About Us

Who Are We?

Barrie Vascular Associates are a group of Vascular Surgeons that manage all aspects of the care vascular disease for the region of North Simcoe Muskoka LHIN and its surrounding communities. These surgeons work out of an office located at 60 Bell Farm Rd and out of Royal Victoria Hospital and Orillia Soldiers Memorial Hospital where they perform surgical procedures for a wide range of vascular conditions.

What is Vascular Surgery?

Vascular surgery is a surgical specialty that is dedicated to the treatment of conditions affecting blood vessels including arteries, veins and the lymphatic system. Some of the common vascular conditions treated include aortic aneurysms, stroke and mini strokes from carotid artery narrowing, poor leg circulation and varicose veins. The vascular surgeon is well trained to offer complete therapy such as patient counseling, medical treatment, minimal invasive balloon angioplasty, stenting of arteries and veins as well as reconstructive vascular surgery.

Preparation For Your Test

Depending on the test you have scheduled, there may be some advance preparation, such as fasting or avoiding certain foods or drinks. If you are unsure about your regular medications or any other pre-test instruction please call us to be sure. It is very frustrating for you and us to have you arrive for your test and find that you were to prepare in a certain way and haven't, thereby making test results inaccurate.

We suggest you wear comfortable loose-fitting clothes the day of the test. Some tests require that you change into a gown. We ask that you check in at least 15 minutes prior to your appointment time. If you arrive late for your appointment you may be asked to reschedule.

Your Appointment

Appointments are made from a referral from physician that is faxed to the office.

The doctor will be notified of the appointment and patients will be notified by the referring physician.

Please be sure to bring your Health Card for every appointment.

If you are unable to keep your scheduled appointment please call the office in advance at either of the numbers listed above.

Please note that appointments are subject to change as our doctors provide Emergency surgery and treatment to the community that may interrupt their scheduled clinic appointments

Please follow the instructions for fasting prior to Imaging tests which are listed on the Patient Instruction form above.

Your Results

Following your test, the results will be analyzed by Dr. Sandy McDonald and a report will be forwarded to the Physician that referred you to our facility. It is your Physician's responsibility to share the findings with you.

Your Physician may or may not call you to discuss the results. You may want to ask your doctor's office what their procedure is for relaying information regarding your results - i.e. "No News is Good News" or " Call the office in one week for results" or "I will call you to arrange an appointment to discuss".
