descending aortas การใช้

• Such an injury would sever the inferior vena cava and the descending aorta.
• The inferior mediastinum is exposed to the level of the anterior aspect of the descending aorta.
• Then, last December, her descending aorta tore while she was loading groceries into her car.
• Aneurysms in the ascending aorta may require surgery at a smaller size than aneurysms in the descending aorta.
• By birth, the dorsal aorta becomes the descending aorta, while the genital ridges form the gonads.
• Instead medical management is the common response to treating and keeping dissections of the descending aorta under control.
• The ligamentum arteriosum connects to the junction between the arch of aorta and the descending aorta in foetal life.
• The medial surface of the descending aorta and the distal end are also carefully dissected away from the esophagus.
• It is often joined by the ligamentum arteriosum ( or patent ductus arteriosus ) where it forms the descending aorta.
• The ligamentum is divided and two vascular clamps are placed on the junction of the left arch with the descending aorta.
• Today, said Whittemore, the risk of death in operations on the descending aorta has dropped to 10 percent or less.
• The aortic arch is transected and the stent graft device is delivered in an ante-grade fashion in the descending aorta.
• The aortic arch ends and the descending aorta begins at the level of the intervertebral disc between the fourth and fifth thoracic vertebrae.
• In patients with thoracic aortic disease involving the arch and descending aorta, it is not always possible to perform a completely endovascular repair.
• The hardest segment to repair is the descending aorta in the chest along the backbone, with its many tributaries that supply the spinal cord and internal organs.
• The two arches join to form the descending aorta which is usually on the left side ( but may be right-sided or in the midline ).
• In March, they operated on my dad for an aneurysm on his descending aorta, a medical condition I am told you don't mess around with.
• In patent ductus arteriosus, a congenital disorder, the fetal ductus arteriosis fails to close, leaving an open vessel connecting the pulmonary artery to the proximal descending aorta.
• The right aortic arch is completing the vascular ring by passing to the right and then behind the esophagus and trachea to join the usually left-sided descending aorta.
• On the same surface, immediately above the hilum, is a well-marked curved groove for the aortic arch, and a groove below it for the descending aorta.
