Extremity ischaemia (Ischemia) - Description and treatment
Do you feel the sensation of cold limbs? Does pain make you take breaks while walking and with time wake you up from sleep? Then you are probably affected by ischemia. It may result in tissue necrosis and creation of ulcers. In final stages, the limb might be in danger of amputation.
Do not use this or any other article on the internet to diagnose yourself. Only physicians can correctly diagnose patients. Do not postpone seeing your physician to resolve your health issues in time.
Characteristics of Extremity Ischemia and its Causes
Extremity Ischemia causes an insufficient supply of oxygen and nutrients to the muscles and tissues. Ischaemia has the effect where limbs are not properly blood perfused, which, along with other factors and tendencies, leads to frequent necrosis. This results in a variety of trophic changes, which may lead to amputation of a limb.
With lower extremity ischemia, the disease affects arteries in legs and causes a narrowing or occlusion of the arteries.
The most common cause of narrowing or occlusion is atherosclerosis (hardening of the arteries), thrombus (blood clot), Buerger’s disease, and vasoconstriction of arteries.
Upper extremity ischemia is far less common than the lower extremity one; Raynaud’s phenomenon, a disease often called “white fingers,” is a common form.
Acute extremity ischemia is symptomized by sudden and severe pain in the limb, paleness of the limb with no swelling, impalpable pulse beyond the occlusion of the artery, impossibility to move the limb and altered sensation.
The main risk factors in developing the disease are:
- lack of exercise,
- advanced age,
- psychological stress,
- high level of cholesterol,
- high blood pressure,
- diabetes and others.
Extremity Ischemia Treatment – Rid yourself of the Pain
This disease requires specialised vascular examination and timely start of treatment based on the stage and location of the disease. The main goal is to improve arterial blood circulation and to avoid amputation. Vascular surgery plays an important role. Its goal is to attain sufficient blood perfusion in the injured limb and to make the bloodstream unobstructed (angioplasty, bypass…).
From the long-term point of view, adjustments to the lifestyle and elimination of risk factors like smoking, stress, weight reduction and managing diabetes are important.
The main goal of pharmacological treatment is to reduce platelet aggregation and creation of blood clots (antiaggregation therapy). Some drugs can directly affect arteries and cause their dilation (vasodilation drug and infusion therapy).
Acute extremity ischemia requires immobilization, covering and bracing the limb, administering heparin, analgesics and calming the patient.
In cases where there is a defect on the limb, wound healing tools and methods are utilised. Moist wound healing and physical therapy are some of those tools.
Regular physical activity and rehabilitation is of importance with the goal of improving microcirculation – to affect microangiopathy – dilating capillaries and pre-capillaries, and improving transfer of oxygenated blood and nutrients directly to working muscles and tissues.
Within the rehabilitation treatment low-frequency pulsed magnetic therapy has its place in treating some symptoms of limb ischaemia as it utilises the vasodilating, analgesic and healing effects with the support of anti-inflammatory effect. It does not affect dilation of medium and large arteries -the above mention antiaggregation infusion or surgical treatment is necessary here.
Magnetic therapy significantly improves microcirculation of oxygenated blood in the affected areas of the limb through the vasodilating effect targeting capillaries and pre-capillaries. It accelerates healing of damaged tissue and helps bring general relief.
Home applications are a huge convenience which allows the patient to continue intensive rehabilitation at home, out of hospital facilities.
The possibility of a secondary, long-term promotion of blood perfusion through vasodilation from the first signs of the disease is a benefit.
Patented 3D Biomag pulsed therapy. How does it work?
The basic principle of 3D Biomag magnetic therapy is generating electromagnetic pulses. The generated pulses can penetrate through layers of clothing and even body tissues to the place of application. These pulses have specially developed biotropic parameters (e.g. frequency, profile, intensity), thanks to which the pulsed magnetotherapy affects various health conditions.
The term pulse magnetic therapy is most commonly used for physiotherapy using the principle of electromagnetic pulses. The abbreviation PEMF is used in order to be concise.
Patented 3D Biomag technology ensures more precise and uninterrupted pulse profiles, enhances output, and allows pulses to come from various angles.
Pulsed magnetic therapy is not meant to treat limb ischaemia itself. Such treatment can only be recommended by a physician. Magnetic therapy application is used on symptoms of limb ischaemia, such as pain, reduced blood perfusion and inflammation.
