Vasospasm Surveillance With Transcranial Doppler Sonography in Subarachnoid Hemorrhage.

The use of transcranial Doppler monitoring for the diagnosis of vasospasm in subarachnoid hemorrhage is backed by national guidelines. However, it remains poorly used across neurologic intensive care units in the United States. This current practice article uses 2 clinical vignettes to illustrate the simplicity and logic behind routine daily surveillance of vasospasm with transcranial Doppler s...

Grading and hemodynamic follow-up study of arteriovenous malformations with transcranial Doppler ultrasonography.

This study presents and tests the clinical validity of a hemodynamic grading system that depends on noninvasive transcranial Doppler ultrasonographic parameters. The suggested transcranial Doppler-based grading system was compared with the Spetzler-Martin anatomic grading for prognosticative validity and clinical dependability. We concluded the following: (1) The pulsatility index was shown to ...

Frequency of Opium Addiction with Ischemic Stroke Patients and Comparing Their Cerebrovascular Doppler Ultrasound Alternations to Non-Addicts

Background: Ischemic stroke is a major cause of mortality and morbidity worldwide. Various studies on the etiology of this disease are in progress. Some studies have suggested that opium abuse may is associated with increased risk of ischemic stroke. The present study aimed to analyze the frequency of opium addiction and to compare cerebrovascular ultrasound patients’ changes to non-addicts. Me...
