When the sperm fertilizes, or meets, the egg, this fertilized egg is called the zygote. The zygote goes through a process of becoming an embryo and developing into a fetus. The female reproductive system includes a group of organs in a woman's lower belly and pelvis. The uterus is where a fetus, or baby, grows. It is a hollow, pearâshaped organ with a muscular wall. There are two ovaries, one on either side of the uterus.
An aortic aneurysm is an enlargement (dilation) of the aorta to greater than 1.5 times normal size. They usually cause no symptoms except when ruptured. Occasionally, there may be abdominal, back, or leg pain. They are most commonly located in the abdominal aorta, but can also be located in the thoracic aorta. Aortic aneurysms cause weakness in the wall of the aorta and increase the risk of aortic rupture. When rupture occurs, massive internal bleeding results and, unless treated immediately, shock and death can occur.
Background. Thoracic aortic aneurysm (TAA) is a life-threatening condition that causes significant short-and long-term mortality due to rupture and dissection. Aneurysm is defined as dilatation of the aorta of greater than 150% of its normal diameter for a given segment.neurysms may affect one or more segments of the thoracic aorta, including the ascending aorta, the arch, and the descending thoracic aorta. As many as 25% of patients with TAA also have an abdominal aortic aneurysm.
