About Our Clinic

Vascular anomalies, also called vascular malformations, are birthmarks or growths caused by abnormally developed blood vessels. Many vascular anomalies are present at birth; however, some do not appear until later in life. Vascular anomalies can cause various symptoms, including:

  • Pain
  • Swelling
  • Bleeding
  • Infection
  • Deformity

Due to their rarity, vascular anomalies are often considered an “orphan disease,” in that patients with vascular anomalies can experience difficulty in finding a “medical home” for the treatment of their condition. Also, many vascular anomalies centers are based out of children’s hospitals but only serve a pediatric population, which leads to difficulties in the transition from pediatric care to adult medicine. Our clinic addresses these issues by providing highly specialized vascular anomaly care for both children and adult patients, offering seamless transitional care between the two groups.

We have the experience and expertise to ensure accurate diagnosis of all types of vascular anomalies, from simple birthmarks to the most complex malformations. Once a disorder has been diagnosed and assessed, our team works together to develop and implement a coordinated care plan to address your or your child’s specific needs. Our clinic brings together a depth of knowledge from multiple UH Rainbow sub-specialties and services to offer the best possible care, all provided in a child-friendly atmosphere at a single convenient location.

Vascular Anomalies We Treat

The vascular anomalies we treat include the following:

Note: Infantile hemangioma, which is a common blood vessel birthmark seen in infants, is treated by the pediatric dermatology team at UH Rainbow Babies & Children’s Hospital. To refer a patient for an infantile hemangioma, please call 216-286-7285.

We offer access to vascular anomaly-related research studies, including clinical trials.

A Multidisciplinary Approach to Treatment

Our mission is to provide a multidisciplinary approach to the evaluation and management of both pediatric and adult patients with vascular tumors and vascular malformations. In leveraging our multiple specialties and complimentary expertise, our team provides the highest level of care for the full spectrum of simple and complex vascular anomalies.

UH Rainbow’s multidisciplinary VAC is located at the Zagara Pediatric Specialty Clinic at our main campus in Cleveland, Ohio. At this convenient location, patients have access to pediatric dermatologists, plastic surgeons, ophthalmologists, hematologist/oncologists, otolaryngologists (ENT), geneticists and radiologists who work together to provide the best vascular anomaly treatment available to patients of all ages.

The advantages to a multidisciplinary approach are that patients are able to obtain comprehensive consultation and are offered a coordinated care plan in one visit, as opposed to meeting with different specialists individually. This means that treatment plans can be individualized based on what is in the best interest of the patients.


The Vascular Anomalies Clinic is open the first Wednesday of every month: 12:30 p.m. – 4:00 p.m.

Our virtual clinic is held the third Wednesday of every month: 8:00 a.m. – 10:00 a.m.
