Sometimes, you can have big problems inside your body without even realizing it. One such problem is a femoral artery aneurysm. Simply put, a major blood vessel (artery) in your thigh, near the hip joint, bulges out like a balloon, which is called a ``Femoral Artery Aneurysm''. This is something to be concerned about, because sometimes you can have this condition
without any symptoms .
What exactly is a femoral artery aneurysm?
Think of a water pipe. The wall of this pipe weakens at one point and gradually bulges. That's how it is. The main blood vessel in your thigh (called the `femoral artery`)
bulges to about twice its normal size. This happens because all the layers of the blood vessel wall are stretched. When the blood vessel wall weakens in this way, it
is more likely to burst . If it bursts, this is a major blood vessel, so a large amount of blood can be lost from the body at once. That is a really dangerous situation. Also, there is a chance that a blood clot can form in this bulge and get stuck in the vein, or it can break loose and block a vein somewhere else.
Are there types of these swellings based on where they occur?
Yes, doctors classify this ``Femoral Artery Aneurysm``
according to the exact location . The main blood vessel in your thigh, let's call it the ``common femoral artery``, divides into smaller branches in several places.
- Some swellings may occur before this main vein branches .
- Others may occur at the point where the branches divide , or in the branches that divide, the ``profunda femoral artery`` or ``superficial femoral artery``.
This classification is done by location because sometimes the treatment may vary slightly depending on the specific location of the swelling.
Who is most likely to develop this condition?
Although anyone can develop this condition, called ``Femoral Artery Aneurysm,'' some people are at a slightly higher risk.
- Men are more likely to develop it than women.
- This risk is especially high for people over the age of 70 .
In addition, you may also be at risk if you have these things:
- High blood pressure : If your blood pressure is consistently high.
- High cholesterol : High cholesterol is the fatty substance in the blood.If you have high cholesterol levels .
- Connective tissue diseases : There are some rare diseases that affect the body's tissues, for example, Ehlers-Danlos syndrome or Marfan syndrome. People with these diseases are also at risk.
- Tobacco product use : This risk is higher for those who smoke cigarettes, beedis, betel nuts, or other types of tobacco.
- Atherosclerosis : This is often the main cause. Atherosclerosis is the buildup of fatty deposits on the walls of blood vessels , gradually narrowing them. If you have had a heart attack before, or if you have problems with the blood vessels in your legs, such as peripheral artery disease, you may be at risk for atherosclerosis.
- Family history : If someone in your family, such as your mother, father, or siblings, has had an aneurysm like this before, you may also be at a lower risk.
How common is this condition?
Actually, this `(Femoral Artery Aneurysm)` is
a very rare condition . That is, it is not a common disease. However, although rare, some people can have these swellings in both legs. Others can have these swellings (aneurysms) not only in this femoral artery, but also in other blood vessels in the body (for example, in the aorta in the stomach) at the same time. According to statistics, this condition affects only 0.007% of men. Among women, this percentage is even lower. So, don't be afraid to think that this is very rare, but it is very important to be aware of this.
What happens to the body when these blood vessels dilate?
If you have a `(Femoral Artery Aneurysm)`, there are two main risks. 1.
Blood clot : A blood clot can form at the site of the aneurysm and get stuck in that vein. Or, the clot can break free and travel along the bloodstream to block a small blood vessel somewhere else (for example, in the lower leg or foot). This can cut off blood flow to that area and cause problems. 2.
Rupture : This is the most dangerous. The weakened wall of the artery can bulge and burst suddenly. If that happens, as mentioned earlier, it can cause major bleeding and even death.
What are the symptoms of this?
Most of the time,
About 40% of people with this condition don't have any symptoms! That's the scary part. However, if symptoms do appear, they can include:- A lump in your groin : You may feel a lump in your groin area. Sometimes, this lump may feel like it's throbbing (pulsating).
- Swelling of the lower leg : The lower leg may become swollen.
- Pain or pressure in the groin or leg : You may experience pain in the groin, thigh area, or leg, or a feeling of pressure.
- Blood clots : As mentioned earlier, symptoms of blood clots (e.g., sudden coldness, paleness, severe pain) may occur.
- Bloating : This happens very rarely, but if it does, it can cause a serious problem with sudden, severe pain.
Remember, it can be present without any symptoms, so it's a good idea to talk to a doctor if you have risk factors.
What causes this?
There are several reasons why the wall of the femoral artery can weaken and cause this type of bulging (aneurysm).- Atherosclerosis : This is the main and most common cause . When fat builds up inside the blood vessels, the walls of the veins gradually thicken and lose their elasticity, they can no longer withstand the pressure of the blood and can become weak and bulge in some areas.
- High blood pressure : When blood pressure is high for a long time, the blood vessels are constantly under great pressure. This can also weaken the walls of the veins.
- Trauma : If a blood vessel in the thigh area is damaged by an accident or sudden injury, the area may swell up later. For example, minor injuries from certain medical procedures (such as inserting a catheter) can sometimes be the cause.
- Connective tissue diseases : As mentioned earlier, people with rare diseases that affect the connective tissue of the body, such as Ehlers-Danlos syndrome, Marfan syndrome, or adventitial cystic disease, may have a congenital weakening of the blood vessel walls.
- Behçet's disease : Behçet's disease can also cause inflammation of the blood vessels and lead to swelling like this.
This is why the wall of your femoral artery weakens and gradually stretches under the pressure of the blood, forming an aneurysm like this. How do doctors detect this?
When you go to see a doctor, they may feel a lump in your groin during a physical exam. But not every lump in your groin is an aneurysm. Sometimes it can be a hernia. So, to find out exactly what it is, and to find out exactly how big the bulge is, where it is, and what it is, your doctor will ask you to do some tests like:- Ultrasound scan : This is a simple, painless test that can look inside the blood vessel, where the swelling is, and how large it is.
- CT angiogram : This is a special type of CT scan. In this test, a special dye (contrast dye) is injected into your blood vessels, and the CT scanner takes detailed three-dimensional (3D) pictures of the blood vessels. This can provide a lot of information about the blockage.
- M.R. Angiogram (Magnetic Resonance Angiogram - MRA) : This is a special MRI scan that looks at blood vessels, similar to a CT angiogram.
The doctor will decide what treatment is best for you based on the information obtained from these tests. How do you treat these swollen blood vessels in your legs?
The risk of a ``Femoral Artery Aneurysm'' rupturing is relatively low (about 1% to 14%). Therefore, not everyone will need surgery right away . However, your doctor may recommend surgery to repair the aneurysm in the following cases:- If you have symptoms (e.g. pain, swelling, a blood clot).
- If the swelling bursts (this is an emergency and requires immediate surgery).
- If the swelling is getting bigger (the doctor will check it regularly).
- If the diameter of the bulge is larger than 2.5 centimeters (about an inch) .
To repair this bulge, doctors usually perform an `open surgery` . That is, they cut open the skin and look directly at the blood vessel. This is not the `laparoscopic` surgery that is often done through small incisions with a camera. The surgeon removes the swollen, weakened part of the blood vessel and replaces it with an artificial tube, called a `fabric graft` (a tube made of a special type of fabric). This is like cutting out a weak spot in a fire hose and replacing it with a new, stronger piece. Then blood flow can resume smoothly and without interruption.
What complications can occur after this surgery?
As with any surgery, there is a small chance of some complications after this femoral artery bypass grafting surgery. But doctors are very careful about these.- Infection : The surgical wound can fester and become infected.
- Bleeding : Bleeding may occur after surgery.
- Blood clots: Blood clots can form in the legs.
These are usually things that can be controlled. If you feel anything unusual, you should tell your doctor immediately. How long does it take to recover after this treatment?
After the surgery, you will need to stay in the hospital for about three to ten days. It may take a month or more to fully recover and return to normal activities. So, it is very important to follow the doctor's instructions exactly and to be patient during this time. What can I do to reduce this risk?
As we discussed earlier, the main cause of this `(Femoral Artery Aneurysm)` is `(Atherosclerosis)`, a buildup of fat in the blood vessels. So, controlling it can reduce the risk of these aneurysms.- Control your cholesterol levels and blood pressure . Take the medications prescribed by your doctor.
- Exercise regularly . Even something as simple as walking for 30 minutes a day is good.
- Eat a healthy, low-fat diet . Eat more fruits, vegetables, and fiber-rich foods.
- If you smoke, stop it completely . Stop using tobacco products too. This is very important.
- For some people, in addition to these lifestyle changes, the doctor may also recommend continuing to take cholesterol-lowering drugs.
If I have bloating like this, what should I expect?
This `(Femoral Artery Aneurysm)` will not go away on its own without treatment. If your doctor tells you that you have one, he will check it regularly (tell you to come for `follow-up`). That is, he will do tests like `(Ultrasound scan)` at certain intervals to see if the swelling is getting bigger or if there are other problems. Based on that, he will decide whether surgery is needed or whether to wait a little longer. The results of these surgeries are usually very good. The risk of death at the time of surgery is very low, between 1% and 5%. Even five years after the surgery, about 85% of the repaired blood vessels are still functioning well, without any problems with blood flow. This is really good news. How can I take care of myself?
If you have a `(Femoral Artery Aneurysm)` and have had surgery, or are being monitored by a doctor without surgery, you will need to have your arteries checked regularly by a doctor for the rest of your life. This regular check-up can help detect any new aneurysms before they get bigger and burst. If you smoke, it can make these aneurysms bigger. Therefore, your doctor will definitely advise you to stop smoking. Also, follow the instructions given to control your cholesterol and blood pressure exactly. When should I go to emergency care?
If your leg or foot suddenly shows one or more of these symptoms, you should go to a hospital emergency room immediately, without delay :- If the leg becomes weak or feels lifeless.
- If the leg suddenly swells .
- If you are experiencing unbearable pain .
- If your leg is numb .
- If your leg feels colder than the other leg when you touch it.
- If the leg has turned pale or has changed color.
These symptoms indicate a serious problem with the blood flow to the leg, which could mean that the swelling could be causing a blood clot or the swelling could be bursting. Therefore, getting treatment quickly without wasting time can be life-saving. What questions should I ask the doctor?
If you have any questions or concerns about this condition, don't hesitate to ask your doctor. For example, you can ask questions like these:- "Doctor, what exactly is causing this swelling in my veins?"
- "Do I really need surgery for this? Aren't there other treatments?"
- "Could I have more swelling like this in other parts of my body?"
- "Can you give me some advice on foods that will help lower my cholesterol levels?"
It is very important to ask questions like these to gain a better understanding of your situation. What is the difference between `Femoral Artery Aneurysm` and `Pseudoaneurysm`?
Sometimes you will also hear the term `(Pseudoaneurysm)`. This means "false bulge". This `(Pseudoaneurysm)` is more common than the real `(Femoral Artery Aneurysm)` that we have been talking about. Usually, a `(Pseudoaneurysm)` is formed after a medical procedure on your blood vessel (for example, when an `(angiogram)` is done or a `(catheter)` is inserted), and the wall of that blood vessel is slightly damaged, and some blood leaks out and collects around the vein, forming a lump. The main difference is that in a real `(aneurysm)`, all the layers of the blood vessel wall stretch and bulge. But in a `(pseudoaneurysm)`, that does not happen, it is a collection of blood that leaks out through a hole in the blood vessel wall. What is the message we want to take home from this story?
So, although the femoral artery aneurysm we talked about at length is very rare, it is very important for you and your family to be aware of it.- This can often be asymptomatic .
- If you have risk factors (high blood pressure, cholesterol, smoking, family history), seek medical advice .
- If your doctor finds that you have one, don't panic. There are effective treatments that can be used to remove it, even surgically, before it bursts .
- Meeting with a doctor who has experience treating these types of conditions will be a great relief for you.
- Always take care of your health, live a healthy lifestyle, and follow your doctor's instructions exactly.Then you can avoid many health problems like this and stay healthy.
If you have any further questions, be sure to talk to your family doctor or a specialist.
