Atherosclerosis of the lower limb vessels: diagnosis, prognosis, and treatment methods

Definition and mechanism of disease development

Atherosclerosis of the lower extremities is a chronic disease of the arteries, characterized by the formation of atherosclerotic plaques, which leads to narrowing or blockage of the vascular lumen. This process is usually caused by the deposition of cholesterol and other substances on the inner wall of the arteries, resulting in the formation of plaques that reduce the lumen of the vessels and disrupt normal blood supply to the tissues. With prolonged progression of atherosclerosis, ischemia of the lower extremities may develop, leading to decreased functionality and reduced quality of life for patients.

Risk factors for the development of atherosclerosis

Atherosclerosis of the lower limb vessels is a pathological condition characterized by the formation of fatty deposits and atherosclerotic plaques in the arteries, caused by dyslipidemia and chronic inflammation. The main risk factors for the development of this disease are smoking, diabetes mellitus, arterial hypertension, hypercholesterolemia, as well as hereditary predisposition. Additionally, older age, low physical activity, improper nutrition, and excess weight are also considered significant factors contributing to the onset and progression of atherosclerosis of the lower limb vessels.

  • Smoking: Nicotine and other harmful substances in tobacco smoke contribute to damage to the vascular wall and the development of atherosclerosis.
  • Diabetes mellitus: High blood sugar levels increase the risk of vessel damage and the formation of fat deposits.
  • Arterial hypertension: High blood pressure increases the load on the vessels, contributing to the development of atherosclerosis.
  • Hypercholesterolemia: Elevated cholesterol levels in the blood can lead to the formation of atherosclerotic plaques.
  • Hereditary predisposition: Genetic factors can affect the body’s ability to process fats and cholesterol, increasing the risk of developing atherosclerosis.

Clinical manifestations of atherosclerosis of the lower extremities

Atherosclerosis of the lower limb vessels can manifest with various clinical symptoms, including chronic ischemia, pain in the muscles while walking (intermittent claudication), moderate or severe weakness in the legs. Pain may occur after walking a certain distance and decrease at rest (intermittent claudication). Patients may also experience redness, tenderness, and swelling of the limbs, flexibility of the angiotrophic legs, and evidence of baldness and muscle atrophy may also be observed.

  • Intimate claudication: a symptom of classic atherosclerosis of the lower extremities, manifested in muscle pain while walking, which decreases at rest.
  • Intermittent claudication: exacerbation of intimate claudication, characterized by pain while walking a certain distance, with pain ceasing when physical activity stops.
  • Redness and swelling of the extremities: possible signs of chronic ischemia of the lower extremities, manifesting as changes in color and swelling of tissues.
  • Baldness and muscle atrophy: consequences of chronic circulatory disorders, which can lead to a decrease in muscle volume and loss of hair coverage.
  • Flexibility of angioopathic legs: in lower extremity atherosclerosis, a decrease in joint mobility and certain changes in the shape of the legs may be observed.

Expert opinion on the therapy of atherosclerosis of the lower limbs

Experts’ opinions on the therapy for atherosclerosis of the lower limb vessels emphasize the need for a comprehensive approach to the treatment of this condition. First, a detailed diagnosis is carried out, including a clinical examination, laboratory tests, and instrumental studies such as angiography and duplex scanning of the vessels. Based on the information obtained, an individualized treatment plan is prescribed, which includes medication therapy, surgical methods, and lifestyle modifications.

Experts recommend actively addressing risk factors such as smoking, hypercholesterolemia, arterial hypertension, and diabetes. To improve the disease prognosis, it is essential to monitor physical activity levels, follow dietary recommendations, and regularly undergo medical examinations and consultations. Medication treatment is aimed at lowering cholesterol levels, blood pressure, improving blood flow, and preventing possible complications such as vascular thrombosis.

Methods for diagnosing atherosclerosis of the lower limbs

Diagnosis of atherosclerosis of the lower limb vessels includes various examination methods for an accurate assessment of the vessel condition and the degree of damage. One of the main diagnostic methods is duplex scanning (ultrasound Doppler examination), which allows visualizing blood flow in the vessels and determining the presence of stenoses and thrombi. In addition, magnetic resonance angiography and computed tomography with contrast agent (CTA) are used for a more detailed and accurate study of blood flow and the structure of the lower limb vessels.

  • Duplex scanning of blood vessels: a method based on ultrasound technology that allows for the assessment of blood flow and the degree of artery damage.
  • Magnetic resonance angiography: an imaging method that uses a magnetic field and radio waves to create detailed images of the blood vessel structure.
  • Computed tomography with contrast agent (CTA): a method that allows for the acquisition of three-dimensional images of blood vessels using X-ray radiation and a contrast agent.
  • Angiography of blood vessels: a procedure in which a radiopaque substance is injected into the vessels to visualize and study their structure on X-ray images.
  • Artery catheterization: a method that allows measuring blood pressure in the arteries and assessing their patency using special catheters.

Methods for treating atherosclerosis of the lower extremities

The treatment of atherosclerosis of the lower extremity vessels includes conservative and surgical methods. Among conservative methods, medication therapy is effectively used, which includes antiplatelet agents, statins, drugs that improve microcirculation, as well as the use of anticoagulants. Physiotherapy is often used to improve vascular blood flow and reduce pain. In cases of severe vascular damage, surgical intervention may be required, such as angioplasty, bypass surgery, or endarterectomy.

  • Medication therapy: includes the use of antiplatelet agents, statins, and drugs that improve microcirculation.
  • Therapeutic exercise: exercises aimed at strengthening muscles, improving blood circulation, and vessel patency.
  • Diet therapy: adherence to a healthy diet with limits on fatty and high-calorie foods rich in cholesterol.
  • Surgical treatment: in cases of severe impairment, angioplasty, bypass surgery, or endarterectomy may be applied.
  • Prevention: regular check-ups with a doctor, maintaining a healthy lifestyle, quitting smoking, and moderate physical activity will help prevent disease progression.

Measures for the prevention of atherosclerosis of the lower extremities

Prevention of atherosclerosis of the lower limb vessels plays an important role in maintaining vascular health. The main measures include a healthy lifestyle, such as regular physical exercise, proper nutrition with limits on fats and sugars, quitting smoking, and moderate alcohol consumption. Monitoring cholesterol levels, blood pressure, and maintaining a normal weight are also important aspects of preventing atherosclerosis of the lower limbs. It is important to timely identify and treat other risk factors, such as diabetes and hypertension, to prevent the development of atherosclerosis and its complications.

  • Maintaining a healthy lifestyle, including regular physical exercise to strengthen blood vessels and improve overall health.
  • A balanced diet rich in fruits, vegetables, grains, fish, nuts, and seeds, as well as limiting the intake of animal fats and trans fats.
  • Quitting smoking and minimizing alcohol consumption to reduce the risk of developing atherosclerosis and its complications.
  • Regular monitoring of cholesterol levels and blood pressure for timely identification and management of risk factors.
  • Maintaining a normal weight and monitoring blood glucose levels to prevent metabolic disorders such as type 2 diabetes, which can contribute to the development of atherosclerosis.

Amazing facts about the development of atherosclerosis of the lower limbs

An interesting fact about the development of atherosclerosis of the lower extremities is that the process of this disease begins long before clinical symptoms appear. This means that atherosclerosis can continue unnoticed and progress for a long time before becoming symptomatic. Furthermore, some risk factors, such as smoking, diabetes, and hypercholesterolemia, can significantly accelerate the development of atherosclerosis and its complications.

Another interesting fact is that atherosclerosis of the lower extremities can often go undiagnosed because its symptoms may be confused with other diseases or simply associated with physical fatigue or aging. Therefore, it is important to pay attention to any signs of changes in the blood vessels and take preventive measures in a timely manner to prevent the progression of atherosclerosis and its associated complications.
