What Are the Warning Signs of an Aortic Aneurysm?

The honest answer: most aortic aneurysms have no warning signs at all. That's precisely why screening exists — and why a 15-minute ultrasound at home may be the most important test you've never thought to ask about.

The Problem: Most AAAs Feel Like Nothing

An abdominal aortic aneurysm (AAA) is a dangerous enlargement of the main artery running through the abdomen. As the aortic wall weakens and balloons outward, most people feel absolutely nothing. No pain. No pressure. No pulsing. The aneurysm grows silently for years — until it ruptures. At that point, survival odds drop dramatically within minutes. Screening isn't just recommended — it's endorsed by the U.S. Preventive Services Task Force (USPSTF) with a Grade B recommendation for men aged 65–75 who have ever smoked.

A 15-MINUTE SCAN GIVES YOU THE ANSWER

Most aneurysms have NO symptoms until they rupture. That's why screening matters. A 15-minute ultrasound at home measures your aorta and gives you the answer — no radiation, no referral, results in 24–48 hours.

If you experience sudden, severe abdominal or back pain, a pulsating mass in your abdomen, or signs of shock (rapid heart rate, dizziness, loss of consciousness) — call 911 immediately. AAA rupture is a life-threatening emergency.

Risk Factors That Make Screening Necessary

You can't feel an aneurysm growing. But you can know whether you're at elevated risk — and act accordingly.

The USPSTF Screening Criteria — Who Qualifies

The U.S. Preventive Services Task Force gives a Grade B recommendation (their second-highest rating) for one-time AAA screening with abdominal ultrasound for:

  • Men aged 65–75 who have ever smoked (at least 100 cigarettes in their lifetime)

Medicare covers a one-time AAA screening ultrasound for qualifying male beneficiaries who have ever smoked, referred by a physician. BlackPoint Diagnostics also offers self-pay screening directly at home for those who want answers without navigating the referral process.

Additional Risk Factors Worth Discussing with Your Physician

Male sex, age 65+

Men are 5–10x more likely to develop AAA than women.

History of smoking

The strongest modifiable risk factor for AAA development.

Family history of AAA

Having a first-degree relative with AAA significantly raises risk.

High blood pressure

Chronic hypertension stresses arterial walls over time.

Known vascular disease

Atherosclerosis elsewhere raises risk of aortic involvement.

What Happens If an Aneurysm Is Found

If screening identifies an enlarged aorta, the management depends on the size. Aortas measuring 3–5.4 cm are typically monitored with periodic ultrasound to track growth rate. Aortas 5.5 cm or larger — or those growing rapidly (more than 5 mm in six months) — are generally referred to a vascular surgeon for evaluation of repair. The goal of screening is to find aneurysms while they're still in the monitorable range, before rupture becomes the first sign.

The Study: AAA Screening Ultrasound

The simplest screening test you haven't gotten yet — and the one with potentially the most lifesaving value.

AAA Screening · $397

Aortic Diameter Measurement — 15 Minutes, No Radiation

A focused abdominal ultrasound that measures the diameter of the aorta at the level of the renal arteries and distally. Evaluates for aneurysmal dilation (3 cm or greater), assesses the extent of any enlargement, and documents aortic wall characteristics. Takes approximately 15 minutes. Completely non-invasive, no radiation, no contrast agents.

  • Aortic diameter at multiple levels
  • Identifies aneurysmal dilation
  • No radiation — safe for screening use
  • USPSTF-endorsed screening modality
  • Results reviewed and delivered in 24–48 hours

Why Screening Matters — The Numbers Are Stark

80%+

Mortality rate for ruptured AAA — most patients do not survive long enough to reach the operating room

<5%

Operative mortality for elective repair of a non-ruptured AAA caught through screening

Without Screening

  • → Aneurysm grows silently for years
  • → No symptoms until rupture
  • → Rupture → emergency surgery or death
  • → Survival rate after rupture: under 20%
  • No warning. No second chance.

With Screening

  • → Aorta measured at home in 15 minutes
  • → Normal result: peace of mind
  • → Small AAA found: monitored with ultrasound
  • → Large AAA found: elective repair planned
  • Knowledge. Options. Control.

What Happens During the Scan

Emanuel comes to your home with hospital-grade portable ultrasound equipment. For an AAA screening, the scan is brief and completely non-invasive. No preparation is required, though a light meal beforehand is ideal to reduce bowel gas that can occasionally limit visualization.

You lie on your back. Ultrasound gel is applied to the abdomen and the transducer is passed along the path of the aorta — from just below the sternum to where it divides. The aorta's diameter is measured at the level of the renal arteries and at the widest point. The study takes approximately 15 minutes. No pain. No radiation. No contrast.

The result is either reassuring (normal diameter, no aneurysm) or actionable (enlarged aorta, with documented measurements your physician can act on). The formal written report is delivered within 24–48 hours.

Frequently Asked Questions

What are the warning signs of an aortic aneurysm?

Most aortic aneurysms have no warning signs at all. A small percentage of people notice a pulsating feeling in the abdomen, deep abdominal or back pain, or groin discomfort. But the majority of AAAs are discovered incidentally or through proactive screening — not through symptoms. This is precisely why screening is recommended for high-risk groups.

Who should get screened for an abdominal aortic aneurysm?

The USPSTF recommends one-time AAA screening for men aged 65–75 who have ever smoked (at least 100 cigarettes lifetime). Additional risk factors that may warrant discussion with a physician include family history of AAA, high blood pressure, atherosclerosis, and history of other vascular aneurysms. Medicare covers one-time screening for qualifying beneficiaries.

What does an AAA screening ultrasound measure?

The scan measures the diameter of the abdominal aorta. A normal aorta is less than 3 cm. An aorta measuring 3–5.4 cm is considered a small to medium aneurysm, typically monitored with periodic ultrasound. An aorta 5.5 cm or larger — or one growing rapidly — is generally referred for surgical evaluation.

Do I need a referral for an AAA screening ultrasound in Maine?

No referral is required for self-pay screening. You can book directly through our website and we come to your home. Results are reviewed and delivered within 24–48 hours. If you want Medicare to cover the screening, a physician referral is required — speak with your PCP.

When is an aortic aneurysm a medical emergency?

A ruptured AAA is a life-threatening emergency. Symptoms include sudden, severe abdominal or back pain, a pulsating abdominal mass, and signs of shock. Call 911 immediately — every minute matters. AAA rupture carries extremely high mortality, which is why screening before rupture is the only reliable strategy.
