Abdominal hemangiomas can present with abdominal pain because they develop in a distended form and can irritate the abdominal organs and nerves. If the hemangioma ruptures and bleeds, the pressure in the abdominal cavity will increase, and the abdominal pain will be obvious, and acute gastrointestinal bleeding or hemorrhagic shock will occur. Because abdominal vascular hemangiomas are usually arterial hemangiomas, such as splenic aneurysm, superior mesenteric artery hemangioma or abdominal aortic hemangioma or renal artery hemangioma. In this case, the symptoms of hemorrhage are manifested, because arterial bleeding is very violent. If left untreated, the patient can suffer from hemorrhagic shock, which can even endanger the patient’s life. The specific treatment is determined by the severity of the condition and the actual condition of the patient.
