Fast-flow vascular malformations consist of arterial malformations, arteriovenous fistulae and arteriovenous malformations. Slow-flow vascular malformations include venous malformations, microcystic and macrocytic lymphatic malformations and capillary malformation. In this classification system, DCMO would fall under the slow-flow vascular ...
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 ...
Patients with CLOVES have different venous, capillary, and lymphatic channels - typically capillary, venous and lymphatic malformations are known as "slow flow" lesions. 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 ...
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 The term lymphangioma is outdated and newer research reference the term lymphatic malformation .
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.
Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. Magnetic resonance angiography is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions, aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities.
Cavernous hemangioma, also called cavernous angioma, venous malformation, or cavernoma, [1] [2] is a type of venous malformation due to endothelial dysmorphogenesis from a lesion which is present at birth. A cavernoma in the brain is called a cerebral cavernous malformation or CCM.
Fluid attenuated inversion recovery (FLAIR) vascular hyperintensity (FVH) is a radiographic marker seen on brain imaging in acute ischaemic stroke. FVH can be used as a proxy for slow leptomeningeal collateral blood flow, and may help reveal which areas of brain tissue are potentially salvageable. [12]
