Flowmetry evolution in microvascular surgery: A systematic review

This review aims to provide a summary of the flowmeter devices used in microvascular surgery, and assesses their contribution to improving the clinical outcomes of free-tissue transfer. Flowmeters are widely accepted as the standard method of intra-operative assessment of the patency of coronary vascular anastomoses, providing thresholds that predict outcome. There is limited evidence regarding the use of flow measurements in Plastic Surgery microvascular anastomoses; however, flowmetry appears to have some role in post-operative free flap monitoring and prevention of complications.
