As of 12/31/2022, Dr. (Tony) Otoadese is retiring, and Northern Iowa Cardiovascular and Thoracic Surgery Clinic is closing. Allyson Landphair ARNP and staff have joined UnityPoint Cardiovascular and will continue to provide Vascular services to current and new patients at their new location 2413 West Ridgeway Avenue, Waterloo. She may be reached at 319-233-6211 or 319-236-1911.

If you already have an appointment scheduled for an ultrasound or to see Allyson you do not need to call to make a new appointment, but a representative may be calling you to adjust your appointment time. She will have access to your current medical records for continued care.

We have contracted with medical records custodian, Shoreline Records Management, Inc. Authorized requestors will request their records from Shoreline by accessing their website and selecting the “Records Request” tab on the home page. If you are a current patient, you may access your records by linking to the “Patient Portal” on the upper right corner of this page.

Patients must fill out a complete HIPAA authorization form to submit a request. When they receive the HIPAA form back, they will notify the requestor of the processing fee and send a credit card authorization form. They charge $.75 per page not to exceed $100.00. Once payment is received, they will send a secure link via email chart, or patients may request a CD mailed to their address, for an additional $10.00 fee.

Sincerely, Dr. Otoadese and Staff

Our Complete List Of Ultrasounds

  • Simple, Noninvasive Screenings
  • Extremity Dopplers
  • Carotid Dopplers
  • Venous Disease Screenings
  • Ultrasound Evaluations for Abdominal Aortic Aneurysm (AAA)
  • General Ultrasound Studies

Procedures and Surgeries:

  • Arteries: We are able to offer multiple different surgical options for vascular needs. Often times we are able to perform repair of blockages and even aneurysms with a simple catheter approach. This endovascular approach allows for quicker healing times which will allow the return of normal activities much sooner than the open options. However, there are times in which an open surgical repair is the best treatment for the longevity of the vessel.

  • Veins: We utilize a radiofrequency catheter for vein closure. This allows for a lower heat to be utilized while closing the veins. Sclerotherapy is an office based procedure that can be utilized to close off poorly working veins.

  • Lungs: VATS (Video Assisted Thoracoscopy) can be utilized by making 3 very small incisions and using a camera to assist in the procedure. An open repair or Thoracotomy may be used for larger more extensive surgeries. Mediastinoscopy can be done with a small incision for the purpose of obtaining a biopsy for diagnosis.


We provide both general and vascular ultrasounds for your diagnostic needs. These studies can take as little as fifteen minutes or up to an hour depending on the complexity of the study.


Lungs provide oxygen to the blood. If you find yourself with a lung problem that requires a surgical treatment we can provide anything from a biopsy for diagnosis to resection for treatment and possible cure.


Arteries carry oxygenated blood to the organs and tissues in your body from your heart. Veins return blood back from the organs and tissues to your heart to be replenished with oxygen. Problems with blood flowing away from and back to your heart can impede your health and ability to perform your normal daily activities.

Carotid Doppler

The carotid arteries are major blood vessels which provide blood flow to the brain. If one or both of these arteries have blockage it could increase your chance for a stroke. We are able to test for and treat blockages of the carotid arteries.

Treatment of vascular disease may include multiple steps. Often times, patients have not only venous but arterial disease. It is our job to narrow down the problem and focus on how to make your legs look and feel their best. Varicose Veins for instance are not always simply a cosmetic issue. They often cause pain and swelling which can affect your daily life. Additionally, Arterial blockages in your legs can also affect your ability to walk and function throughout the day.
