Patient remains stroke-free for 15 years thanks to Beverly Aagaard Kienitz

Beverly Aagaard Kienitz, MD.

In 2009, Beverly Aagaard Kienitz, MD and Bermans Iskandar, MD developed the wide arterial sparing encephalo-duro-synangiosis (WASEDS) procedure, which has kept their very first patient, Danielle, stroke-free for 15 years.  

Dr. Aagaard Kienitz and Dr. Iskander developed the procedure as a treatment for Moyamoya disease after existing treatment did not work to stop Danielle’s strokes. Moyamoya disease is characterized by a narrowing or blocking of arteries at the base of the brain, which prevents blood flow.  

The WASEDS procedure began with a highly detailed map of the patient’s brain, created by Dr. Aagaard Kienitz’s angiographic images. Once the map was complete, Dr. Iskander performed the surgery, creating a series of incisions in Danielle’s brain to encourage blood vessel growth. 

The results of the surgery were everything that Danielle and her family had hoped for – her strokes stopped. Since the first surgery, Dr. Aagaard Kienitz and Dr. Iskander have performed 14 WASEDS procedures, all with the same results.
