Why are aneurysms dangerous?
Aneurysms are dangerous because when the artery stretches, it becomes weakened. If the wall of the artery ruptures, or “pops”, it can cause major and often fatal internal hemorrhage (bleeding). Larger aneurysms are more likely to break, but all aneurysms need to be monitored closely. Many patients who have aneurysms are likely to develop aneurysms in other parts of their body (see above: “What is an Aneurysm”). Patients who have been diagnosed with an aneurysm need to see a vascular surgeon periodically, so that new aneurysms may be appropriately treated.
