myxoma - a benign tumor, which is formed from connective tissue.At the present time, distinguish the true (primary) and false (secondary) myxoma.True, according to most experts, there are residues of the mature (that is reincarnated into an embryonic) or mucosal (embryonic) connective tissue.With regard to the second, they are the result of diseases such as: chondroma, lipoma, fibroma, etc.
myxoma can be localized to any organ, but most often they are formed in the intramuscular and subcutaneous tissue, on the limbs along the nerve trunks, the walls of the bladder, in the mesentery and the navel.Although the disease is a benign tumor, it is very often after surgery recur.
Grossly the tumor appears as a node (at times, consists of several components, fused to one another), has a gelatinous consistency and lobular structure.In the secti
myxoma are richly vascularized;sometimes they are islets fat, cartilage, and fibrous tissue, which occur due to differentiation of tumor cells.Symptoms and clinical manifestations depend on the localization of tumors.myxoma treatment - surgery alone.
Three-quarters of these tumors occur in the left atrium (the heart is a camera that receives oxygen-rich blood).Atrial myxoma often have leg (it looks like a balloon on a string) that, as a rule, lead to their displacement.They may turn out to be far away from the mitral valve.Because of such movements myxoma often overlaps, and then again opens the valve hole, leading to periodic disturbances of blood flow.After a temporary overlap of valve opening, again comes the restoration of blood flow.
Sudden shortness of breath, fainting and swelling of the lung develops in the vertical position of the patient as well as the effect of gravity shifts to the mix atrial valve opening.If the patient immediately receives the horizontal position, the symptoms immediately starts to decrease.
times, myxoma particles or clots that form on its surface can break off and travel through the bloodstream to other organs some blocking blood vessels.The clinical picture depends on what kind of vessel blockage succumbed.For example, blockage of the vessels in the lungs can cause pulmonary infarction, and vascular occlusion in the brain - a stroke.Embolic mesenteric vessels resulting in occlusion of mesenteric vessels.Thromboembolism retinal arteries may cause transient or permanent vision loss.There are also situations where thromboembolism with heart myxoma ends sudden death.
There are many different symptoms that accompany mix atrium.These include:
Today, there are many factors, which are the main instigators of formation of myxoma.Some of them are:
Diagnose a tumor with the help of an electrocardiogram, echocardiography, coronary angiography, CT or MRI, chest X-ray, as well as cardiac catheterization and biopsy.
differential diagnosis of atrial myxoma is performed with infective endocarditis, constrictive pericarditis, Ebstein's anomaly, tricuspid and mitral heart defects combined, connective tissue diseases, malignant tumors of the heart, and so on.
With regard to the treatment of myxoma, it is to remove the intracavitary tumor surgically.Since there is a high risk of thromboembolic complications, as well as sudden death, all patients (after diagnosis) is assigned to immediate operation.
If we talk about conservative treatment of myxoma of the heart, the resort to it only in terms of preoperative preparation.
risk of sudden death in patients with atrial myxoma is 30%.Life expectancy in the normal course of the disease does not exceed two years (since the emergence of the first symptoms).The death of patients is usually associated with occlusion of the heart valves or holes tumor embolism.
After surgery, most patients feel well, because there comes a full recovery.Postoperative recurrence of atrial myxoma are very rare (1-2% of cases).
When these symptoms each patient is required to address urgently to the attending doctor:
