It’s one of those words you’ve probably heard before—maybe on the news or in a medical drama—but unless it’s touched your life or a loved one’s, it can feel distant. Quiet. Maybe even a little mysterious.
But here’s the thing: aneurysms can be silent until they become serious. And knowing what they are—and when to take action—can make all the difference.
At OC Surgeons, we’re passionate about helping our community understand vascular health, because early detection and expert care save lives. Let’s take a closer look at what an aneurysm really is, what to watch out for, and when it’s time to talk to a specialist.
What Exactly Is an Aneurysm?
An aneurysm occurs when a section of an artery—a blood vessel that carries blood from the heart to the rest of the body—weakens and bulges outward like a balloon. Over time, that bulge can grow, and in some cases, it can rupture. A ruptured aneurysm can cause life-threatening internal bleeding.
Aneurysms most commonly occur in the aorta (the body’s largest artery), particularly in the abdominal aorta (abdominal aortic aneurysm or AAA), but they can also happen in the brain, chest, or behind the knee.
The danger isn’t just in the rupture—unruptured aneurysms can press on nearby structures or lead to blood clots, both of which may cause serious complications.
Why Do Aneurysms Happen?
Aneurysms don’t have a single cause. They often develop slowly and silently, influenced by a combination of genetics, lifestyle, and medical history. Some common risk factors include:
- Age (more common after age 60)
- High blood pressure
- Smoking
- Atherosclerosis (hardening of the arteries)
- Family history of aneurysms
- High cholesterol
- Infections or trauma (in rare cases)
While some people are born with a predisposition, others develop aneurysms due to wear and tear on the arteries over time.
Early Signs: What to Watch For
Aneurysms are often called “silent threats” because they frequently don’t cause symptoms until they’re large or rupture. That said, there are times when the body does send signals. Being aware of them is key:
Abdominal Aortic Aneurysms (AAA)
- A pulsating feeling near the navel
- Deep, constant pain in the abdomen or side
- Back pain
Thoracic Aortic Aneurysms
- Chest or upper back pain
- Shortness of breath
- Difficulty swallowing or hoarseness
Ruptured Aortic Aneurysms
- Sudden, severe pain in the abdomen or low back
- Low blood pressure
- A pulsating feeling near the navel
If any of these symptoms occur suddenly, especially signs of a ruptured aneurysm, seek emergency care immediately. Aneurysms can become fatal in minutes.
When to See a Vascular Specialist
Even in the absence of symptoms, certain people should consider aneurysm screening, especially if they:
- Are over age 65 and have smoked
- Have a family history of aneurysms
- Have high blood pressure or vascular disease
At OC Surgeons, we offer non-invasive vascular screenings and advanced imaging to detect aneurysms early—often before they become dangerous. If an aneurysm is found, our team provides personalized care plans, including monitoring, lifestyle counseling, and if needed, state-of-the-art surgical or endovascular repair.
Modern Treatment Options: Safe, Targeted, Effective
Not all aneurysms require immediate surgery. Many small or slow-growing aneurysms are monitored with imaging and lifestyle modifications. But if treatment is needed, our vascular surgeons are experienced in:
- Endovascular Aneurysm Repair (EVAR), a minimally invasive procedure using a stent graft to reinforce the weakened artery wall
- Open Surgical Repair, often recommended for larger or complex aneurysms
- Hybrid Techniques, combining both open and minimally invasive approaches for customized care
We walk with each patient through every option, every step of the way.
FAQs About Aneurysms
In most cases, no. Aneurysms typically grow slowly and don’t cause symptoms until they are large or rupture. However, some people may feel a pulsing sensation (especially in the abdomen), experience pain, or feel pressure depending on the aneurysm’s location.
Aneurysms are often detected through imaging studies such as ultrasound, CT scans, or MRIs. These tests are non-invasive and provide detailed information about the size and location of the aneurysm.
As with any surgery, there are risks involved, but advancements in vascular surgery—especially minimally invasive techniques like EVAR—have made aneurysm repair safer and more effective than ever. Your care team at OC Surgeons will carefully assess your condition and recommend the safest, most effective treatment plan tailored to you.
