From this article you will learn: what is obliterating atherosclerosis of the vessels of the lower extremities, what are its stages. What are the consequences of the disease, the methods of diagnosis and treatment.
The reasons for the pathology
Obliterating diseases are those in which the lumen of the vessel narrows, until complete blockage occurs. The most common disease of this group is atherosclerosis.
With obliterating atherosclerosis of the lower limbs, cholesterol plaques are deposited in the arteries of the legs. If you do not start treatment on time, pathology can lead to disability due to vascular disruption.
If there are signs of atherosclerosis, contact your GP immediately, who will refer you to an angiologist, a vascular specialist.
Completely cure the disease with the help of conservative therapy is impossible. But the treatment will help avoid dangerous complications and improve your health.
Causes of obliterating atherosclerosis
The disease appears due to a metabolic disorder.
Factors that contribute to the development of the disease:
- heredity,
- malnutrition,
- sedentary lifestyle,
- smoking and alcoholism,
- age over 40 years.
If someone from your family had atherosclerosis, stick to a diet and avoid bad habits, since you have a particularly high risk of getting sick.
Four stages of pathology
Obliterating atherosclerosis proceeds in several stages:
- Preclinical atherosclerosis. At this stage, the symptoms are not yet apparent. Disease in the first stage can be detected only with a special examination of the vessels. On the intima( internal wall) of the arteries there are small fat deposits in the form of strips and spots.
- Slightly pronounced. On the walls of the vessels more frequent spots of cholesterol are found. At this stage, the first symptoms begin to appear. If you start treatment at this stage, you can avoid complications and prevent further development of the disease.
- Strong. On the intima of the arteries there are significant changes. Lipid deposits take the form of plaques, begin to narrow the lumen of the vessels. At this stage, there are already all the symptoms of the disease, which in no case can not be ignored. Already at this stage of development pathology can cause dangerous to health complications of blood circulation.
- Very pronounced. At this stage, the work of the vessels is completely disrupted. The pieces of atherosclerotic plaques come off and circulate inside the arteries. Aneurysms( pathological dilations) also appear on the vessels, because of which the artery may burst. In addition, the plaque can completely clog the vessel. Because of all this, the blood supply of the lower extremities is severely impaired.
Symptoms of
First signs( second stage of the disease)
- Begin to freeze feet;
- feet often become numb;
- swelling of the feet;
- if the disease struck one leg, it is always colder than healthy;
- there are pain in the legs after a long walk.
These manifestations appear in the second stage. At this stage of atherosclerosis, a person can pass 1000-1500 meters without pain.
People often do not appreciate symptoms such as freezing, periodic numbness, pain when walking for long distances. And in vain! After starting the treatment in the second stage of the pathology, you can prevent complications 100%.
Symptoms that appear on stage 3 of
- Nails grow more slowly than before;
- , the hair begins to fall on the feet;
- pain can occur spontaneously both during the day and at night;
- pains appear after walking for short distances( 250-900 m).
All this arises because of insufficient blood supply to the tissues of the legs. If you do not start treatment, the disease will soon go to stage 4 - the most dangerous.
Manifestations of the 4th stage
When a person has a stage 4 obliterating atherosclerosis of the legs, he can not pass and 50 meters without pain. For such patients, an unbearable task becomes even a shopping trip, and sometimes just going into the yard, as climbing and descending the stairs turns into torture. Often, patients with stage 4 disease can only move around the house. And as complications develop, they stop getting up at all.
At this stage, the treatment of the disease obliterating atherosclerosis of the lower extremities often becomes impotent, it can only lighten the symptoms for a while and prevent further complications such as:
- darkening of the skin on the legs;
- ulcers;
- gangrene( this complication requires limb amputation).
Diagnosis of obliterating atherosclerosis
Several diagnostic procedures must be performed to identify a patient.
1. Initial inspection of
A doctor examines the patient's symptoms, his medical record( previous illnesses), measures blood pressure in his hands and feet, hears a ripple in the arteries of the lower extremities.
2. Duplex scanning of the vessels of the legs
This method allows you to assess the state of the arteries. With duplex scanning, the doctor can look at the shape of the vessels, find out the blood flow velocity over them.
3. Peripheral arteriography
This is an examination of the arteries of the legs using an X-ray machine. Before the examination, the patient is given a contrast agent. If the patient is allergic to it, the procedure is contraindicated.
Peripheral arteriography can detect aneurysms, blockage of blood vessels. Typically, doctors prescribe one of the methods to choose from: duplex scanning or arteriography. Preference is given to the first procedure, since it does not require the introduction of a contrast agent and allows a more detailed assessment of the circulation in the legs.
Procedure for peripheral arteriography 4. MR-angiography
This is an examination of the arteries using an MRI device. MR angiography in detail shows the state of the vessels and allows to reveal even small pathological changes in the structure of blood vessels and in the circulation. This procedure is prescribed if the final diagnosis was not possible after duplex scanning or arteriography( usually treatment is prescribed after one of these procedures).
Treatment of
The disease can be cured completely only with the help of vascular prosthetics. But such a radical method is required only at 3-4 stages: 1-2 intake of drugs that prevent further deposition of plaques and relieve unpleasant symptoms of atherosclerosis.
Conservative treatment( medicines)
They can get by in the early stages of the disease( first and second).With the help of medications you can reduce symptoms, improve the quality of life of the patient and prevent further development of the disease. Drug treatment is also needed after the operation. Take medication will have a constant throughout life.
| Drug group | Effect | Examples |
|---|---|---|
| Statins | Regulates the cholesterol content in the blood. | Fluvastatin, Rosuvastatin |
| Spasmolytics | Relieve spasm of vessels, dilate them, reduce blood pressure, improve blood circulation in small vessels of extremities | No-sppa, Galidor, Papaverin |
| Gangliablockers | Quaterone, Imhin, Dicaine | |
| Anticoagulants | Lower coagulability that prevents the formation of blood clots. | Heparin, Warfarin |
| Antiaggregants | Aspirin | |
| Painkillers | Relieve attacks of pain. Apply not constantly, but with the appearance of strong pain. | Novocain |
| Antioxidants | Protect the walls of blood vessels at the cellular level. | Ascorbic acid |
Drugs for obliterating atherosclerosis of the leg vessels Surgical treatment
The operation is prescribed at stages 3 and 4, when conservative therapy is already ineffective.
Surgical treatment of obliterating atherosclerosis can consist of stenting, shunting of the affected arteries or their replacement with artificial prostheses.
Angioplasty and stenting of the leg artery 
The operation can be either open or minimally invasive. Minimally invasive interventions are safer, but they are applied only if the affected area of the artery is small.
With gangrene or numerous ulcers, limb amputation is performed. Usually, this complication occurs only in 4 stages of atherosclerosis. It is necessary to do everything possible to cure the disease earlier, than such radical treatment is required.
Lifestyle and diet
If only to take medications, but continue to lead the same lifestyle, treatment will not have the desired positive effect.
First of all, if you have found obliterating atherosclerosis of the vessels of the lower extremities, you need to abandon bad habits.
First stop smoking. Nicotine narrows the blood vessels, which leads to an even greater deterioration of blood circulation in the legs.
Also do not allow yourself to drink a lot and often. Alcohol contributes to the formation of edema, which already appear due to impaired hemodynamics in atherosclerosis.
Part of the treatment is a special diet. Adhere to the rules of healthy eating: give up fatty, roast, smoked, hot, confectionery, fast food, baked goods, sweet, carbonated drinks. Limit the number of animal fats. Use butter not more than 20 g per day( and this should be a quality oil, and not margarine or spread, which contains trans fats).
Add more foods to the diet that lower cholesterol levels in the blood. Here is their list:
- citrus( grapefruits, lemons, oranges);
- avocado;
- grenades;
- apples;
- berries( cranberries, strawberries, currants, blueberries, grapes).
Folk remedies
Do not try to replace the traditional means of traditional treatment - this will lead to further development of the disease. Especially it concerns patients with atherosclerosis of 3 degrees and above - here without operational intervention it will not be possible to manage in any way. However, traditional medicine offers many tools that can be an excellent addition to traditional therapy and make treatment even more successful.
Before using any folk remedies consult with your doctor, as they may have contraindications.
Folk remedies for obliterating atherosclerosis of the vessels of the legs:
| Tool | Effect | Recipe |
|---|---|---|
| Hawthorn, cranberries and immortelle | Lower the cholesterol level. | Take 1 tbsp.l.hawthorn, 1 tbsp.l.immortelle and 1 tsp.cranberries, pour 1 liter of boiling water, insist 3 hours in a thermos, drink a glass a day. |
| Horse chestnut | Has anti-inflammatory and wound-healing effect, improves blood circulation and strengthens vessels | Take 20 g of peel or chestnut flowers, chop, pour 1 l of water, boil for half an hour in a water bath, strain, add boiling water to compensate the volume evaporated in the bath, takefor 1-2 tbsp.l. Per day. |
| Valerian root | Removes edemas | As it is hard to prepare roots yourself - it's hard, buy ready-made tincture of valerian, soak a piece of gauze in it for 2-3 hours. |
Infusions of these herbs help with the disease If you start to get treated on time, follow all the advice of doctors and supplement the therapy with folk medication, strictly adhere to the diet and get rid of bad habits, you can minimize the symptoms worsening life and get rid of the risk of ulcers and infectionblood.
