Health Information For Parents
A venous malformation (VM) is a place in the body where veins haven’t grown the right way. Veins in a VM tend to be larger and more tangled than normal veins. A VM in the skin usually looks like a maroon, blue, or purple spot.
Kids who have VMs are born with them. A VM might not be visible until later when it has gotten bigger or its veins have stretched. A VM grows as a child grows and may also grow in response to injury or partial removal.
Kids with VMs may have these symptoms:
Venous malformations are the most common of all of the vascular malformations (also called vascular anomalies). These are problems that happen when blood vessels (capillaries, arteries, veins, or lymphatic vessels) don’t develop as they should.
Most VMs have no clear cause, but some are due to genetic problems and may run in families.
Some rare genetic conditions that include VMs are:
A VM is usually diagnosed based on a child’s health history, pictures and imaging of the VM, and an examination.
To learn more about how the VM is attached to other blood vessels and to see if internal organs are affected, the doctor may order these imaging tests:
VMs can be very difficult to treat and often grow back after removal. So a VM is usually treated only if it:
Evaluation by a vascular anomaly specialist is recommended for VMs in sensitive areas such as the face, neck, hands, or feet or when VMs affect internal organs.
VM treatment may include doctors from several different specialties and include:
VMs tend to get bigger as a child grows. Regular follow-up with your doctor is important.
Research is ongoing for both the treatment of VMs and the prevention of regrowth after treatment. New medicines and genetic research for VMs and other vascular problems are advancing and new treatments might be available in the next few years.
An arteriovenous malformation (AVM) is an abnormal connection between an artery and a vein. Large AVMs or multiple AVMs usually needs medical treatment.
Birthmarks that babies are born with, or develop soon after birth, are mostly harmless and many even go away on their own, but sometimes they’re associated with certain health problems.
The heart and circulatory system are our body’s lifeline, delivering blood to the body’s tissues. Brush up on your ticker with this body basics article.
The heart and circulatory system (also called the cardiovascular system) make up the network that delivers blood to the body’s tissues.
For most kids, these birthmarks are no big deal â they’re just part of who they are. Read about port-wine stains, how to care for them, and, if necessary, what treatments are available.
When Anna was born, she developed red spots that her parents learned were hemangiomas, benign birthmarks that she eventually outgrew. Her mother tells her story.
This is a big word for a type of birthmark.
Birthmarks, also known as hemangiomas, get their name for one reason: They are marks on the skin of a lot of newborn babies! Find out more about birthmarks in this article for kids.
CLOVES syndrome is a very rare genetic disorder that causes vascular, skin, spinal, and bone or joint abnormalities.
A hemangioma is a growth of tangled blood vessels. Most hemangiomas grow larger for several months, then shrink slowly. Some will require treatment.
