ligamentum arteriosum

Within 1-3 months, the ductus is obliterated and becomes the ligamentum arteriosum.

Upon closure at birth, it becomes the ligamentum arteriosum.

This becomes the ligamentum arteriosum postnatal as pulmonary circulation begins.

The ductus arteriosus normally closes off within one or two days of birth, leaving behind the ligamentum arteriosum.

The ligamentum arteriosum connects the commencement of the pulmonary artery to the aortic arch.

It contains the ligamentum arteriosum, the recurrent laryngeal nerve, lymph nodes, and fatty tissue.

This ganglion, when present, is situated immediately beneath the arch of the aorta, on the right side of the ligamentum arteriosum.

The left RLN is longer than the right, because it crosses under the arch of the aorta at the ligamentum arteriosum.

The residual scar tissue from the fibrotic remnants of DA, called the ligamentum arteriosum, remains in the normal adult heart.

It is often joined by the ligamentum arteriosum (or patent ductus arteriosus) where it forms the descending aorta.

The ligamentum arteriosum is closely related to the left recurrent laryngeal nerve, a branch of the left vagus nerve.

Non-perfused elements of other types of vascular rings (e.g. left arch with atretic (closed) end) or the ligamentum arteriosum might be difficult to visualize by echocardiography.

The ligamentum arteriosum (or arterial ligament) is a small ligament attached to the superior surface of the pulmonary artery and the inferior surface of the aortic arch.

After splitting from the left vagus nerve, the left recurrent laryngeal loops around the aortic arch posterior to the ligamentum arteriosum, after which it ascends to the larynx.

Initial secretion of bradykinin post-natally causes constriction and eventual atrophy of the ductus arteriosus, forming the ligamentum arteriosum between the pulmonary trunk and aortic arch.

It gives rise to the left recurrent laryngeal nerve, which hooks around the aortic arch to the left of the ligamentum arteriosum and ascends between the trachea and esophagus.

During the first breath, vasoconstriction causes the ductus arterious to close, and during adult years, tissue occludes what once was the ductus arterious, creating the ligamentum arteriosum.

Coarctation of the aorta, or aortic coarctation, is a congenital condition whereby the aorta narrows in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts.

The left vagus nerve, which passes anterior to the aortic arch, gives off a major branch, the recurrent laryngeal nerve, which loops under the aortic arch just lateral to the ligamentum arteriosum.

After pulling the left lung aside, the layer (mediastinal pleura) above the left arch is incised and the left arch and the ligamentum arteriosum are dissected out and separated from the surrounding structures.

Above, it is connected to the concavity of the aortic arch by the ligamentum arteriosum, on the left of which is the left recurrent nerve, and on the right the superficial part of the cardiac plexus.

The aortic arch loops over the right pulmonary artery and the bifurcation of the pulmonary trunk, with which it remains connected by the ligamentum arteriosum, a remnant of the fetal circulation that is obliterated a few days after birth.

On the right side, the artery of Arch 6 is obliterated while, on the left side, the artery persists as the ductus arteriosus; circulatory changes immediatey following birth cause the vessel to close down leaving a remnant, the ligamentum arteriosum.
