Chronic lower limb ischemia (CLLI) is a condition in which blood flow in the arteries of the lower extremities is impaired, leading to insufficient delivery of oxygen and nutrients to tissues. The most common cause is arterial atherosclerosis. Treatment is aimed at restoring blood flow, reducing symptoms, and preventing complications such as gangrene.
Main goals of treatment
- Restoration of tissue perfusion.
- Reduction of pain syndrome.
- Prevention of trophic ulcers and tissue necrosis.
- Improvement of the patient’s quality of life.
Approaches to the treatment of CLLI in Belarus
- Lifestyle modification. Elimination of risk factors.
- Pharmacological therapy. To improve blood circulation and prevent thrombosis.
- Physiotherapy and non-pharmacological methods. Increasing exercise tolerance.
- Endovascular and surgical treatment. Vascular reconstruction to restore blood flow.
Lifestyle modification
Risk factor control
- Smoking cessation. Smoking accelerates the progression of atherosclerosis.
- Physical activity. Regular moderate exercise (e.g., walking) improves peripheral circulation.
- Diet. Limitation of fats, sugar, and salt. Inclusion of foods rich in fiber and omega-3 fatty acids (fish, nuts).
- Body weight control. Weight reduction in patients with obesity.
- Stress management. Reducing stress helps improve overall vascular health.
Pharmacological therapy
Comprehensive use of specialized medications.
Physiotherapy and non-pharmacological methods
- Supervised walking programs. Regular walking until the onset of leg pain stimulates the development of collateral circulation.
- Hyperbaric oxygen therapy (HBOT). Improves tissue oxygenation and reduces the risk of necrosis.
- Electrical stimulation. Enhances blood circulation and metabolic processes in tissues.
- Negative pressure wound therapy (VAC therapy). Used in the treatment of trophic ulcers.
Endovascular and surgical treatment
When pharmacological therapy is ineffective, interventional procedures are used to restore blood flow.
Endovascular methods
- Angioplasty. Balloon catheter dilation of the narrowed arterial segment.
- Stenting. Placement of a metallic stent to maintain vessel patency.
- Thrombolysis. Administration of drugs to dissolve thrombi.
Surgical methods
- Bypass surgery. Creation of an alternative pathway for blood flow using autologous vessels or synthetic grafts.
- Endarterectomy. Removal of atherosclerotic plaques from the arterial wall.
- Amputation. Performed only in cases of irreversible necrosis not amenable to treatment.
Prognosis and prevention
- The prognosis depends on the stage of CLLI and the effectiveness of therapy.
- With early diagnosis and adequate treatment, significant improvement and limb preservation are possible.
Preventive measures
- Control of risk factors (hypertension, diabetes mellitus, hypercholesterolemia).
- Regular physical activity.
- Timely medical consultation at the first signs of ischemia (intermittent claudication, cold extremities).
- Smoking cessation.
Management of chronic lower limb ischemia requires a comprehensive approach that includes lifestyle modification, pharmacological therapy, and, when necessary, surgical intervention. Early detection and effective control of risk factors help prevent severe complications, improve quality of life, and preserve limb function. Regular follow-up and adherence to medical recommendations are key to successful treatment.
In Belarus, treatment of chronic lower limb ischemia is carried out in specialized medical centers using modern diagnostic and therapeutic methods.
