Aneurysm is a disease of dilated arteries that can occur anywhere in the body.
Aneurysm is defined as a permanent, limited dilatation of an arterial vessel with a diameter greater than 50% of the normal diameter. Arteries exist throughout the body and all arteries that dilate have the potential to develop into an aneurysm. Depending on the anatomical location of the lesion, it can be categorized as an abdominal aortic aneurysm, a thoracic aortic aneurysm, a common femoral aneurysm, and an intracranial aneurysm.
Generally speaking, small aneurysms usually have no obvious clinical symptoms. However, as the aneurysm continues to expand, some patients may present with abdominal pain, chest pain, nausea and vomiting. As the aneurysm continues to progress, the wall of the aneurysm will become thinner and thinner, thus there is a risk of rupture or tear. Once the aneurysm ruptures or tears, it is easy to cause massive bleeding, which may endanger the patient’s life.
It is recommended that patients who have discovered an aneurysm should seek prompt medical attention and active treatment under the guidance of a doctor to avoid delaying the condition.
