Aneurysms: Identifying and Managing a Silent Threat in Singapore

An aneurysm is a serious medical condition that occurs when the wall of a blood vessel weakens and bulges. While many aneurysms are asymptomatic, they can be life-threatening if they rupture, leading to severe internal bleeding. Understanding the types of aneurysms, their symptoms, and the importance of early detection can help prevent complications.

What is an Aneurysm?

An aneurysm is an abnormal bulging or ballooning in the wall of an artery. This can occur in various parts of the body, but aneurysms most commonly develop in the brain (cerebral aneurysm), the aorta (aortic aneurysm), or the arteries in the legs or chest. Over time, the pressure from blood flow can cause the aneurysm to grow, increasing the risk of rupture.

Types of Aneurysms

There are several types of aneurysms, each affecting different parts of the body:

1. Aortic Aneurysm: This type occurs in the aorta, the main artery that carries blood from the heart to the rest of the body. It is further divided into:
2. Thoracic Aortic Aneurysm (TAA): Occurs in the chest area.
3. Abdominal Aortic Aneurysm (AAA):: Occurs in the abdomen, and is more common than TAA.
4. Cerebral Aneurysm: This occurs in the blood vessels of the brain and can lead to a hemorrhagic stroke if it ruptures.
5. Peripheral Aneurysm: This occurs in arteries other than the aorta or brain, such as in the legs or groin area.

Causes and Risk Factors

Several factors can contribute to the development of aneurysms, including:

• High Blood Pressure: Elevated blood pressure can weaken the walls of arteries over time.
• Atherosclerosis (Hardening of the Arteries): Fatty deposits in the arteries can cause them to become stiff and narrow, leading to aneurysms.
• Smoking: Smoking weakens the artery walls and increases the risk of aneurysm formation and rupture.
• Family History: Genetics can play a role, and having a family member with an aneurysm increases your risk.
• Age and Gender: Aneurysms are more common in individuals over the age of 60 and tend to affect men more frequently than women.

Symptoms of an Aneurysm

Most aneurysms do not cause noticeable symptoms until they are large or about to rupture. However, in some cases, the following symptoms may be present:

1. Aortic Aneurysm Symptoms
   • Pain in the abdomen, back, or chest (depending on the location of the aneurysm).
   • A pulsating feeling near the belly button (in the case of an abdominal aortic aneurysm).
2. Cerebral Aneurysm Symptoms
   • Severe, sudden headache, often described as “the worst headache of my life.”
   • Nausea and vomiting.
   • Blurred vision or sensitivity to light.
   • Loss of consciousness or seizure.
3. Peripheral Aneurysm Symptoms
   • Pain in the affected limb (such as the leg).
   • Coldness or lack of pulse in the limb.

When an Aneurysm Ruptures

A ruptured aneurysm is a medical emergency that requires immediate attention. The symptoms of a rupture include:

• Severe Pain: Sudden and intense pain at the site of the aneurysm.
• Loss of Consciousness: Fainting or losing consciousness due to blood loss.
• Low Blood Pressure: Sudden drop in blood pressure due to internal bleeding.

A ruptured aneurysm can be fatal, so it’s important to seek emergency medical care if you experience these symptoms.

Preventing and Managing Aneurysms

While some risk factors for aneurysms, such as age and family history, cannot be controlled, there are steps you can take to reduce your risk:

• Control Blood Pressure: Keep blood pressure in a healthy range by managing stress, exercising regularly, and taking prescribed medications if necessary.
• Quit Smoking: Smoking is a significant risk factor for aneurysms. Quitting smoking can greatly reduce your risk.
• Eat a Healthy Diet: A balanced diet low in saturated fats and high in fruits, vegetables, and whole grains can help prevent atherosclerosis.
• Get Regular Check-Ups: Routine screenings, especially if you have risk factors, can help detect aneurysms early. Ultrasound imaging is commonly used to check for abdominal aortic aneurysms.

Treatment of Aneurysms

Treatment depends on the size, location, and risk of rupture of the aneurysm. Options include:

• Monitoring: Small aneurysms may only require regular monitoring with imaging tests to track their growth.
• Medications: Medications to lower blood pressure or cholesterol may be prescribed to reduce the risk of aneurysm growth.
• Surgery: If the aneurysm is large or at risk of rupturing, surgical intervention may be necessary. This could involve repairing the aneurysm with a graft or stent.

Living with an Aneurysm

If diagnosed with an aneurysm, working closely with your doctor is essential. Follow all recommended lifestyle changes and treatment plans to reduce the risk of rupture.
