Ground-breaking technology pioneered at Guy’s and St Thomas’ Hospitals in London is using cloud computing to improve patient outcomes after surgery.

Cydar’s cloud software uses augmented reality to help surgeons navigate through blood vessels and accurately and safely place stents to treat blockages and aneurysms. Use of the software has been shown to reduce procedure time, the amount of a potentially harmful contrast dye used, and exposure of patients and staff to radiation from X-rays.

By connecting the live X-ray image in the operating room to the patient’s pre-operative CT scan, Cydar’s cloud software creates a 3D image of the blood vessels and displays it right in front of the surgeon, creating a GPS satellite navigation system for the vessels of the human body. This 3D technology has been shown to reduce operating times by 27%, radiation dose to staff and patients by 40% and the amount of kidney toxic contrast dye by 72%. Following an extremely successful trial, the system gained a CE mark in November 2015 and now has approval for sale within the European Economic Area.

Cydar was founded in 2012 by Tom Carrell, a vascular surgeon at Guy’s & St Thomas’ Hospitals, and Graeme Penney, an imaging scientist at King’s College London. Tom says:

“As someone who carries out keyhole endovascular surgery on a regular basis, I was acutely aware that giving physicians a clearer view of the anatomy could have a big impact on improving patient outcomes. Developments in computer vision are opening up really exciting opportunities to improve the visualisation and accuracy of surgery. It has been really exciting for our team to come up with a solution to this particular challenge, see it implemented and now helping patients.”
