Vascular Anomalies Center | For Patients & Families

Because of their complex nature, vascular anomalies call for more than medical care. In addition to our comprehensive, interdisciplinary clinical services, the Vascular Anomalies Center also provides information and support for patients and families.

During your visit

VAC clinic

Boston Children's VAC holds weekly interdisciplinary clinics. These clinics give patients with vascular tumors or vascular malformations and their families the opportunity to see more than one specialist during the same visit.

Because more complex vascular anomalies may involve multiple body systems, the ability to have multiple specialists in the room at the same time — each bringing their area of expertise — allows physicians to have an immediate back-and-forth interchange and share their assessments with one another, as well as with patients and family members. This allows us to accurately diagnose you or your child’s condition and propose a customized treatment plan that meets the individual needs of each patient.

At the end of your clinic visit, you will leave with a recommended treatment plan, and if needed, appointments for follow-up care.

The interdisciplinary clinics are held in the Longwood location.

In addition to the interdisciplinary clinics, medical clinics are held by many of the VAC physicians in various Boston Children’s locations. The VAC coordinators and nurse practitioners will work with you to determine the best clinic to meet your needs.

Nurse practitioner clinic

There are many different types of vascular anomalies, ranging from simple infantile hemangiomas to complex combination vascular malformations such as Klippel-Trenaunay syndrome. For more complex vascular anomalies, an evaluation in the interdisciplinary VAC clinic is important. For other simple vascular anomalies, a specialized nurse practitioner can provide a timely clinical evaluation.

During the nurse practitioner clinic, a patient will meet with one of our highly experienced nurse practitioners, all of whom have specialized expertise in vascular anomalies. The nurse practitioners will:

  • perform a clinical evaluation
  • provide a diagnosis
  • discuss possible treatment

The nurse practitioners also educate patients and families about their diagnosis, help to allay fears, and empower patients and parents.

During the clinic evaluation, the VAC nurse practitioner may determine that consultation with one or more of our physician specialists is in your or your child's best interest. The nurse practitioner may be able to arrange a physician consultation on the spot, or will schedule a follow-up appointment for another time.

Depending on your child's possible diagnosis, we may perform one or more of the following during your visit:
