complex-combined types. slow-flow vascular malformations capillary malformation capillary malformation (also known as port-wine stains): capillary malformations are flat, reddish lesions that typically affect the skin, mostly around the head and the neck, and which darken with age, in contrast to birthmarks such as salmon patch, nevus simplex or vascular stain, which lighten or disappear within the first few years of life. capillary malformations constitute 11% of the vascular malformations. syndromes associated with capillary malformations are: sturge–weber syndrome and klippel–trénaunay syndrome. capillary malformations can be treated with ipl-(intensed-pulsed-light)-therapy or surgical resection. venous malformation is a bluish lesion compressible on palpation; the masses enlarge with physical activity or if in a dependent position. the bluish lesion is caused by dilated venous vessels. venous malformations can be painful in the morning due to stasis and microthrombi within the veins. venous malformations usually occur in the head and neck. venous malformations are the most common vascular anomaly, making up 40% of all vascular malformations. they can be treated with sclerotherapy and surgical resection. lymphatic malformation lymphatic malformation is a benign growth of the lymphatic system. they result from a blockage or defect of the lymphatic vessels as they are forming. 28% of all vascular malformations are lymphatic malformations. lymphatic malformations can be treated with sclerotherapy and surgical resection. fast flow vascular malformations all fast-flow malformations are malformations involving arteries. they constitute about 14% of all vascular malformations. arterial malformation arteriovenous fistula (avf) : a lesion with a direct communication via fistulae between an artery and a vein. arteriovenous malformation : a lesion with a direct connection between an artery and a vein, without an intervening capillary bed, but with an interposed nidus of dysplastic vascular channels in between. combined-complex vascular malformations a combination of various vascular malformations. they are 'complex' because they involve a combination of two different types of vessels. cvm: capillary venous malformation clm: capillary lymphatic malformation lvm: lymphatic venous malformation clvm: capillary lymphatic venous malformation. clvm is associated with klippel–trénaunay syndrome avm-lm: arteriovenous malformation- lymphatic malformation cm-avm: capillary malformation- arteriovenous malformation terminology correct termincorrect terminology commonly used to describe vascular anomalies hemangiomastrawberry hemangioma capillary hemangioma cavernous hemangioma kaposiform hemangioendothelioma(capillary) hemangioma pyogenic granulomahemangioma capillary malformationport-wine stain capillary hemangioma lymphatic malformationlymphangioma cystic hygroma venous malformationcavernous hemangioma arteriovenous malformationarteriovenous hemangioma
