This case example shows a routine fem-pop case where the surgeon assessed the quality of the bypass procedure using all 3 measurement technologies provided by the MiraQ system; High-Frequency Ultrasound (HFUS), Transit Time Flow Measurement (TTFM) and PW Doppler measurements.
Fem-pop bypass: Quality control with TTFM, HFUS and PW Doppler
Interoperative completion control
Image 1 shows a clear lumen and error-free proximal anastomosis. The flow was assessed using both TTFM and PW Doppler. The measurement shows acceptable flow volume with low PI, as well as a satisfactory flow velocity with corresponding Doppler spectrum at the proximal anastomosis, all indicating a patent graft. As seen in Image 2, TTFM of the proximal anastomosis during the case displayed a satisfactory flow of 328 mL/min with a repetitive corresponding flow curve.
