Two-point flap blood glucose measurement for monitoring propeller flap perfusion – a case report

Abstract

Monitoring flap perfusion is a helpful method of postoperative care allowing for proper early intervention in and salvage of a flap. The basic means of blood supply monitoring include the assessment of color, warmth, skin tension, and a pin-prick examination. Along with advances in microvascular surgery, methods of flap blood circulation assessment have been also developed. This paper presents the case of a peroneal artery propeller perforator flap for the treatment of a secondary wound resulting from an orthopedic complication of ankle arthrodesis. Blood glucose level (BGL) was used to monitor flap perfusion as an early indicator of possible venous congestion. It is well known that in case of vascular compromise, whether arterial or venous, the flap salvage rate depends on how fast the vascular problem is resolved. Arterial insufficiency is easily detectable, and the arterial flow may be also monitored with minidoppler, however venous insufficiency causes symptoms less dynamically. This fact emphasized the importance of early prediction of venous insufficiency before clinical symptoms appear. It is crucial that the time between pedicle impairment and clinical signs is as short as possible.
