Abstract Background A wide variety of congenital thoracic aortic variants and pathological anomalies could be assessed recently in diagnostic and interventional radiology. Multi-detector computed tomography (MDCT) is one of the most important non-invasive diagnostic tools for their detection. The aim of the study was to evaluate role of MDCT scanning for diagnosis of thoracic aortic anatomic variants and diseases in pediatric patients. Results Thirty patients (15 male and 15 female), mean age (8.49 ± 20.29 months) were diagnosed with different thoracic aortic anomalies by MDCT then confirmed by surgical results. MDCT was more sensitive than echocardiography in detection of hypo plastic arch, vascular rings, interrupted aortic arch anomalies, and aortic coarctation. Both MDCT and echocardiography showed 100% sensitivity in their detection of TGA, TOF, and PDA. MDCT detected 6 cases of right-sided aortic arch while echo missed 2 cases. Different aortic arch branching patterns and coronary origin were better demonstrated by MDCT. Conclusion 320-Multi-detector computed tomography is a reliable tool for optimal detection of thoracic aortic anomalies and preoperative planning.

Arterial Trunk

AbstractTo assess the prevalence and role of the arterial duct in hearts with incomplete development of the aorticopulmonary septum, 110 autopsy specimens, comprising 100 examples of common arterial trunk and 10 cases with aorticopulmonary window, were studied. In addition to intracardiac malformations, these specimens were analyzed to determine the side of the aortic arch, the presence and location of any interruption of the arch, the presence of any anomaly of origin and course of the subclavian arteries, and the status of the arterial duct. The arterial duct was present in 33 cases, absent in 63 cases and undetermined in four cases with common arterial trunk. The duct provided an essential pathway for flow in the 20 cases with interrupted aortic arch, and in two cases with interruption of the proximal portion of the left pulmonary artery. The presence of the duct in 11 cases, in functional terms, was not essential. In the 10 hearts with aorticopulmonary window, the duct was present in eight. It was an obligatory part of the circulatory pathways in three cases where the aortic arch was interrupted. The prevalence of non-obligatory ducts was 71% in hearts with aorticopulmonary window compared to 15% in hearts with common arterial trunk. The prevalence of the duct in cases with aorticopulmonary window suggests this lesion is a later developmental defect. The functional role of an arterial duct in these hearts should be properly assessed in the clinical situation.

The aim of the study was to evaluate the role of virtual bronchoscopy (VB) in traumatic rupture of the main bronchus Material and methods. Тhe data of virtual bronchoscopy of multispiral computed tomography (MSCT) with multiplanar and 3D reconstructions of 10 patients with traumatic separation of the main bronchus were analyzed. MSCT was carried out by the computer tomograph AquilionONE (320-slice) according to the previously described technique. Results of the study. VB MSCT allowed to determine the presence of a complete or partial rupture of the main bronchus, its distance to the bifurcation of the trachea, the state of the collapsed lung, the presence of fluid in the hemithorax, secondary changes in the bone structures of the chest. The World Bank played an important role in monitoring the adequacy of reconstructive measures on the damaged bronchus, excluding the occurrence of postoperative stenosis. The conclusion. Virtual bronchoscopy of multispiral computed tomography with the capabilities of multiplanar and volumetric reconstructions, postprocessing image processing is an optimal non-invasive method for determining the traumatic lesion of the main bronchi and monitoring the success of the reconstructive surgical manual.

AimEchocardiography is the modality of choice for the diagnosis and serial follow-up of aortic arch pathology. In this article, we review the types of obstruction of the aortic arch, various classification schemes of coarctation of the aorta and interrupted aortic arch, methodology for optimal echocardiographic imaging of the aortic arch, and key echocardiographic measurements for accurate diagnosis of obstruction and hypoplasia of the aortic arch. Finally, we will discuss the limitations of echocardiography in optimal imaging of the aortic arch and the use of other non-invasive imaging modalities such as CT or MRI to provide additional information in these cases.BackgroundCoarctation of the aorta is the more common lesion of the two, with an estimated incidence of four in every 10,000 live births in the United States of America. Interrupted aortic arch is rarer, with an incidence of 19 per one million live births.1 There is a spectrum of pathology of obstruction of the aortic arch, ranging from coarctation of the aorta with and without hypoplasia of the arch to interrupted aortic arch. Both these lesions are frequently encountered in congenital cardiology practice, and will be discussed in the remainder of this article. Obstruction of the aortic arch in the setting of hypoplastic left heart structures or atresia of the aortic valve is beyond the scope of this review and will not be discussed further.
