As angiodysplasia ( altgriech. Ἀγγεῖον ( angeion ) vessel δυσ- ( dys ) 'mis-, un-', πλάσσειν ( plassein ) form of πλάσσω, shapes) is called vascular malformations of arteries , veins or lymphatic vessels , which in enormous complexity and diversity can occur. As a synonym, they are also known as vascular dysplasias .

Hamburg classification

In the past one could only describe these clinical pictures and their pathomorphology could not be recorded. Depending on the vessel, the malformations were given numerous syndrome names , sometimes for the same malformation. The assignment of a clinical picture to one of these syndromes is not always successful and overlaps are possible. The Hamburg classification developed in 1988 avoids the syndrome terms and tries to describe angiodysplasia according to its anatomical and functional changes. On the one hand, a distinction is made between two forms, truncular and extratruncular, in which the disorders in the embryonic development phases are taken into account.

Hamburg Classification of Angiodysplasias
Art Truncular form Extra-truncular shape
Mainly arterial defects Aplasia (lack of attachment), obstruction (narrowing), dilation (widening) Infiltrating or circumscribed
Mainly venous defects Aplasia, obstruction, dilation Infiltrating or circumscribed
Mainly lymphatic defects Aplasia, obstruction, dilation Infiltrating or circumscribed
Mainly arteriovenous defects Deep and superficial AV fistulas Infiltrating or circumscribed
Combined errors Arterial and venous and lymphatic with and without AV fistula Infiltrating or circumscribed hemolymphatic

Syndromes

Developmental Venous Anomaly

The Developmental Venous Anomaly (DVA) is a benign, venous malformation in the brain . The anomaly consists of a bundle of dilated, medullary veins that converge on a large-caliber central drainage vein.

Naevus flammeus

The fire mark or nevus flammeus is a benign skin lesion. The fire mark is based on a congenital malformation. The fine blood vessels that run beneath the epidermis are abnormally enlarged and tend to grow . The stain of fire can in some cases be an indication of another disease. Up to 30 syndromes have so far been linked to the occurrence of a fire mark:

Sturge Weber Syndrome

Sturge-Weber syndrome is a congenital progressive disease belonging to the group of neurocutaneous phacomatoses . It is characterized by hollow benign vascular tumors ( angiomas ) in the facial area, in the area of ​​the meninges , in the area of ​​the ipsilateral soft meninges ( leptomeninx ) and the choroid of the eye ( choroid ). Affected children can suffer from epileptic seizures , glaucoma and mental retardation .

Klippel-Trénaunay-Weber syndrome

The Klippel-Trénaunay-Weber syndrome is a malformation syndrome of the vessels, which is associated with a large nevus flammeus , lymphangioma , which is sometimes accompanied by gigantic growth of the trunk or extremities . In addition, causal malformations of the deep blood and lymphatic system can occur.

Maffucci syndrome

The syndrome is characterized by enchondromatosis (multiple benign cartilage tumors ) and deep cavernous hemangiomas and lymphangiomas of the skin and internal organs.

Hemangioma

Hemangioma

A hemangioma (blood sponge ) is an embryonic tumor with endothelial proliferation and secondary formation of vascular lumen. A distinction is made between capillary hemangioma, cavernous hemangioma, grape or berry-shaped hemangioma, sclerosing hemangioma, hemangioma planotuberosum, hemangioma of the eye socket and hemangioma of the liver .

Kasabach-Merritt syndrome

In Kasabach-Merritt syndrome, benign, cavernous and large to huge hemangiomas develop. It is more likely to occur in benign tufted angioma (synonym: Angioblastoma of Nakagawa) and in Kaposi-like malignant epithelioid hemangioendothelioma .

Pyogenic granuloma

Pyogenic granuloma is a benign vascular skin tumor belonging to the group of hemangiomas. It is an exophytic vascular proliferation .

Vascular malformation

Osler's disease

A vascular malformation (vascular malformation) is a malformation of one or more blood or lymph vessels. The vascular malformations include the arteriovenous malformations (AV malformations), the cavernomas (venous malformations), and lymphatic malformations . A special form of a lymphangioma is the hygroma colli . Also the Gorham's disease is associated with lymphangioma in conjunction. Malformations are mostly congenital, but show an increase in size over the course of life. Osler's disease is one of the capillary malformations in the digestive tract .

Osler's disease

Osler's disease is an autosomal dominant inherited disease in which there is pathological dilatation of blood vessels. These so-called telangiectasias can occur anywhere, but are particularly found in the nose (leading symptom nosebleed ), mouth , face and the mucous membranes of the gastrointestinal tract, but they can also occur in the lungs , liver and brain, which - especially from the age of 40 - internal bleeding can occur, which can even have life-threatening effects.

Heyde syndrome

Coagulation of angiodysplasia of the colon in Heyde syndrome

Heyde syndrome consists of the combination of acquired aortic valve stenosis and bleeding from malformed blood vessels in the ascending part of the colon . The anemia caused by the bleeding is also considered part of the syndrome.

Kommerell's diverticulum

Kommerell's diverticulum is a sac-like enlargement or protuberance of the aortic arch or the descending main aorta (aorta descending) in the case of a right subclavian artery ( arteria subclavia dextra) emerging from the aorta .

Hippel-Lindau disease

Hippel-Lindau's disease is a rare, hereditary tumor disease from the so-called phakomatoses . The patients develop benign, tumor-like tissue changes ( angiomas ) primarily in the area of ​​the retina of the eye and the cerebellum . In the central nervous system , the brain stem and spinal cord , and rarely the cerebrum, can also be affected. It is characteristic that tumors develop consisting of blood vessels. Many patients also have tissue changes in the kidney ( renal cell carcinoma ), adrenal gland ( pheochromocytoma ), and pancreas . In men, the epididymis can be affected.
