Head-Up Display Assists CABG Vein Harvesting Procedures

An endoscopic visualization system uses a head-up display (HUD) via special goggles to place the endoscope view directly in the operator's field of view.

The Maquet Vasovision endoscopic visualization system is intended to help surgeons aim at saphenous veins during endoscopic vessel harvesting (EVH) procedures for coronary artery bypass graft (CABG). The system improves ergonomics in the operating room by providing crisp, clear, views of the working tunnel, and can eliminate the strain on the surgeon associated with poorly placed monitors or field of view challenges commonly found in operating rooms. Among the features of the display are ease of use and lightweight design, which make it comfortable for all users.

The system possesses fingertip adjustments on a pendant controller for image brightness and contrast, and a central viewing pane provides a wide field of view while enabling peripheral vision. The system kit includes a universal serial bus (USB) cable and USB charger, a video cable, the HUD viewer and the pendant controller, and an eyewear retainer. The Maquet Vasovision endoscopic visualization system is a product of Maquet Cardiovascular (Rastatt, Germany), and is designed to work with all of the company's Vasoview systems.

"We are strongly committed to further advancing EVH technology and conduit quality in bypass surgery. Vasovision is another example of our commitment to enhancing the procedure,” said Raoul Quintero, president and CEO of Maquet Cardiovascular U.S. Sales. "We believe we have developed an important visualization system that can help improve the operating room environment for clinicians wishing to perform EVH.”

EVH procedures replace traditional open saphenous vein vessel harvesting and avoid significant pain and discomfort for patients. In addition, the large incision that is required in an open vessel harvesting procedure is associated with a high rate of wound complications including dehiscence, hematoma, and infection. The endoscopic approach has a complication rate of less than 1%, compared to close to 15% with traditional open methods.
