动脉瘤
Overview
An aneurysm is an abnormal bulge or ballooning of an artery, caused by weakening of the artery wall. 主动脉瘤发生在主动脉上, the major blood vessel that carries blood from your heart to the rest of the body. Similar to the popping of an overinflated balloon, the aneurysm may rupture if the artery wall stretches too thin. When aneurysms rupture, there is the potential for fatal bleeding.
我们治疗动脉瘤的方法
UCSF is home to a world-renowned program in endovascular surgery, one of the largest and oldest programs of its kind. Our vascular surgeons helped pioneer many of the endovascular procedures that are used to treat aortic aneurysms today. These minimally invasive procedures offer many benefits compared to traditional open surgery, 包括更快的恢复, less postoperative pain and reduced risk for patients with other medical conditions.
每年, we perform more than 150 repairs of endovascular aneurysms, more than any other medical center on the West Coast. We have extensive experience with technically challenging surgeries for complex aortic aneurysms, such as those involving arteries supplying blood to the kidneys or intestines.

迹象 & 症状
Many patients with aneurysms of the aorta have no 症状, causing the condition to remain undiagnosed until the aneurysm ruptures. Other aneurysms are discovered during computed tomography (CT) or magnetic resonance imaging (MRI) scans that are performed for other health problems.
Some patients have mild 症状 of pain or discomfort in the area of the aneurysm. 严重的腹部, back or groin pain in a patient with an aneurysm could be due to a ruptured aneurysm and should be treated immediately.
诊断
Almost all aneurysms can be detected with safe and painless non-invasive tests, such as ultrasound studies or computed tomography (CT) scans.
Large aneurysms may require surgery while small ones are closely monitored with ultrasound and may never grow large enough to require surgery.
治疗
动脉瘤 of the aorta that are large enough to require repair are treated with one of the following:
- 传统的手术. A synthetic graft is sewn inside the aneurysm to the artery above and below it to prevent the aneurysm from rupturing.
- 血管内修复. A newer procedure that uses a catheter inserted in the groin to guide a self-expanding graft to the aneurysm. 血管内修复 does not require an abdominal incision and has a substantially shorter recovery. Not all aneurysms are suitable for endovascular repair.
Smaller aneurysms are monitored with ultrasound tests to watch their growth. Many never enlarge to a size that requires repair.
动脉瘤 also can occur in other blood vessels, particularly in the arteries of the leg. These aneurysms are dangerous because they generally contain blood clots. The blood clots can break off and block arteries that are further downstream.
In other instances, the entire aneurysm can clot. Both of these situations can lead to decreased blood flow to the leg. 因此, aneurysms found in the arteries of the leg are usually repaired as soon as possible once they are detected.
