The value using Intraoperative ultrasound; Simple, Useful in many areas of the brain and body;

SUMMARY: Dr. Samuel Kaba of Ghana describes his use of intra-operative ultrasound in neurosurgery. In many countries, intra-operative CT, MR and Neuro-navigation is unaffordable. Ultrasound is inexpensive, provides realtime images, without and is not influence by brain shift. It is practical and easy to use with a short learning curve. As Dr. Kaba states, "the more you do,  the more you do". It can be useful in tumor resections, estimating the volume of tumor removed, hematoma aspiration, biopsies, shunt placement, locating metastatic lesions, EVD placement and more. It produces  live, realtime, images of lesions and can be used without neuronavigation for these reasons. Some places with Neuro-navigation also use ultrasound these reasons. He prefers ultra sound to neuro-navigation as a neuro-navigation tool.  Improvements in ultrasound technology are coming. Ultrasound uses different modes in which the depth can be measured and blood flow can be imaged. Once the data is collected, it can be analyzed in different ways. There are different probes depending on the application: measuring flow in small vessels requires a small probe, for example. Dr.  Kaba then shows its use in operations with real images in multiple different clinical applications that must be seen to appreciate the value of the instrumentation. it is useful in awake surgery. During surgery you can see the tools you use with the ultrasound. No installation necessary or modification of the operating room. It is portable and can be used by other specialties.  This is a very practical, useful presentation that has a large benefit to neurosurgeons everywhere.  The discussion following the presentation is very useful. What to tell the vendor to have the best use for neurosurgery.  Ultrasound systems can be purchased with cell phone use for low costs. An excellent practical presentation.
