Overview
Rare vascular malformation of major vessels is an uncommon condition where the large blood vessels in the body — such as the aorta, vena cava, pulmonary arteries, or other major arteries and veins — develop abnormally. These malformations can be present from birth or may become apparent later in life. The abnormal blood vessels may be too wide, too narrow, twisted, or have unusual connections between arteries and veins. This can affect how blood flows through the body and may lead to serious complications depending on which vessels are involved and how severely they are affected. Symptoms vary widely depending on the location and type of malformation. Some people may have no symptoms for years, while others may experience pain, swelling, skin changes, or problems with blood flow to organs. In severe cases, these malformations can cause bleeding, blood clots, or strain on the heart. Some malformations may grow or change over time, especially during periods of growth or hormonal changes. Treatment depends on the specific type and location of the malformation. Options may include monitoring with regular imaging, minimally invasive procedures such as embolization (blocking abnormal vessels), stenting, or open surgery. A multidisciplinary team of specialists typically manages care. There is no single cure that works for all types, and treatment is often focused on managing symptoms and preventing complications. Research into the genetic causes and targeted therapies is ongoing but still in early stages for many subtypes.
