Low-flow malformations involve a single type of blood or lymph vessel, and are known as simple vascular malformations; high-flow malformations involve an artery. There are also malformations that are of mixed-flow involving more than one type of vessel, such as an arteriovenous malformation. [2] Low-flow vascular malformations include capillary ...
The estimated prevalence of vascular anomalies is 4.5%. [2] Vascular anomalies can occur throughout the whole body, but in 60% of patients they are localized in the head and neck region. [3] Vascular anomalies can present in various ways: when situated deep below the skin, they appear blue, and are often called cavernous.
An arteriovenous malformation (AVM) is an abnormal connection between arteries and veins, bypassing the capillary system. Usually congenital , this vascular anomaly is widely known because of its occurrence in the central nervous system (usually as a cerebral AVM ), but can appear anywhere in the body.
Lymphatic malformations are benign slow-flow type of vascular malformation of the lymphatic system characterized by lymphatic vessels which do not connect to the normal lymphatic circulation. The term lymphangioma is outdated and newer research reference the term lymphatic malformation .
Some patients with CLOVES have combined lesions (which are fast flow) and some have aggressive vascular malformation known as arteriovenous malformations (AVM). The effect of a vascular malformation varies per patient based on the type, size, and location of the malformation, and symptoms can vary.
A vascular anomaly can be either a vascular tumor or a birthmark, or a vascular malformation. [13] In a tumor such as infantile hemangioma the mass is soft, and easily compressed, and their coloring is due to the dilated anomalous involved veins. [14] They are most commonly found in the head and neck.
In medicine (gastroenterology), angiodysplasia is a small vascular malformation of the gut. It is a common cause of otherwise unexplained gastrointestinal bleeding and anemia. Lesions are often multiple, and frequently involve the cecum or ascending colon, although they can occur at other places.
As a result of this blockage, blood flow in the vessel stops—a condition called thromboembolism. [ 1 ] Thromboembolism is a condition in which a blood clot ( thrombus ) breaks off from its original site and travels through the bloodstream (as an embolus ) to obstruct a blood vessel, causing tissue ischemia and organ damage.
