Aneurysm

Overview of Aneurysm in India

An aneurysm is often described as a quiet, concealed ailment with which most people have no idea they even have until something bad happens to them. For example, think of a tire that has a weak point slowly swelling outwards over time. That's essentially how aneurysms behave; they're abnormal bulges or balloons that usually occur on the walls of blood vessels.

There are various types of aneurysms; however, the primary concern regarding aneurysms is when they rupture, creating life-threatening bleeds internal to a person’s body. This book will clarify the factors that lead to the formation of aneurysms, the varieties of aneurysms, and give the reader the information needed to identify potential warning signs. Knowing these things will be the first step in preventing an aneurysm or receiving treatment in time to save someone's life.

What Is An Aneurysm?

A weak or enlarged section of an artery is called an aneurysm, similar to a bulging balloon. Arteries are blood vessels that transport oxygenated blood from your heart to every tissue and organ in the body, and if the wall of one of those arteries weakens, the pressure from the blood can create a bulge or aneurysm.

Most of the time you will not feel any pain from an aneurysm. Many people do not realize they have an aneurysm until it ruptures or bursts, which can be life-threatening.

Types of Aneurysm:

Any artery in the body may develop an aneurysm, although the aorta, brain, spleen, and leg are some of the most common sites for aneurysms to occur. In addition, the main types of aneurysms include the following:

Aortic Aneurysms:

The aorta is the biggest blood vessel in the body, extending from the left side of the heart in a downward direction through the chest and abdomen before splitting into two arteries that continue down each leg. The aorta is one of the most common places where an aneurysm may occur. When an aneurysm occurs in the chest region of the aorta, it is referred to as a thoracic aortic aneurysm. When an aneurysm occurs in the abdominal region of the aorta, it is referred to as an abdominal aortic aneurysm. This is the most commonly encountered type of aortic aneurysm.

Cerebral (Brain) Aneurysms:

Cerebral (or brain) aneyrusms occur within the blood vessels that supply the brain with blood and oxygen. Cerebral aneurysms can range in size and are often asymptomatic. Even if you have a cerebral aneurysm, it is possible that you are completely unaware of it if it develops in a blood vessel that is located deep inside your brain. Cerebral aneurysms may also cause bleeding when they rupture.

Peripheral Aneurysms 

A Peripheral Aneurysm (Peripheral Arterial Aneurysm) may develop in various areas other than the aorta (e.g., knees, spleen, groin, intestines, thighs, neck, or kidneys). ruptures from Peripheral Aneurysms are much less likely than from Aortic Aneurysms. The most common type of Peripheral Aneurysm is a Popliteal Aneurysm, found in the knee area.

Cirsoid Aneurysms 

A Cirsoid Aneurysm occurs when there is a malformation or defect at birth of multiple blood vessels becoming enlarged and connecting (Arterio-Venous Shunting). Cirsoid Aneurysms can lead to a mix of oxygen-rich blood with oxygen-poor blood (dangerous) and occur mainly above the shoulders and resemble nodules.

Ventricular Aneurysms 

Ventricular Aneurysms are Aneurysms that develop in the heart's Ventricles, which are the lower chambers that pump blood to the whole body, and can occur after having a Heart Attack (Myocardial Infarction).

Visceral aneurysms

Aneurysms can also hit the arteries that feed the organs in the abdomen viscera, like the hepatic artery going to the liver, the splenic artery to the spleen, or the renal artery supplying the kidneys. 

Aneurysms of arteriovenous fistulas

Aneurysms may show up in arteriovenous fistulas, those odd connections between arteries and veins. These are often fashioned surgically for dialysis access, or as part of treatment for particular vascular problems, sometimes.

Procedure:

The​‍​‌‍​‍‌​‍​‌‍​‍‌ method of treating aneurysms varies based on a number of factors, including the type, location, size, and rupture risk. The following is a summary of the main treatment options:

Monitoring

If the aneurysm is small and stable, it can simply be checked with imaging studies to make sure it is not changing in size or shape. Sometimes, for small cerebral aneurysms, just monitoring is enough if the rupture risk is very low.

Medication

Drugs can be given to get underlying diseases under control that help aneurysm formation or to lower the risk of complications. For example, one might have medicine to reduce blood pressure, cholesterol, or to prevent the formation of blood clots.

Surgical repair

Since aneurysms that are larger or of higher risk for rupture may be lethal, surgical intervention may be the only way to prevent symptoms:

Traditional open repair

This is the original open surgical method where the surgeon goes straight to the aneurysm and swaps out the weak blood vessel segment with a synthetic piece or patch.

Endovascular repair

With this method, a catheter is inserted into the blood vessels and then the stent or coils are placed so as to strengthen the weak spot and also to prevent blood flow reaching the aneurysm.

For brain aneurysms, the aneurysm can be clipped surgically or occluded with coils to stop blood from entering it and rupturing it.

Lifestyle modifications

Changes in lifestyle such as quitting smoking, doing physical activities regularly, eating healthy, and managing weight may lead to a lower risk of the aneurysm development or progression, especially among those who have also other risk factors like high blood pressure or ​‍​‌‍​‍‌​‍​‌‍​‍‌atherosclerosis.
