a E u s a o 6-year-old boy was referred for follow-up of a ventricular septal defect, which was first diagnosed when he was a neonate. Cardiac catheterization performed t 7 months of age revealed an aberrant left subclavian artery rising from the right aortic arch. Recurrent respiratory inection that caused stridor and/or wheezing occurred in early nfanthood, but it was deemed not related to th...

An 18-year-old male patient was referred with an atypical form of vascular ring consisting of a right aortic arch, a right descending aorta, a persistent right ligamentum arteriosum, and a dilated right pulmonary artery in the setting of discontinuous pulmonary arteries with a single functional right lung. The initial presentation was that of pneumonia of the right lung and later evaluation rev...

Stridor beginning at, or soon after, birth is not an uncommon symptom Such stridor is seldom severe, has a natural tendency to become progressively less marked, and in the majority of infants disappears entirely at the end of the first, or early in the second, year of life. Occasionally, some cause of laryngeal or tracheal obstruction is found and can, where possible and when necessary, be elim...

In this case report, we present an infant who has a double aortic arch vascular ring anomaly. We emphasize the importance of maintaining a high level of clinical suspicion for vascular ring when evaluating an infant with the symptom of persistent stridor. Recognizing persistent stridor early and treating the underlying cause can, indeed, optimize outcomes. Case A 3-day-old boy presented to the ...

OBJECTIVE To improve the surgical results of aortic dissection, we used a novel vascular ring connector for anastomosis. METHODS The vascular ring connector is a titanic ring used as a stent in the vascular graft to achieve a quick, blood-sealed, and sutureless anastomosis. From November 2007 to December 2008, 19 consecutive patients (age range 36-77 years; 16 male and 3 female) with aortic d...

Many conventional technologies for fabricating tissue engineering scaffolds are not suitable for fabricating scaffolds with patient-specific attributes. For example, many conventional technologies for fabricating tissue engineering scaffolds do not provide control over overall scaffold geometry or over cell position within the scaffold. In this study, the use of computer-aided laser micromachin...

INTRODUCTION Both patent ductus arteriosus (PDA) and vascular rings often require surgical treatment to prevent complications and alleviate symptoms, respectively. Management in infants and children has traditionally required an open thoracotomy. However, given the known advantages of the thoracoscopic approach, increased technical experience, and improved instrumentation, the minimally invasiv...

Double aortic arch with an atretic left arch distal to the origin of left subclavian artery was diagnosed with multi-detector row computed tomography (MDCT) in two children with dysphagia. This rare type of complete vascular ring is clinically important because it may be confused with right aortic arch in mirror imaging. Anatomic details of this rare type of complete vascular ring demonstrated ...

We report a case of a 750 grams premature female who was scheduled for surgical ligation of a patent arterial duct. Intra-operative findings showed a patent arterial duct in association to a retro-esophageal aortic arch creating a complete vascular ring around the trachea, which was successfully divided. A vascular ring should be ruled-out in premature infants prior to ductal ligation at bidime...

A case of an 11-months-old girl with vomiting and laryngeal stridor is presented, and in whom a Kommerell diverticulum was demonstrated, which is a rare variant of the incomplete vascular ring. It is well known that the magnetic resonance is the best study to define this malformation. In this patient, it was the cardiac catheterization which allowed to define the structures that constituted the...
