Vascular anomalies are conditions that affect how your child’s arteries, veins, lymphatic vessels, or capillaries develop. Some are first noticed on a prenatal ultrasound, while others appear in infancy or early childhood. These conditions can range from simple birthmarks to complex malformations that affect blood flow or organ function.

At University of Iowa Health Care Stead Family Children’s Hospital, you have access to pediatric specialists who understand how these anomalies behave, grow, and change over time. Our fetal cardiology, pediatric cardiology, imaging, and surgical teams work together to give you a precise diagnosis and a clear plan for treatment.

What sets us apart

At UI Health Care, you have access to pediatric specialists who understand how these anomalies behave, grow, and change over time. Our fetal cardiology, pediatric cardiology, imaging, and surgical teams work together to give you a precise diagnosis and a clear plan for treatment.

Symptoms of vascular anomalies

Vascular anomalies can look and behave differently depending on the vessel involved. You should contact your care team if you notice any of the following symptoms:

Skin discoloration or visible markings

Soft or firm masses under the skin

Swelling in a limb or part of the body

Rapidly growing lesions in infancy

Breathing or feeding concerns

How vascular anomalies are diagnosed

Your child’s evaluation may begin even before birth through our fetal cardiology program, which uses advanced imaging to assess heart structure and blood flow. After birth, if symptoms appear, your child’s care team will review their health history, symptoms, and perform a thorough physical examination. They may also order diagnostic tests such as:

Our specialists will explain every step in clear, supportive language, so you understand what the findings mean and what to expect next.

Treatment for vascular anomalies

Treatment depends on the type and severity of the anomaly. Many mild conditions only require monitoring, while others benefit from medication, procedures, or surgery. We tailor every plan to your child’s needs.

Observation and monitoring

Some vascular anomalies simply need time and a careful watch. We track growth and symptoms and guide you on what to look for at home.

Medication

Certain anomalies — such as infantile hemangiomas — respond well to medications like beta-blockers, which can slow or shrink the growth

Laser therapy

Laser treatment can improve the appearance or symptoms of skin-based vascular anomalies such as port-wine stains.

Interventional radiology procedures

Our specialists use minimally invasive options such as sclerotherapy or embolization to reduce or block abnormal blood flow.

Surgery

Surgery may be recommended for anomalies that cause symptoms, affect organ function, or don’t respond to other therapies. Our surgeons work closely with cardiology and imaging to plan the safest approach.

Coordinated, multidisciplinary care

Because vascular anomalies can affect breathing, feeding, circulation, or a child’s overall development, we bring together the right specialists at every stage of care. Our multidisciplinary team may include experts from otolaryngology, dermatology, oncology, cardiology, and pediatric surgery, ensuring your child receives comprehensive, well‑coordinated evaluation and treatment.

Support services for vascular anomalies

We know your family needs support beyond medical care. That’s why you have access to child life services, social work, nutrition guidance, and genetic counseling when appropriate. We’ll also help coordinate follow-up appointments and connect you with additional specialists as needed.

A collaborative approach to care

Your child’s care begins with a thorough evaluation by a pediatric cardiology, fetal cardiology, or vascular anomalies specialist. We review imaging together, explain the diagnosis in clear terms, and outline next steps. You’ll have a coordinated team guiding you from diagnosis to treatment and follow-up, with specialists collaborating behind the scenes to provide your child with the safest, most comprehensive care.

Common questions about vascular anomalies

Are vascular anomalies preventable?

Most pediatric vascular anomalies are congenital and not caused by anything a parent does during pregnancy. They often occur due to genetic changes that happen spontaneously.

Do vascular anomalies grow over time?

Some do. Early evaluation helps us predict how an anomaly may behave and whether treatment is recommended now or later.
