P13.07: Fetal aortic arch and its branches anomalies: prenatal ultrasound, vascular cast and gene detection

Fetal sonographic diagnosis of aortic arch anomalies.

Aortic arch anomalies refer to congenital abnormalities of the position or branching pattern, or both of the aortic arch. Although aortic arch anomalies are not uncommon, reports on their prenatal diagnosis are scarce. Insight into the hypothetical arch model is crucial to understanding anomalies of the aortic arch in the fetus. Recognition of the trachea, three major vessels, ductus arteriosus...

Prenatal Ultrasound to Detect Fetal Anomalies

Aortic arch anomalies.

Magnetic resonance imaging has become the gold standard for imaging the aortic arch with the ability to demonstrate not only the arterial branching pattern, but also the relationship of aorta and its branches to the trachea and bronchi. Examples of four major aortic arch types--left aortic arch, right aortic arch, double aortic arch and persistent fifth aortic--with most of their variations are...

Prenatal diagnosis of right aortic arch by fetal echocardiography.

*Corresponding author. E-mail address: [email protected] (F. Silva). Right aortic arch is a cardiovascular malformation or a variant of normality which can be diagnosed by prenatal ultrasound. This malformation may be associated with DiGeorge syndrome (arising from defects in chromosome 22) and can result in posterior compression of the trachea and esophagus, leading to dysphagia and res...

Aortic Arch Anomalies: Simplified Classification

Between the years 1965 and 1970, ten patients were operated on for congenital anomalies of the aortic arch which caused symptoms of tracheoesophageal compression. The classic Edwards' diagram was modified for a more simple mterpretation of these anomalies. Accordingly, all our patients were found to belong to four distinct variations: 1) double aortic arch, which was divided in twosubgroups, a)...
