Real-time multispectral imaging for intraoperative monitoring of coronary artery bypass graft patency.

ABSTRACT:

Significance

Coronary artery disease is the leading cause of death worldwide, accounting for 16% of all deaths. A common treatment is coronary artery bypass grafting (CABG), though up to 12% of bypass grafts fail during surgery. Early detection of graft failure by intraoperative graft patency assessment could prevent severe complications.

Aim

We aim to evaluate multispectral imaging (MSI) as a non-invasive, contrast-free method for assessing graft patency during CABG surgery.

Approach

MSI was conducted at video rate during three CABG surgeries and two control surgeries. Two multispectral snapshot cameras captured images in the visible and near-infrared range. Tissue oxygenation and perfusion were derived using linear spectral unmixing and spectral indices.
