a tear duct.
a ventilation duct
Echocardiography showed normal chamber and vessel relationships, a small patent arterial duct, and an atrial septal defect with bidirectional shunting across the oval fossa.
The arterial duct and the oval foramen were patent.
The patient initially had a patent arterial duct that originated from the under surface of the rightsided aortic arch.
These proteins form a fibrous network which is in continuity from the hilum to the alveolar ducts.
There was a saccular aneurysm of 5 mm diameter in the proximal thoracic descending aorta, two millimeters distal to the patent arterial duct.
Somewhere between 80 to 90% of the blood ejected by the right ventricle goes through the duct into the descending thoracic aorta with minimal resistance.
Rotation of the transducer allowed simultaneous imaging of the ascending and descending aorta and distal part of the arterial duct.
A collateral artery originating from the descending aorta supplied the left lung, while the right pulmonary artery originated from the arterial duct.
