What is a ductus diverticulum?
What is a ductus diverticulum?
Imaging description Ductus diverticulum (DD) is an anatomic variant incidentally found at cardiovascular imaging characterized by a smooth bulge of the anterior wall of the aorta at the aortic isthmus, just distal to the origin of the left subclavian artery.
What is aortic ductus diverticulum?
Aortic ductus diverticulum is a developmental outpouching of the thoracic aorta which may be mistaken for an acute aortic injury.
What is an aortic pseudoaneurysm?
Aortic pseudoaneurysms are contained ruptures of the aorta in which the majority of the aortic wall has been breached, and luminal blood is held in only by a thin rim of the remaining wall or adventitia.
What is a ductal aneurysm?
Congenital aneurysm of ductus arteriosus (DAA) is a rare condition caused by saccular dilatation of ductus arteriosus and is an important cause of extrinsic compression on the airways, producing stertorous breathing in the newborn.
Where is the isthmus of the aorta?
The aortic isthmus is the segment of aorta located between the origin of the left subclavian artery and the connection of the ductus arteriosus to the descending aorta.
Is ligamentum arteriosum normal?
The ligamentum arteriosum (arterial ligament), also known as the Ligament of Botallo or Harvey’s ligament, is a small ligament attaching the aorta to the pulmonary artery. It serves no function in adults but is the remnant of the ductus arteriosus formed within three weeks after birth.
How can you tell the difference between an aneurysm and a pseudoaneurysm?
A saccular-shaped aneurysm bulges or balloons out only on one side. A pseudoaneurysm, or false aneurysm, is not an enlargement of any of the layers of the blood vessel wall. A false aneurysm may be the result of a prior surgery or trauma.
What does a pseudoaneurysm look like?
The symptoms of a pseudoaneurysm are usually pain and swelling at the site of the blood vessel damage. You might feel a lump under your skin where the blood is pooling in the tissue. It may feel tender or painful to the touch. It may feel like it’s throbbing.
