Why choose Arizona Doppler

AZ Doppler is an accredited mobile ultrasound laboratory with the Intersocietal Commission for the Accreditation of Vascular Labs (ICAVL). We have achieved accreditation in the following areas: Venous, Arterial, Extracranial and Visceral Doppler. To be granted accreditation with ICAVL a vascular lab must demonstrate a commitment to quality by following the highest standards and submit extensive case documents of these standards for peer review before accreditation can be achieved and granted.

Zamboni Doppler Training and Protocol at Arizona Doppler

Eric Feigenbutz, BS, RVT and President of Arizona Doppler Specialists has taken special interest in providing the most accurate and comprehensive Doppler screenings for CCSVI. Eric attended his first symposium on CCSVI at State University of New York Downstate Medical Center on July 26, 2010 to learn more about the CCSVI hypothesis, the specific protocol and to hear from specialists from around the world. He quickly realized that just reading about Dr. Zamboni’s protocol was not enough to provide accurate assessment for CCSVI, so Eric selected Buffalo Neuroimaging Analysis Center at Buffalo General Hospital in New York for training. He has trained each of our technologists to follow this specific and detailed protocol. Each technologist performing CCSVI Doppler ultrasound screenings for AZ Doppler has been trained to follow the Zamboni specific protocol.

About the CCSVI

Dr. Paolo Zamboni, an Italian doctor and former vascular surgeon, developed a new type of treatment/therapy for MS patients suffering from CCSVI called ‘The Liberation Therapy’. According to Dr. Zamboni, MS is possibly not a chronic disease of the central nervous system, but a disease of the vascular system.  Narrowed blood vessels cause unnourished blood full of toxins to back up in the brain and not drain from the central nervous system.  Some believe that this combination of events causes the symptoms of MS.  The liberation angioplasty treatment inserts a catheter with balloon into the patient’s vein, thereby opening the vessel so that the blood can drain properly.

Patients who could barely walk or perform basic functions controlled by the central nervous system are experiencing dramatic life-changing results.
