Aneurysms: What They Are, Signs to Watch For, and Next Steps

An aneurysm is a weak spot in a blood vessel that balloons out. They most often show up in the brain (cerebral aneurysm) or the aorta (abdominal or thoracic). Small aneurysms may cause no symptoms; larger ones can press on nearby tissue or rupture, which is life‑threatening.

Risk factors include high blood pressure, smoking, high cholesterol, being older, and a family history of aneurysms. Certain genetic conditions and past infections can raise risk too. If you smoke or a close relative had an aneurysm, mention it to your doctor — you might need a check.

How aneurysms show up and how we find them

Symptoms depend on where the aneurysm is. Brain aneurysms can cause sudden, severe headaches, nausea, blurred vision, neck stiffness, or loss of consciousness if they leak or burst. Aortic aneurysms may cause constant back or belly pain, a pulsing feeling near the navel, or sudden collapse when they rupture. Still, many aortic aneurysms have no symptoms until they’re large.

Doctors use imaging to diagnose aneurysms. Abdominal aneurysms are often found with a simple ultrasound. CT scans, MRI, CT angiography, and catheter angiograms are used for brain and thoracic aneurysms. These tests show the size, shape, and exact location — the facts your care team needs to choose treatment.

Treatments, what to expect, and daily steps

Treatment depends on size, location, and rupture risk. Small, stable aneurysms are often watched with regular scans and strict blood pressure control. Larger or risky aneurysms usually need repair. For aortic aneurysms that are big or growing, surgeons may place a stent graft via an artery (endovascular repair) or do open surgery. Brain aneurysms are often treated with coil embolization (tiny coils packed into the aneurysm) or clipping during surgery.

Recovery varies. Endovascular procedures usually mean shorter hospital stays and faster recovery. Open surgery takes longer to heal but may be the right choice for some patients. Ask your surgeon about expected hospital time, restrictions after surgery, and follow‑up imaging.

Practical steps you can take now: keep blood pressure in the target range, quit smoking, manage cholesterol, stay active, and avoid heavy straining if advised. Follow medication plans and keep imaging appointments. For men aged 65–75 who have ever smoked, a one‑time abdominal ultrasound is recommended by several health groups to screen for abdominal aortic aneurysm.

Know the emergency signs: a sudden, worst‑ever headache, sudden weakness or speech trouble, or severe chest/abdominal pain with fainting. Call emergency services immediately — faster care can make a big difference.

If you have concerns about family history or symptoms, book a visit. Early testing, sensible risk control, and clear talks with your doctor are the simplest ways to lower danger and plan the right treatment for you.
