"Cutting Edge, 21st Century Medicine"

Who We Are

The Interventional & Vascular Institute of Northern Michigan is owned by and operates under the direction of UP Superior Vascular Interventional Specialists Dr. Christopher Mehall and Dr. Michael Ouimette. The practice’s main office is located at UP Health Systems-Marquette in Marquette, MI; another clinic operates at Doctor’s Park in Escanaba, Michigan. The interventional radiologists use cutting-edge technology to diagnose and treat patients using minimally-invasive procedures.


What We Offer

Interventional Radiology is one of the fastest growing areas of medicine and is one of the most recently recognized medical specialties by the American Board of Medical specialists and the American Medical Association. Interventional radiologists specialize in minimally invasive, targeted treatments, performed under the guidance of medical imaging. They utilize their expertise in reading medical imaging studies, such as x-ray, CAT scan, MRI and ultrasound, to guide very small instruments such as catheters through the skin and blood vessels, often eliminating the need for open surgery.

Conditions treated and treatments performed by Interventional Radiologists include the following (list is not all-inclusive):
-Abdominal aortic aneurysms
-Angiography
-Angioplasty and stent placement
-Cancer treatments
-Vascular Disease
-Pelvic Congestion Syndrome (PCS)
-Uterine Fibroids

The advantages of Interventional Radiology?
– Most procedures are performed on an outpatient basis or will require only a very short hospital stay.
– Most procedures are done with mild sedation. General anesthetic is usually not required.
– Complications, pain, and recovery time are often greatly reduced as compared with traditional
treatments.


Vascular Symptoms

Abdominal Aortic Aneurism
Carotid Artery Disease and Stroke

Abdominal Aortic Aneurism: Your aorta is the main vessel that pumps blood to the rest of your body. If the walls of your aorta are weakened there is a chance for the blood to be pumped against the walls and create them to bulge, similar to a balloon, causing an Abdominal Aortic Aneurism or AAA. It is important to look out for symptoms of an AAA because if the aneurism becomes too big and ruptures, your chance of survival is low. Symptoms of AAA to look out for include:

  • Abdominal pain that may be consistent or come and go
  • The feeling of a second heartbeat in your stomach
  • Lower back pain radiating to your groin/legs/buttocks

You may be more at risk for an AAA if you have family history, are a smoker, or have high blood pressure.

Carotid Artery Disease and Stroke: Carotid Artery Disease occurs when the cholesterol (plaque) builds up in your arteries. This build up will narrow and harden your artery, sometimes blocking the artery completely. These blockages will slow down the blood flow to your brain and can become a serious risk, especially a high risk of a stroke. Because there are real no signs or symptoms of this disease, you need to watch out for the following risk factors:

  • Smoking
  • High blood pressure
  • High cholesterol
  • Diabetes
  • Obesity
  • Sedentary lifestyle
  • Family history
