The severity of an arterial hemangioma is related to where the aneurysm is located. If the arterial hemangioma appears at the aorta or major blood vessels in the brain (such as the anterior cerebral artery, etc.), the condition will be more serious; if the arterial hemangioma appears at the small arteries at the end of the limb (such as the ulnar collateral artery of the little finger), the condition will be relatively mild.
Arterial hemangioma will lead to localized weakness and loss of tension of the vessel wall, which will easily rupture and bleed under the long-term impact of blood flow. Therefore, if the arterial hemangioma is found in the aorta or the arteries of the brain (such as the anterior cerebral artery, etc.), it will bleed more after rupture, and the condition is relatively serious, so the condition should be handled in a timely manner once it is detected.
If the aneurysm is found at the end of the limb, such as the ulnar artery of the little finger, even if it ruptures and bleeds, the amount of bleeding is relatively small, and usually does not cause serious consequences, so the condition is relatively mild.
To sum up, whether the arterial hemangioma is serious or not needs to be analyzed according to the specific condition.
