Vascular malformations are abnormal formations of veins, arteries, capillaries, or lymphatic vessels that develop before birth and can cause a range of health complications. These conditions vary in severity, with some remaining asymptomatic while others lead to pain, swelling, disfigurement, and serious medical risks such as bleeding, clotting, and organ dysfunction.
At Vascular Surgery Associates, our top vascular specialists in Los Angeles and Santa Monica provide expert diagnosis and cutting-edge treatment options to manage and treat vascular malformations effectively. Using advanced imaging and minimally invasive procedures, we help patients restore proper blood flow and improve quality of life.
What Are Vascular Malformations?
Vascular malformations are congenital abnormalities of the circulatory system, meaning they are present at birth and grow over time rather than appearing suddenly. Unlike vascular tumors (such as hemangiomas), vascular malformations do not shrink on their own and often require medical intervention.
These malformations can affect any part of the body, including the skin, muscles, bones, and internal organs. According to the National Organization for Rare Disorders (NORD), vascular malformations occur in approximately 1 in 5,000 people.
Types of Vascular Malformations
Vascular malformations are classified based on the type of blood vessels involved and their impact on circulation.
Venous Malformations
Dilated, abnormally formed veins that cause swelling, pain, and clotting risks
Arteriovenous Malformations (AVMs)
Abnormal connections between arteries and veins, leading to high blood flow, tissue damage, and potential rupture
Capillary Malformations
Also known as port-wine stains, these malformations cause reddish discoloration of the skin due to abnormal capillaries
Lymphatic Malformations
Affect the lymphatic system, leading to fluid buildup, swelling, and infection risks
Mixed Malformations
A combination of multiple vessel abnormalities, which can complicate diagnosis and treatment
Each type of malformation requires specialized care to prevent complications and improve long-term health outcomes.
Symptoms of Vascular Malformations
The symptoms of vascular malformations depend on their location, size, and type but commonly include:
- Visible skin discoloration (red, blue, or purple patches)
- Swelling and pain in the affected area
- Pulsating mass or abnormal blood flow felt under the skin
- Increased warmth over the malformation due to high blood flow
- Frequent bleeding or ulceration in the affected region
- Neurological symptoms (headaches, seizures, or weakness) in cases involving the brain
Without proper treatment, vascular malformations can worsen over time, leading to functional impairment, chronic pain, and life-threatening complications.
How Are Vascular Malformations Diagnosed?
At Vascular Surgery Associates, we use advanced diagnostic imaging to assess the severity and complexity of vascular malformations.
Doppler Ultrasound
Evaluates blood flow abnormalities in the affected vessels
MRI & MR Angiography (MRA)
Provides detailed images of vascular structures and surrounding tissues
CT Angiography (CTA)
Helps detect arteriovenous connections and high-flow lesions
Catheter-Based Angiography
Offers real-time visualization of vascular malformations, guiding treatment decisions
Early diagnosis is crucial to prevent complications and determine the best treatment plan.
Treatment Options for Vascular Malformations
The best treatment approach depends on the type, size, and location of the vascular malformation. Our Los Angeles and Santa Monica vascular specialists offer both minimally invasive and surgical interventions to manage symptoms and restore proper circulation.
Minimally Invasive Treatments
Sclerotherapy
A specialized injectable solution causes the abnormal vessels to collapse and shrink over time
Embolization Therapy
A catheter-based procedure blocks off high-flow connections in arteriovenous malformations (AVMs)
Laser Therapy
Used for capillary malformations (port-wine stains) to improve cosmetic appearance and reduce discoloration
Surgical Treatments
Surgical Excision
For large or symptomatic malformations, removing the affected tissue may be necessary
Bypass Surgery
In severe cases, rerouting blood flow can help preserve function and prevent complications
Lymphatic Drainage
Procedures Used for lymphatic malformations to reduce swelling and prevent infections
Each patient receives a personalized treatment plan, ensuring the most effective and least invasive approach whenever possible.
Frequently Asked Questions About Vascular Malformations
While some vascular malformations remain harmless, others–especially arteriovenous malformations (AVMs)–can lead to severe complications such as bleeding, clotting, and tissue damage.
Unlike vascular tumors, vascular malformations do not shrink or disappear without treatment. In many cases, they enlarge over time and require medical intervention.
If you experience pain, swelling, frequent bleeding, or impaired function, seeking evaluation from a vascular specialist is recommended.
The best treatment depends on the type of malformation, but options include sclerotherapy, embolization, laser therapy, and surgical removal.
Vascular malformations are congenital (present at birth) and cannot be prevented, but early diagnosis and treatment can prevent complications and improve quality of life.
