什么是腹腔动脉瘤?
The normal size of the aorta in our abdomen ranges from 1.7厘米至2厘米.5厘米，取决于你是男是女. 这相当于一枚美国镍币的大小. 医生 诊断动脉瘤 when your aorta is larger than 3 cm in diameter, which is about the size of a silver half-dollar.
If you are diagnosed with an abdominal aortic aneurysm (AAA, “aaa”), 医生会考虑你主动脉的大小, 你的症状, and your overall health before deciding on the best treatment for you.
AAA级游戏是什么感觉?
The most common symptom of a AAA is nothing, but occasionally they can cause abdominal or back pain.
AAA的成因?
As your blood vessel stretches and gets bigger, it grows thinner. 有时这种生长本身会引起腹痛. Many patients get a CT scan after having abdominal pain, but a CT scan may not show anything unusual.
At a certain size (or diameter), your aorta has a higher chance of leaking. 主动脉渗漏通常被认为是紧急情况. We recommend aneurysms get fixed before they get too big.
幸运的是, doctors have studied thousands and thousands of aortic aneurysms, so we have a lot of information about how fast they grow and what the risks of leaking are at the different sizes.
如何诊断AAA?
The most common way that doctors diagnose abdominal aortic aneurysms is when a patient has a CT scan for another health problem. 换句话说，它们通常是偶然发现的.

有些人患aaa的几率更高. 这些人可以得到 通过超声波检查动脉瘤. People who have a higher chance of developing a AAA include:
- men over the age of 65 who have smoked at least 100 cigarettes in their lifetime, and
- people who have a family member with an abdominal aortic aneurysm.

腹主动脉瘤治疗
一旦你被诊断为AAA, the next step is for your doctor to monitor (watch) your aneurysm to learn how fast it is growing. 医生 can usually monitor your aneurysm by giving you an ultrasound each year.
大多数动脉瘤每年生长不到5毫米. Depending on the size of your aneurysm, your doctor may monitor it for many years.
If your aneurysm gets larger and may need to be repaired, your doctor will usually switch to CT scans to monitor your aneurysm. CT scans give doctors more detailed information about your aneurysm and can help them plan how to repair it.

What Size of Abdominal Aortic Aneurysm Requires Surgery?
Once your aneurysm is larger than 5 cm in a woman or 5.5 cm in a man (about the size of the short side of a credit card) it's time to plan on fixing it. Just like people come in all different shapes and sizes, so do aneurysms.
The shape and location of your aneurysm plays a big role in the different options for repair. The goal of fixing an aneurysm is to re-route the blood flow going through it so there's no longer any pressure on the thin wall of your aorta. 医生可以通过两种不同的方式做到这一点.
One way to fix an aneurysm is to perform a surgery where doctors sew in a new blood vessel, 通常由材料制成, 取代扩大的区域. 如果你做了这个手术, you will likely need to stay in the ICU for at least one to two nights and in the hospital for over a week.

A second way to fix an aneurysm is to travel inside the blood vessels and re-line the enlarged area with an endograft. An endograft is a combination of material and a metal framework to hold your blood vessel in place. 医生 can usually perform an endograft without making any incisions (cuts), and most patients can go home the day after the surgery.
