The ligamentum arteriosum (arterial ligament), also known as Botallo's ligament, Harvey's ligament, and Botallo's duct, [1] is a small ligament attaching the aorta to the pulmonary artery. [clarification needed] It serves no function in adults but is the remnant of the ductus arteriosus formed within three weeks after birth. [clarification needed]
The ductus arteriosus, also called the ductus Botalli, named after the Italian physiologist Leonardo Botallo, is a blood vessel in the developing fetus connecting the trunk of the pulmonary artery to the proximal descending aorta. It allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs.
The tethering of the aorta by the ligamentum arteriosum makes the site prone to shearing forces during sudden deceleration. [8] A study of people who died after traumatic aortic rupture found that in 55–65% of cases the damage was at the aortic isthmus and in 10–14% it was in the ascending aorta or aortic arch. [4]
One option is to go through the patent ductus arteriosus and continue down the aorta instead, and the other option is to continue on down the way it’s going. Hrm. Well, since it’s higher pressure over here on the left side, you might think that the blood would say “thanks, but no thanks”, and keep going down the lower pressure pulmonary ...
Coarctation of the aorta (CoA) [1] [2] is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. The word coarctation means "pressing or drawing together; narrowing". Coarctations are most common in the aortic arch. The arch may be small in babies ...
Oxygen concentration causes the production of bradykinin which causes the ductus to constrict occluding all flow. Within 1–3 months, the ductus is obliterated and becomes the ligamentum arteriosum. The ductus arteriosus connects at a junction point that has a low pressure zone (commonly called Bernoulli's principle ) created by the inferior ...
Within the first day the ductus arteriosus usually starts clamping shut, and within 3 weeks, it’s completely closed off and turned into the ligamentum arteriosum. If that ductus arteriosus doesn’t close off, then the baby is left with a patent ductus arteriosus, and this condition accounts for about 10% of all congenital heart defects, of ...
The ductus arteriosus connects to the junction between the pulmonary artery and the descending aorta in foetal life. This artery later regresses as the ligamentum arteriosum. [1] [2] The descending aorta has important functions within the body. The descending aorta transports oxygenated blood from the heart to the rest of the body. [3]
