Lymphangiectasia

Lymphangiectasia - enlargement of the lymph vessels in the extremities, in the thoracic and abdominal cavities due to circulatory disorders, diseases of the lymph nodes. If lymphangiectasia lymphatic vessels dilated, twisted, swollen organ.
Treatment: on a limb - bondage, in a limited area of skin excision.

Lymphangiectasia (lymph + GK. angeion - vessel and ektasis - extension - the extension of the lymphatic vessels; it may be primary or secondary. Primary lymphangiectasia are rare, mainly in the lung (congenital pulmonary L. or pulmonary lymphangiectasia cysts). Regarding the nature of pulmonary L. there are three points of view: 1) malformation of the lymphatic system, lung, 2) malformation of the connective tissue framework of the lung and 3) poltareva obliteration ways of lymph drainage from the lungs.
The surface of the lung tissue looks kinda grainy. Under the microscope is determined by the abundance interlobular, peribronchial and perivascular lymph cysts. The disease is accompanied by cyanosis and pulmonary-cardiac insufficiency. At one-way process may surgical treatment.
Primary lymphangiectasia in the extremities accompanied the so-called primary lymphangitis, based hypoplasia or aplasia of the lymphatic vessels; eventually develops lymphoedema raesk (see Elephantiasis). Postmortem: sharp intimal thickening of lymphatic vessels sclerosis media and adventitia, which explains the term "obliterating lymphangiectasia".
Secondary lymphangiectasia meet often associated with swelling and lymphostasis. Their appearance explain the close relationship wall lymphatic capillaries surrounding connective tissue fibers. Edema fluid expands and shrinks these fibers from each other, resulting in gaps of lymphatic capillaries remain open. A similar mechanism L. observed and inflammation. The enlargement of the lymph vessels lead to lymph circulation insufficiency and break the wall of lymphatic vessel with a picture of limforeei.
