Abdominal aortic aneurysm 6 cm has a 10% chance of rupture. Abdominal aortic aneurysms are usually caused by atherosclerosis, which manifests as an aneurysmal dilatation of the abdominal aorta. Severe atherosclerosis, smoking, and trauma increase the risk of aneurysm rupture. In particular, aneurysms larger than 5 centimeters in diameter are more likely to rupture, and the chance of rupture is around 10%, with a high mortality rate. Surgical resection and treatment are needed as soon as possible to avoid the greater risk of rupture of the aneurysm. If the abdominal aortic aneurysm is smaller than 5 cm, you can temporarily disregard the treatment and pay attention to regular review in the vascular surgery department of the hospital, do abdominal CT, abdominal ultrasound, magnetic resonance or angiography, etc. to observe the changes of the abdominal aortic aneurysm and so on. Once abnormalities are found, go to regular hospitals for standardized treatment without delay, so as to avoid rupture of the aneurysm causing hemorrhage, which may also be life-threatening.
