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 The term lymphangioma is outdated and newer research reference the term lymphatic malformation .
Sclerotherapy (the word reflects the Greek skleros, meaning hard) [1] is a procedure used to treat blood vessel malformations (vascular malformations) and also malformations of the lymphatic system. A medication is injected into the vessels, which makes them shrink. It is used for children and young adults with vascular or lymphatic malformations.
Venous malformations are the type of vascular malformation that involves the veins. They can often extend deeper from their surface appearance, reaching underlying muscle or bone. [12] In the neck they may extend into the lining of the mouth cavity or into the salivary glands. [11] They are the most common of the vascular malformations. [13]
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.
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 ...

Chronic venous ulcers are painful and debilitating. Even with treatment, recurrences are common if venous hypertension persists. Nearly 60% develop phlebitis which often progresses to deep vein thrombosis in more than 50% of patients. The venous insufficiency can also lead to severe hemorrhage.
