Aneurysms are often asymptomatic until they reach a size that increases the risk of rupture. In cases where symptoms are present, patients may experience localized pain, a pulsating sensation near the affected blood vessel, or, in the case of a ruptured aneurysm, sudden severe pain accompanied by signs of shock, such as rapid heartbeat and pale skin. For visceral artery aneurysms, symptoms may include abdominal pain, nausea, or gastrointestinal bleeding depending on the organ affected. Early diagnosis is essential, as many aneurysms can exist without any warning signs.
