- W2121128730 abstract "Although venous valve lesions have been cited as a mechanism of graft failure, the fate of venous valves in reversed saphenous vein (RSV) bypass grafts is unclear. The basis for this uncertainty is the difficulty in postoperative identification and follow-up of valve sites and the infrequent pathologic submission of vein graft lesions. This report describes the features of functional valves (FV) visualized in RSV grafts by ultrasonic duplex scanning.Sixty-six RSV infrainguinal vein grafts were prospectively studied with duplex ultrasonography from January 1992 to December 1995. Grafts were studied at 1, 2, 3, 4, 6, 9, 12, 18, and 24 months, then annually. FV identification was based on a characteristic ultrasound Doppler waveform and color flow pattern and visualization of the leaflets by B-mode imaging. The waveform consists of end-systolic valve closure followed by variable degrees of reflux. Immediate postoperative reactive hyperemia precludes detection, because flow reversal in the graft is needed for identification.Since August 1994, 14 FV have been identified in 11 (17%) of 66 RSV grafts. The mean time to FV recognition after implantation was 10 months (range, 1 to 52 months), and the average follow-up was 15 months. One valve was completely competent. Seven (50%) of the FV were associated with the development of a < 50% diameter reducing stenosis by Doppler velocity criteria. None of the FV has required intervention.Functional vein valves in RSV grafts are common and can be identified by ultrasonic duplex imaging. Awareness of the characteristics of FV during routine duplex graft surveillance will undoubtedly increase detection. The variable time course to identification of FV and duration of function warrants continued follow-up to determine the relationship of these valves to the development of stenotic lesions and graft failure." @default.
