pages (September 2012) DOI: /j.jmu Copyright © Terms and Conditions

2 Fig. 1 Chest radiography with (A) P-A and (B) lateral views. Note the bulging and widening of superior mediastinum (arrows). Journal of Medical Ultrasound  , DOI: ( /j.jmu ) Copyright © Terms and Conditions

3 Fig. 2 Echocardiography with suprasternal approach. (A) Normal compared to (B) the aneurysmal dilatation at the distal end of aortic arch. Note the aortic arch (*), left common carotid artery (arrow), and right pulmonary artery (arrowhead). Journal of Medical Ultrasound  , DOI: ( /j.jmu ) Copyright © Terms and Conditions

4 Fig. 3 (A) Color Doppler echocardiography showed color flow jet inside the lumen of the tortuous aortic arch. (B) Pulse-wave (PW) Doppler interrogation showed color flow directing toward the transducer with jet velocity 1.75 m/s. (C) PW Doppler showed color flow directing away from the transducer with jet velocity 2.25 m/s. The increased velocities suggested pseudocoarctation with maximum pressure gradient of 20.25 mmHg at distal aortic arch.

5 Fig. 4 Computed tomography showed cervical aortic arch with aneurysm formation at different angles. Note the proximal end of aneurysm formed between left common carotid artery (LCCA) and left subclavian artery (LSA). RIA = right innominate artery.
