Using Ultrasound for Treatment of Brain Hemorrhage

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.

SNI Communication Tools

SNI is leveraging communication tools that deliver information to patients, referring physicians and the public as a crucial part of providing care at the advancing edge of neu­rological knowledge. The goals of these tools are two-fold. One goal is to update established patients and their doctors regarding the latest developments in our programs and centers. The other is to lower the barrier for patients and physicians who are facing a new neuro­logical problem to discover tertiary subspe­cialty care.

A new SNI communication tool

Dan Rizzuto, Ph.D., director of SNI research, and John Henson, M.D., recently launched the SNI blog to complement other commu­nication efforts and to provide a communication outlet for the staff of SNI. The SNI blog offers brief notes about advances in neurological care provided in SNI’s centers, as well as news items about the institute that are of interest to our patients and referring physicians.

Blog content is more dynamic than Web content. Search engines are able to detect targeted key words within each entry, which helps direct highly relevant Web traffic to the blog. This aids in the dissemination of infor­mation to patients and physicians. Viewers also can subscribe to an e-mail notification system that will alert them to newly posted material.

Detection of Cerebral Microemboli by Transcranial Doppler

FROM BRAINWAVES: 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 seen in arteries distal to coiled aneurysms.

There is strong evidence that MES detection predicts future ipsilateral stroke risk in patients with symptomatic carotid stenosis (Markus HS, et al.; King A, et al.). A recent study of patients with asymptomatic carotid stenosis demonstrated that MES predicted subsequent ipsilateral stroke and TIA, and also ipsilateral stroke alone, and that it is helpful in selecting patients who will benefit from carotid endarterectomy.

Clinical Neurophysiology Lab Receives Accreditation

Congratulations are in order for the Clinical Neurophysiology Laboratory for attaining Accreditation by the EEG Laboratory Accreditation board of ABRET. We are the first and only Lab to receive Accreditation in Washington State and one of only 10 labs west of the Mississippi. Accreditation means the Lab has met strict standards and is recognized as a place where patients and physicians can have confidence they are receiving quality diagnostics. Thanks for all the great work and CONGRATULATIONS to everyone on the team who made this possible!
