By obliterating endarteritis mean systemic chronic inflammatory disease that affects the small arteries and superficial veins of the lower extremities.The disease is fairly common, and represents one of the most frequent causes of amputations in young men.The disease is difficult, resulting in difficult struggle with it, but in recent years has revealed information about the pathogenesis of vascular lesions have developed new methods of exposure to the disease.Consider the causes and treatment of obliterating endarteritis.
reasons obliterating endarteritis
exact cause of obliterating endarteritis not established.The overwhelming majority of researchers are inclined to the autoimmune nature of the disease.Often patients with detectable changes in the immune system.
Development of the disease contribute to the following factors:
- presence of mental stress, stress;
- frequent hypothermia feet;
- alcohol abuse;
- poisoning by certain poisons in the chronic stage;
- excessive consumption of fatty foods.
symptoms of obliterating endarteritis
The connection of the symptoms of thromboangiitis obliterans and chronic arterial insufficiency of the lower limbs.From patients with complaints to the appearance of fatigue in the legs, increased sensitivity to low temperature, the occurrence of numbness, seizures, pain when walking or at rest, trophic disorders in the form of ulcers in the feet and toes, gangrene or necrosis.The differential diagnosis is carried out, especially with vascular lesions in diabetes, atherosclerosis obliterans.
for diseases characterized by undulating course, which marks the change of periods of exacerbation more or less stable improvement.
as the main specific symptoms, in which is possible to detect obliterating endarteritis, advocates the emergence of intermittent claudication: severe pain that occurs in the calf muscles, due to which the patient slows down and stops at regular intervals way.The pain disappears after a short rest.In addition, the patients felt heaviness in the legs, sweating, feeling that creeps crawling on it.External symptoms of the disease in the initial stages is pallor and coldness of the affected limb portion, in advanced cases - the emergence of non-healing venous ulcers.There weakening or disappearance of ripple on the main arteries of the lower limbs.
Diagnostics obliterating endarteritis
doctor can be performed at diagnosis of obliterating endarteritis initial examination of the patient due to the clearly defined symptoms.To confirm the diagnosis, provides for the application:
- Doppler ultrasound;
- arterial angiography.
Treatment of obliterating endarteritis
If the disease is detected at an early stage, treatment is usually conservative, which employ drugs (antiplatelet agents, antispasmodics, antihistamines drugs, vitamins), held physiotherapy.In the early stages have a good therapeutic effect diadynamic currents, barotherapy, diathermy.If the disease is detected late, in case of failure of medical treatment provided surgery.If it affects a small portion of the artery, it is removed.If the pathological process of land affected by more than 15 cm, it is necessary to bypass surgery or prosthetic arteries.The most common surgery for occlusive disease - aortofemoral bypass.A good effect has sympathectomy operation in which intersect the sympathetic nerve trunks, so that docked vasospasm.If gangrene develops, then amputated the affected segment or the entire limb.
If treatment is not started on time, and in case of impossibility to remove provoking factors, the disease has a poor prognosis.Inevitably developed gangrene and lost a limb.If treated early, and it is complex, it is possible to significantly slow the progression of, prevent loss of the limb.
