Arterial hemangiomas are benign tumors that generally have little effect on the human body if they do not rupture and bleed. However, aneurysms are serious and may be life-threatening if they rupture at a weak point and cause hemorrhage due to the localized weakness and reduced tone of the vessel wall, the abnormal wall of the vessel that is impacted by the flow of blood and forms an abnormal dilation or bulge, and the tumor continues to grow in size. Although arterial hemangiomas can occur in various parts of the blood vessels, the common sites are the aorta or cerebral artery. Aortic or cerebral artery aneurysm is a serious emergency. Most of the symptoms of arterial aneurysm are not obvious, and it can be detected before rupture and can be treated by surgery and resection; if the pain attack is sudden, persistent, and intense, and at the same time it can be accompanied by profuse sweating, nausea, low blood pressure, and shock, then it is necessary to consider the rupture of arterial aneurysm, and if rupture occurs or aneurysm is located in the operable part, it should be treated by emergency surgery. Because arterial hemangioma may rupture and bleed, and thrombus or plaque may also appear, and embolus may be formed easily after dislodging, and rupture and bleed at any time and in any place, so it is a serious disease in clinic. Therefore, if an arterial hemangioma is found, it should be treated in time to avoid life-threatening situations.
