“…We found diverse types of VR on DSCT, the most common type being the right aortic arch with ALSA and PA sling. These results were different from other reports that consider DAA and RAA with ALSA and left ductus arteriosus to be the most common forms of VR 3 , 16 . We hypothesized that this difference may be due to the fact that the patients were selected with complications that caused by other cardiovascular malformations, as aortic arch anomalies also can be associated with structural CHD.…”

“…Especially in pediatrics, the trachea is particularly vulnerable to extrinsic and results in long-term respiratory problems. As shown in our study, recurrent infections (85.7%), cyanosis (69.4%), and dyspnea (30.6%) were the most common symptoms, and several symptoms often occurred simultaneously, which differed from those of isolated VR 15 , 16 , indicated that the VR associated with CHD may cause more serious and complex symptoms. In addition, greater tracheal compression was found with DSCT imaging when more severe symptoms were present ( r = 0.84), the result suggested that in the presence of severe respiratory symptoms, accurate tracheal compression evaluation is essential.…”

Clinically, early diagnosis and treatment is important for survival of pediatric with vascular ring (VR) associated with congenital heart disease (CHD), and accurate evaluation of VR is a prerequisite for repair surgical. The study aimed to assess the quantitative characteristics of tracheal compression in pediatrics with VR and CHD using dual-source computed tomography (DSCT), and further provided effective information for surgical decisions. A total of 49 VR patients with CHD and 56 controls were enrolled. The tracheal quantitative measurements (short diameter, long diameter, tracheal area and tracheal length) were obtained, and the degree of tracheal compression was assessed. Our results indicated that VR associated with CHD may cause more serious and complex symptoms, and the greater tracheal compression were found on DSCT when more severe symptoms were present (r = 0.84). The degree of tracheal compression was significantly different within the VR group between those with and without surgery (P = 0.002). Finally, there were good agreement among (1-long diameter ratio), (1-short diameter ratio) and (1-area ratio) in patients and controls, respectively. This study indicated that DSCT enables provides accurate quantitative tracheal compression information for VR pediatrics associated with CHD, and evaluation of the degree of tracheal compression by 1-area ratio may contribute to the repair surgical of VR.

“…PAS is an under‐recognized condition that presents with nonspecific symptoms such as dyspnea, cough, and recurrent infections. PAS usually presents within the first weeks to months of life . and the discovery of PAS in adulthood is rare; only a few cases have been previously documented (Table ).…”
