A diagnostic breakthrough for monitoring blood perfusion in diabetics
Poor control of diabetes often leads to peripheral vascular complications, which are closely linked to foot ulceration and other chronic non-healing wounds.
But each patient has a unique vascular profile. So, without quantitative feedback on blood perfusion, doctors have to rely on educated guesswork – based on inadequate guidance from visual X-ray angiography – when carrying out treatment such as angioplasty.
The real-time deep tissue perfusion monitor uses a diffuse optical system to analyse the scatter pattern of coherent laser photons. This gives a picture of the movement of blood in all the blood vessels.
It’s simple to use – an adhesive sensor is attached to the patient’s foot and real-time perfusion data provides feedback during operative procedures.
The new technology helps reduce the risk of non-healing wounds, infection and limb amputation for diabetic patients. It also enables healthcare providers to cope with the increasing numbers suffering problems such as diabetic foot ulcers.
