Pneumatic Tourniquet In Endoscopic Radial Artery Harvesting

                                The Oxford Experience On How And When To Do It   

Objectives

Endoscopic radial harvesting (ERAH) is the second most common endoscopic harvesting technique at the Oxford Heart Centre. We are reporting the Oxford experience with the use of pneumatic tourniquet for ERAH along with technical and other considerations.

Method 

Prospectively collected data of ERAH were retrospectively analyzed

Standardised preoperative assessment using modified Allen’s test with pulse oximetry along with ultrasound scan of the radial artery and ulnar artery to determine diameter, flow, anatomical abnormalities, signs of atherosclerotic plaques, identify bifurcation & ensure adequate length.

The ERAH cases were divided into two groups and the results were directly compared. The technique of the tourniquet application along with tips and pitfalls were reviewed.

Results

ERAH was performed in 528 patients of which 307 were harvested using pneumatic tourniquets,

No post-operative compilations were recorded in both groups for the past two years. The full indications, techniques, and pitfalls in using the tourniquet for ERAH will be presented.

Conclusion

Endoscopic artery harvesting is a safe and reproducible technique. The use of a pneumatic tourniquet during ERAH is safe when used appropriately.
