Benefits of Medistim technology in Carotid Endarterectomy published in EJVES

The CIDAC study is a prospective trial comparing high-frequency ultrasound (HFUS, named IDUS in the study) and angiography in 150 patients as intraoperative completion control after removal of plaque in a neck artery, a procedure called carotid endarterectomy (CEA).  The aim of a CEA procedure is to remove plaque that might become a source of embolism and cause stroke.

 The study was conducted by Professor Henning Eckstein and team at the well-recognized Klinikum Rechts der Isar (Technical University of Munich), Germany. For the HFUS scan, the Medistim VeriQ™ C device was used together with the L15 High-frequency Ultrasound Imaging Probe. 

 The results demonstrated that HFUS detected significantly more high-grade defects that needed revision compared to angiography, and with significantly higher interobserver reliability. The authors conclude that given the lesser invasiveness, HFUS could be considered as an alternative to angiography for intra-operative completion control in CEA.  

“This study further strengthens the support of using Medistim’s ultrasound imaging device and probe for reducing the risk of stroke after CEA” says Medistim President and CEO, Kari E. Krogstad. «The advantages with the use of ultrasound rather than angiography include no exposure to x-rays or contrast agents and no dependency on more costly angiography equipment.”
