What are vein abnormalities?

Venous malformations (VMs) are a type of type of vascular malformation that results from veins that have developed abnormally, which stretch or enlarge over time. VMs can be extremely painful and sensitive. A VM usually looks like a bluish discoloration. It can be a single lesion or it may be one of many.

What is vascular anomaly?

Vascular anomalies are abnormalities or disorders of the vascular system, either in veins or arteries. Vascular anomalies are classified as either a vascular tumor or a vascular malformation. Blood is pumped through the body in tube-like structures called blood vessels. These vessels form a network.

Is venous malformation serious?

The malformation may increase the risk of developing blood clots in the deep veins (deep vein thrombosis, DVT), which is a serious medical condition. If these deep blood clots travel to the blood vessels of the lungs (pulmonary emboli, PE), this can be life-threatening.

Why do I suddenly have a varicose vein?

Varicose veins are usually caused by weak vein walls and valves. Inside your veins are tiny one-way valves that open to let the blood through, and then close to prevent it flowing backwards. Sometimes the walls of the veins become stretched and lose their elasticity, causing the valves to weaken.

What is the most common venous malformation?

Venous malformation (VM) is the most common type of congenital vascular malformation (CVM). They are present at birth and are often symptomatic, causing morbidity and pain. VMs can be challenging to diagnose and are often confused with hemangioma in terminology as well as with imaging.

What is Parkes Weber Syndrome?

What is Parkes Weber syndrome (PWS)? PWS is an exceptionally rare congenital (present at birth) vascular anomaly that results in a child having a large number of abnormal blood vessels. It’s similar to the more common Klippel-Trenaunay syndrome (KTS) and is treated in much the same way.

How is venous malformation treated?

Sclerotherapy is the primary form of nonsurgical intervention for venous malformations. Larger lesions usually are treated with 95% ethanol, while cutaneous and smaller lesions are treated with sodium tetradecyl sulfate (1%). Sclerotherapy is often performed by an interventional radiologist under general anesthesia.

How is venous anomaly treated?

Generally, developmental venous anomalies (DVAs) do not require treatment. These veins do a necessary job of getting blood in and out of the brain, so they do not need to be surgically removed or closed. Because they are normal and not dangerous, long-term imaging is generally not necessary.

What causes Weber Syndrome?

Weber’s syndrome is a neurological condition caused by an injury to the midbrain, the uppermost section of the brain stem. It’s usually caused by a stroke (infarction), but in rare cases, Weber’s syndrome can also be caused by a brain tumor, a traumatic injury, or infection.

Is Parkes Weber Syndrome painful?

pain — often severe — in the affected limb. heart problems from increased blood flow through an arteriovenous malformation.
