An abdominal aortic aneurysm (AAA) is a serious yet often silent vascular condition that can develop over time without noticeable symptoms. It occurs when the wall of the abdominal aorta—the main artery that carries blood from the heart to the lower body—weakens and begins to bulge. If undetected and untreated, an aneurysm can enlarge and eventually rupture, leading to life-threatening internal bleeding.
At the forefront of vascular medicine in Southern Nevada, Dr. Luh, a Las Vegas board-certified vascular surgeon, provides expert insight into how these aneurysms form, who is at risk, and what treatment options can prevent complications. His work emphasizes early diagnosis, minimally invasive treatment, and long-term management to help patients maintain strong vascular health and avoid preventable emergencies.
What Is an Abdominal Aortic Aneurysm (AAA)?
The aorta is the body’s largest artery, responsible for supplying oxygen-rich blood to every organ and tissue below the heart. Over time, factors such as high blood pressure, smoking, and genetic predisposition can weaken its walls. When this happens, a section of the artery begins to bulge outward—forming an aneurysm.
Most abdominal aortic aneurysms develop gradually, often without symptoms. Many are discovered accidentally during imaging studies performed for other reasons. However, as the aneurysm enlarges, it may cause:
- A pulsing sensation in the abdomen
- Deep or persistent back pain
- Discomfort near the navel or lower abdomen
If an aneurysm ruptures, it can cause sudden, severe pain, rapid heart rate, and loss of consciousness. This is a medical emergency requiring immediate attention.
Who Is at Risk for an Abdominal Aortic Aneurysm?
According to Dr. Luh, age and lifestyle play significant roles in the development of aneurysms. The condition is most common in:
- Men over the age of 65
- Individuals with a history of smoking
- Those with high blood pressure or high cholesterol
- People with a family history of aneurysms
Certain genetic factors may also contribute, particularly in patients with connective tissue disorders that affect arterial strength. Routine screening is especially important for those with these risk factors.
The Role of Screening and Early Detection
One of the key ways to prevent rupture is early detection. Ultrasound screening is a simple, painless, and effective method to visualize the abdominal aorta and measure its size.
Medicare and most insurance plans cover a one-time ultrasound for men aged 65 to 75 who have ever smoked. Dr. Luh and his team encourage patients to take advantage of this screening—particularly if they fall within a higher-risk group.

Treatment Options: Personalized and Precise
Once diagnosed, treatment depends on the size and rate of growth of the aneurysm.
Monitoring Small Aneurysms
For aneurysms less than 4 centimeters in diameter, immediate surgery is often unnecessary. These are monitored regularly using ultrasound or CT scans. During this time, lifestyle changes and medical management are critical to slow progression.
Repairing Larger Aneurysms
When an aneurysm reaches 5.5 centimeters in men or 5 centimeters in women—or if it grows rapidly—surgical repair becomes necessary. There are two main types of repair:
Endovascular Aneurysm Repair (EVAR)
This minimally invasive procedure involves inserting a stent graft through small incisions in the groin. The graft reinforces the weakened artery wall, preventing rupture and restoring normal blood flow. Most patients go home within a day or two and experience a quick recovery.
Open Surgical Repair
For certain anatomies or complex aneurysms, open repair remains the best long-term solution. In this procedure, the weakened section of the aorta is replaced with a synthetic graft. Though recovery is longer, open repair provides excellent durability and outcomes for appropriate patients.
Long-Term Management and Follow-Up
Even after successful repair, regular follow-up is essential. The team at Vegas Vascular Specialists provides lifelong surveillance to ensure graft stability and monitor for any new vascular changes. This long-term approach reflects their commitment to preventive care and continuous patient support.
Conclusion
Abdominal aortic aneurysms are a serious but manageable condition when identified early and treated by experienced professionals. Through advanced diagnostics, minimally invasive solutions, and a patient-centered approach, Dr. Luh and his colleagues continue to elevate vascular care in the Las Vegas community.
If you or a loved one is at risk, don’t wait for symptoms to appear. Consult with a qualified vascular surgeon to discuss screening and prevention options that can protect your health for years to come.
