What are the symptoms of arterial aneurysm?

When an arterial aneurysm develops, symptoms may include a localized pulsating mass, pain, increased skin temperature, limb numbness and weakness, and signs related to rupture and bleeding. If sudden severe pain or massive bleeding occurs, immediate medical attention is recommended.

1. Localized pulsating mass: A soft, palpable mass that pulses with the heartbeat can be felt at the site of the aneurysm. It may feel slightly elastic when pressed and tends to gradually enlarge as the condition progresses. This is a relatively typical early sign of arterial aneurysm.

2. Pain: Initially, the pain is often mild, manifesting as a dull ache or slight discomfort. If the aneurysm compresses surrounding nerves or muscles, the pain may intensify and become persistent or intermittent stabbing pain. It may worsen with physical activity and significantly impair daily functioning.

3. Increased skin temperature: The skin over the aneurysm area feels warmer than the surrounding normal skin, and this temperature difference is clearly noticeable upon touch. It results from abundant blood flow within the aneurysm and accelerated local metabolism.

4. Limb numbness and weakness: If the aneurysm occurs in an artery of the limbs, it may compress nearby nerves or impair blood supply to the limb, leading to numbness and reduced sensation. In severe cases, it can cause muscle weakness, restricted movement, and even compromise normal limb function.

5. Symptoms related to rupture and bleeding: Severe localized pain may occur before rupture. After rupture, superficial aneurysms may lead to obvious external bleeding, while internal aneurysms may cause symptoms such as abdominal pain or hemoptysis (coughing up blood), and in severe cases, may result in shock.

In daily life, individuals should pay attention to any unusual lumps or pain in the body, avoid strenuous exercise and trauma to areas where aneurysms may exist, maintain regular作息 (daily routines), keep blood pressure stable, undergo regular vascular examinations, and promote overall vascular health.
