Zug, Switzerland –17 November 2010 - ALOKA Holding Europe AG, the innovator in ultrasound, is working with internationally renowned neurosurgeon, Dr Klaus Resch of the University of Greifswald and Klinikum, München (Germany), to promote the potential for ultrasound to be used in conjunction with, or as a replacement for, CT/MRI as a neuro-navigational tool in certain operations.

As part of this initiative, Dr Resch has this month began planning to extend his training programme for neurosurgeons across all of Latin America - following a successful pilot with surgeons in Mexico . He will be announcing the full results of the Latin American initiative at the Neuroendoscopy 2011 conference taking place in Guadalajara (Mexico). Dr Resch believes: “Ultrasound has been greatly underused in neurosurgery over the past 20-years,” and goes on to say, “I strongly advise all neurosurgeons to widen their imaging tools beyond just CT and MRIs. Intra-operative ultrasound can solve many problems that cannot be achieved with other imaging techniques. Dr Resch bases this recommendation on a 1084-patient case study on the uses of ultrasound in surgery – one third of which were observed intra-operative and two thirds peri-operatively. In this, he was able to prove conclusively that ultrasound was an excellent neuro-navigational system, which provided the surgeon with both real-time imaging and targeting capabilities in all of the intra-operative cases he observed (376 cases). In addition, it was also demonstrated that neurosurgical therapy outside the Operating Room could be markedly assisted by ultrasound.

For a number of years, Dr Resch has been a pioneer in the use of neurosurgical ultrasound and has discovered a broad variety of applications and indications both intra- and peri-operatively. He conducted his research using four bespoke ALOKA probes in a variety of settings – including the TCD probe (use: intensive care unit), the small part sector probe (use: intra-operative), and the burr-hole probe (use: intra-operative). The findings showed that ultrasound enabled the surgeon to be more reactive during surgery, with real-time images showing exactly how the lesion is being manipulated and how the brain reacts. In plain terms, this means the surgeon can view what is happening as he operates, without the need to stop the operation to obtain new images (i.e. from CT or MRI), which can be very dangerous for the patient. In addition, ultrasound is also preferable to CT or MRI during these cases as, with real-time images, there is no risk of error due to the brain shifting. Furthermore, the surgeon can also quickly locate vascular feeders and the source of any bleeding – a common and life threatening problem during operations. Additionally, Dr Resch has shown in Mexico that ultrasound could provide an invaluable surgical tool in the developing world, where the cost of procuring an MRI or CT scanner is highly prohibitive in comparison to an ultrasound unit. “Due to the cost-effective nature, logistical ease of use, and ergonomic character of ultrasound, it could have profound implications in the developing world and, this November, I will begin expanding my training programmes for neurosurgeons across all of Latin America. However, high-end neurosurgical ultrasound depends entirely on having selected the appropriate probes and ALOKA technology has been a big contributory factor in advancing its clinical uses.”
