“…MDCT can replace traditional bronchography or bronchoscopy with a safer less-invasive method. MDCT images can provide valuable information because the entire airway can be viewed [27, 28]. Furthermore, we demonstrated that the segmental emphysematous change in children CHD associated with increased pulmonary blood flow can be evaluated using MDCT and minimum-intensity projection (minIP) imaging (Fig.…”

BackgroundA lots of articles published regarding the usefulness of multidetector-row computed tomography (MDCT) in children with congenital heart disease (CHD) mostly describe that it can be an alternative to the invasive catheterization and angiography. The unique diagnostic features of this imaging modality have been largely ignored or disregarded. We described the pathological conditions that cannot be diagnosed by conventional angiography with cardiac catheterization but can be accurately diagnosed by MDCT.MethodsWe retrospectively reviewed non-ECG-gated MDCT images acquired from 452 children and young adults with CHD between 2005 and 2010 in our institute. In this article, we focused on the diagnostic advantages of MDCT, and indicated five pathological conditions. (1) When Blalock-Taussig shunt total occlusion prevents catheter insertion into the artificial vessel and angiography is ruled out, the peripheral pulmonary artery during the peripheral pulmonary artery can be imaged and diagnosed using MDCT based on blood flow supplied from many small collateral vessels originating from the aorta. (2) The location and protrusion of the device in the vessel after coil embolization to treat patent ductus arteriosus can be accurately visualized by virtual endoscopy using MDCT. (3) Calcification of patches, synthetic blood vessels, and other prostheses that is indistinct on conventional angiograms is clear on MDCT. (4) Simultaneous MDCT observations of the anatomical relationships between arterial and venous systems on the same image can clarify the detail diagnosis for surgical treatment. (5) Compression of the airways by the great vessels and pulmonary segmental emphysematous change can be diagnosed by MDCT.Results and ConclusionsAmong patients with CHD, MDCT is useful not only as a non-invasive alternative to conventional angiography, but also as a tool for specific morphological diagnoses. In the future, it will be necessary to accumulate experience in the recognition of cardiovascular conditions under which MDCT is necessary and to perform as the appropriate examination.

“…Although the reported morbidity of tracheal anomalies in patients without congenital heart disease is only 0.29% [9], the morbidity of tracheobronchial anomalies in patients with congenital heart diseases ranges from 3.74% to 12.85% [9,10]. Kairamkonde et al [11] and Fowler et al [12] have reported that the tracheal bronchus develops during the embryonal stage and hence is often associated with congenital cardiac anomalies of structures that develop during the same embryonic stage of development.…”

“…The 3D images of our patient with PDA showed segmental tracheal stenosis adjacent to the dorsal border of the right main pulmonary artery. Chen et al [9] reported that the incidence of tracheal stenosis in association with right upper-lobe tracheal bronchus was 31%, and the overall incidence of tracheal stenosis in patients with congenital tracheobronchial anomalies was 11.2%. Patients with congenital heart disease with abnormally enlarged vascular structures, due to high pulmonary artery pressure or high left atrial pressure, can develop extrinsic airway compression [13,14].…”

“…Although it is reported that careful preoperative observation of chest X-rays can identify a tracheal bronchus [7,21], the diffi culty in diagnosis arises when the tracheal bronchus overlaps the mediastinal shadow on the chest X-ray, as occurred in our patient. Tracheal bronchus is well diagnosed with chest CT [2,9,10,15,22]. Spiral CT has especially broadened the potential of the imaging of lung anatomy by offering various reformation techniques, including multiplanar reconstruction, 3D reconstruction, shadedsurface display, and virtual bronchoscopy [2].…”

Three-dimensional CT image analysis of a tracheal bronchus in a patient undergoing cardiac surgery with one-lung ventilation

The incidence of a tracheal bronchus--that is, a congenitally abnormal bronchus originating from the trachea or main bronchi--is 0.1%-2%. Serious hypoxia and atelectasis can develop in such patients with intubation and one-lung ventilation. We experienced a remarkable decrease in peripheral oxygen saturation (SpO2) and a rise in airway pressure during placement of a double-lumen endobronchial tube in a patient with patent ductus arteriosus and tracheal bronchus. Substitution of the double-lumen tube with a bronchial blocker tube provided secure isolation of the lung intraoperatively. A type I tracheal bronchus and segmental tracheal stenosis were identified on postoperative three-dimensional (3D) computed tomographic (CT) images. Preoperative examination of chest X-rays, CT images, and preoperative tracheal 3D images should preempt such complications and assist in securing safe and optimal one-lung ventilation.

“…With respect to 3D visualization of the airway tract, Chen et al 9 reported the neonatal tracheobronchial 3D image using CT scan and described the prevalence of airway tract anomalies. Nelson et al 10 first reported the prenatal application of 3D inversion mode to visualize the fetal cardiac structure.…”

The fetal airway tract can be observed using the planes of view in cardiac screening. In three-vessel-tracheal view, the crosssection of the trachea is identified adjacent to the right-posterior side of the middle transverse aorta. In three-vessel view, the cross-section of the right bronchus is observed adjacent to the right side of the ascending aorta. In aortic and ductal arch views, the short axis of the left bronchus is confirmed inward of the arch. In oblique three-vessel view, the right bronchus is seen on top of the ascending aorta coursing toward the azygos vein. To exclude the vessels, absence of blood flow signals in the trachea and bronchi should be reconfirmed by using pulsed and color Doppler imagings. In the whole 'Y-shaped' image, the right main bronchus depicts the more linear extension from the trachea than the left bronchus and the first lobar bronchus that branches near the carina to the right upper lobe. Segmental bronchi also can be depicted in both bilateral bronchi. Several new modalities, including three-dimensional (3D) ultrasound, simultaneous visualization of the fetal trachea and esophagus, and fluid flow waveforms in the fetal airway tract, makes feasible detailed prenatal assessment, prediction of neonatal respiratory condition, and most especially identification of anatomical deformity and pathologic entities.
