“…Additionally, the spatial resolution of CT is better compared to MRI and therefore, provides greater detail when it comes to anatomical analysis of the arterial and venous structures surrounding the heart. On the other hand, MRI scan is more useful for functional evaluations of the heart and detecting intracardiac malformations as well as cardiac wall abnormalities ( 9 ). In our experience, accurate pre-operative echocardiographic detection of this vascular anomaly has enhanced planning and decision-making for pediatric cardiologists and cardiac surgeons, without need for a CT or an MRI scan.…”

Tetralogy of Fallot With Right Aortic Arch and Retro-Aortic Innominate Vein

Right aortic arch (RAA) and retro-aortic innominate vein are rare vascular anomalies. Diagnosis of these anatomical variations can be achieved using fetal echocardiography, post-natal echocardiography, and computed tomography scan. RAA can form a vascular ring when associated with other vascular anomalies which may compress the trachea and/or esophagus. On the other hand, the existence of retro-aortic innominate vein can influence the clinical decision-making and surgical strategy. We report a rare occurrence of both RAA and retro-aortic innominate vein in a 3 months old girl with a prenatal diagnosis of tetralogy of Fallot and include details of her presentation and successful management.

“…3 Diagnosis can usually be made by transthoracic ultrasonography, and is enhanced by saline contrast transthoracic or transesophageal echocardiography. [11][12][13]18,19,[21][22][23][24][25] The ultrasound "window" may be of poor quality in cases of thymic hypoplasia or agenesis. 14 Visualization of the frontal section of the aortic arch allows recognition of the entire course of left brachiocephalic vein.…”

The present perspective is a synthesis of 80 published investigations in the setting of a retroaortic left brachiocephalic vein, described in 250 patients. Clinical presentation, radiographic findings, ultrasonographic findings, saline contrast echocardiography, computed-tomographic angiocardiography, magnetic resonance imaging, and angiocardiography provided the diagnostic information used to define the disease entity prior to considering the surgical approach to the associated cardiac anomalies. We have also addressed several issues concerning the influence of isomerism, the establishment of diagnosis, and its importance in various surgical and interventional procedures. Although the retroaortic left brachiocephalic vein is asymptomatic, its recognition during clinical investigation should raise the possibility of an association with other malformations, especially right aortic arch, ventricular septal defect, and anomalies of the outflow tracts. We submit that an increased appreciation of this venous anomaly may facilitate surgical planning, endovascular procedures, placement of central venous lines, and transvenous pacemakers.

“…Due to the heterogeneous recommendations and lack of large comparative studies 14 , three different chest CT CA injection protocols were in use within the last decade since 320-slice volume CT was introduced in our institution (tertiary pediatric center). The primary protocol in the first years of the study period used a common bolus tracking technique with undiluted CA followed by saline flush 15–17 , frequently resulting in unsatisfying image quality due to excessive vessel enhancement.…”

To obtain the highest diagnostic information with least side effects when performing thoracic CT angiography (CTA) is challenging in young children. The current study aims to compare three contrast agent (CA) injection protocols regarding image quality and CA characteristic: a standard CTA, a fixed-bolus delay protocol, and the “microbolus technique (MBT)” developed in our institution. Seventy chest CTA scans of patients (<2 years) were divided into three groups. MBT was applied in group I, the standard protocol in group II and a fixed bolus delay in group III. Objective image quality was assessed by measuring peak enhancement, image noise, signal-to-noise (SNR) and contrast-to-noise ratios (CNR). Two observers scored subjective image quality and artifacts. Significantly lower amounts of CA (mean ± SD) were used in the MBT group compared to Group II (9.0 ± 3.7 ml vs. 12.9 ± 4.5 ml). A lower, but still diagnostic (>400 HU) enhancement was registered in all major thoracic vessels in group I without significant differences regarding SNR and CNR in most regions (p < 0.05). The best scores for image quality and artifacts were reached in group I. All three chest CTA contrast injection protocols offered diagnostic vessel enhancement in young patients. MBT was associated with reduced image artifacts and less injected CA.
