Vascular Anomalies Clinic

About us

The Vascular Anomalies Clinic at SickKids sees children of all ages with vascular malformations. The clinic also sees patients with selected vascular tumours, such as hemangiomas that require surgical or radiological treatment.  Most children with vascular tumours are cared for by the Vascular Tumour Service Clinic.

To be seen at the Vascular Anomalies Clinic you will need a referral from your family physician, paediatrician or a medical specialist. 

This clinic sees patients from birth up to 18 years of age. Patients before birth with vascular anomalies are referred to the Vascular Anomalies Clinic from the fetal medicine specialists at Mount Sinai Hospital in Toronto. For patients over 18, there are specialist adult clinics within the University Health Network (see below).

Clinic/registration location

The Vascular Anomalies Clinic is part of the Plastic Surgery Clinic, located on the Main Floor, near the Black Wing elevators. From the University Avenue entrance, walk in, turn left and you will see Shoppers Drug Mart. Turn right past the Black Wing elevators and turn down the first hallway to your left. Registration for our clinic is in room M465.

When visiting SickKids an identification (ID) band will be placed on your child and must be worn on their arm or ankle at all times. To ensure your child is receiving the right care during their stay, the care team will use the ID band to check their name, date of birth and medical record number. If your child is sleeping, we’ll make sure to scan the ID band quickly and quietly so that we don’t disturb your child.  

The ID band is made of soft, latex-free material. There are two colours of ID bands: a black ID band indicates that your child has an allergy and a white ID band indicates there is no allergy. The allergy is not printed on the ID band, the care team will review the allergy in our electronic health record.

If your child’s ID band has fallen off or the information is incorrect, be sure to tell your care team. If they are not wearing an ID band or if they have the wrong one, it can lead to errors or delays that can result in the wrong care for your child.

Staff will always look at or scan the ID band before providing care to your child. This may involve

  • Asking parents or patients for two patient identifiers, such as the patient's full name and date of birth;
  • Scanning a barcode on the ID band to confirm the patient’s identity; or
  • Looking at the information on the ID band.

If you or your child are sick before your appointment

Call the clinic if you or your child have had a cold, cough, diarrhea, fever or rash within two days of your appointment, or have been sick with or exposed to chicken pox in the last three weeks. Your appointment may need to be rescheduled. 

Tell the clerk, nurse or doctor if your child has been in a hospital outside of Canada within the last 12 months. 

If you cannot come to your child’s appointment, it is important that you call the clinic as soon as possible to cancel and reschedule.

Be on time

Please arrive at least 30 minutes prior to your scheduled appointment and sign in at the registration desk in room M465.

If you are late, you may have to wait for other patients to be seen first. Allow lots of time to get to the hospital. It can take some time to get used to finding your way around and it is important to be on time for your child’s appointment. Staff will try to see your child as close to your appointment time as possible. Please understand that some patients being seen ahead of you may need more time than expected, and this can cause delay for others.

What to expect during your visit

During your first visit to the Vascular Anomalies Clinic your family will consult with one of our physicians to discuss your diagnosis and possible treatment options if necessary. Procedures and most scans will not be performed at the initial visit. You will also meet the Vascular Anomalies Clinic nurse.

As SickKids is a teaching hospital, your child may be examined by either a resident or fellow before seeing the staff physician.

With family-centered care as an essential component of our multi-professional team approach, your visit at the Vascular Anomalies Clinic may also involve our team of plastic surgeons, the haematologist, physiotherapists and occupational therapists. A social worker can be consulted on an individual basis.

To make your experience at SickKids a positive one, a Child Life Specialist may also be involved in your visit to provide therapeutic play programs designed to reduce stress, help patients cope with hospitalization, and prepare children for medical and surgical procedures.

Care of patients above 18 years of age

Patients who are over 18 years of age who have a vascular malformation are referred to dedicated Vascular Malformations Clinics at Toronto General Hospital or Toronto Western Hospital. These multi-professional clinics provide care for adult patients who are either transitioning from care at SickKids or seeing new referrals. The clinic at Toronto General Hospital is the only dedicated clinic for adults with peripheral vascular malformations in Canada.
