General Information

For more information see: seattleneurosciences.com David W. Newell, M.D. is a board certified neurosurgeon specializing in cerebrovascular neurosurgery, brain aneurysms, spine surgery, stroke and arteriovenous malformations. Dr. Newell previously held the position of Professor of Neurological Surgery at the University of Washington School of Medicine. In addition to directing the University’s Cerebrovascular Lab, he was Chief of Neurosurgery at Harborview Medical Center, where he specialized in the care of brain injury and spinal cord injury. Dr Newell was one of the original authors of “Guidelines for the Management of Traumatic Brain Injury “by the Brain Trauma Foundation, which were established as the first evidence based guidelines in Neurosurgery, to be endorsed by multiple professional societies. Dr. Newell’s research interests have included mechanisms of regulation of cerebral blood flow and the use of ultrasound in the diagnosis and treatment of brain disorders. He was the first neurosurgeon in the United States to perform research and publish results on the use of Transcranial Doppler Ultrasound in neurosurgical patients and helped introduce this technology in the United States as part of the care and treatment of patients with cerebral aneurysms. Dr. Newell has won numerous honors, awards and distinctions including: Best Doctors in America®, Super Doctors, Seattle Magazine, Seattle Metropolitan Magazine, Washington Magazine, Consumer’s Guide to Top Doctors, Health Network Service Excellence Award, Castle Connolly Medical Ltd., and Av vo, one of the nation's leading companies involved in quality metrics in health care. He was the recipient of 1989 National Stroke Association Fellowship Award and the William P. Van Wagenen Fellowship from the American Association of Neurological Surgeons. He is the principal investigator for many clinical trials, holds multiple NIH grants and is an author of numerous medical journal publications and books, including the No. 1 medical textbook on brain aneurysms titled "Management of Cerebral Aneurysms" (Elsevier Inc., 2004). Currently he serves on the Medical Advisory Board of Directors for The Brain Aneurysm Foundation.

Treating Arteriovenous Malformations to Remove the Risk of Rupture

June 28, 2013

An arteriovenous malformation (AVM) in the brain is a relatively rare condition – occurring in less that 1 percent of the population. It can, however, be neurologically morbid in young adults ages 15 to 20, who are at the greatest risk for hemorrhage and least likely to exhibit symptoms. About 2 to 4 percent of all AVMs each year hemorrhage.

An AVM’s tangled mass of blood vessels, which forms in utero, produces multiple direct connections between arteries and veins without the normal, intervening capillaries. Symptoms often are not present until later in life or until after the AVM ruptures.

A small number of congenital syndromes, such as Sturge-Weber, Rendu-Osler-Weber, ataxia telangiectasia, and Wyburn-Mason, are associated with AVMs. Once formed, extrinsic factors, such as arterial shunting, growth factors and intracranial hemorrhage, may alter the size and shape of an AVM.

The most common types of AVMs are:

Using Ultrasound for Treatment of Brain Hemorrhage

January 26, 2012

In September, I co-authored this cover article in the Journal of Neurosurgery on the results of a study using ultrasound for the treatment of brain hemorrhage. The study involved 33 patients with spontaneous intracerebral hemorrhage who were screened for inclusion in a SNI clinical study known as “SLEUTH” (Safety of Lysis with Ultrasound in the Treatment of Intracerebral and Intraventricular Hemorrhage). You can the abstract and full text of the article or see background information on the study, and watch a related video on WebMD.

Detecting cerebral microemboli with transcranial doppler

March 14, 2011

Since its introduction in 1982, transcranial doppler ultrasound (TCD) has evolved into a por­table, multimodality, noninvasive method for real-time imaging of intracranial vasculature.

The detection of cerebral microemboli is among the more remarkable capabilities of TCD. Emboli create countable signals in the ultrasound display due to the higher reflection of sound waves compared to the blood cells. Experimental mod­els have shown a high sensitivity and specificity for detection of a variety of substrates, including thrombotic, platelet and atheromatous emboli.

Microembolic signals (MES) within the in­tracranial vasculature are most frequently identi­fied in patients with large-vessel atherosclerotic disease, such as carotid stenosis. They have also been reported in intracranial arterial stenosis, ar­terial dissection, cardiac disease and atheroaortic plaque. Additionally, they have been...

Patient Ratings and Comments

The Patient Rating score is based on responses given during the CAHPS Patient Experience Survey. Responses are measured on a 10-point scale, with 10 being the best score. These scores are then translated to a 5-point scale in order to display results in a 5-star rating. Comments are also gathered from the same survey and displayed in their entirety with the exception of any language that may be considered slander, libel or contain private health information, which will be removed prior to publishing the comments.

4.5 out of 5 (62 Ratings, 9 Comments)


Dr. probably best in our region for aneurysms, and treatment was exceptional.

Excellent all the way have already told others of my experience.

Excellent or superior.

Dr. Newell and his staff are awesome! I have full confidence of his care.

The dr. was very caring I was very happy.

easy to understand dr. made me feel confident about upcoming surgery

Met all my expectations

This was a very impersoanl and cold experience. He was confused about why I was there. I was confused. He did not explain well and rushed through to get me out of there.

My doctor and the nurse practitioner were very thorough, cordial and I was satisfied with their explanation of my health issues.
