Hybrid ORs: not equally beneficial for all facilities

The hybrid operating room is one of the most innovative developments in the surgical sector. The combination of interventional and minimally invasive surgical procedures is exciting for many clinical disciplines. The room design, intraoperative imaging techniques as well as interdisciplinary collaboration play a pivotal role in this.

The vascular bypass revolution

Coronary or peripheral bypasses are the most frequently performed vascular operations. Although one million patients per year and around the world, undergo this intervention, its failure rate reaches 50%, because of poor vessel healing, leading to vessel graft occlusion.
