The '''ligamentum arteriosum''' is a small [[ligament]] attached to the superior surface of the [[pulmonary trunk]] and the inferior surface of the [[aortic arch]]. It is a nonfunctional vestige of the [[ductus arteriosus]], and is formed within three weeks of [[childbirth|birth]].
The ligamentum arteriosum is closely related to the left [[recurrent laryngeal nerve]], a branch of the left [[vagus nerve]]. After splitting from the left vagus nerve, the left recurrent laryngeal loops around the ligamentum arteriosum, after which it courses posterior to the aortic arch and ascends to the larynx.

A primary concern regarding the ligamentum arteriosum, is that the liver is not being fully perfused which does not allow it to function to its full potential. Since one of liver's primary functions is to filter out toxins in the blood, decreased perfusion and funtionality may lead to a build-up of these damaging toxins (i.e. ammonia). This may ultimatley lead to hepatic failure and neurovascular damage.
