Using the rat groin model, five groups were evaluated: 1. flap isolation without division of the pedicle vessels (island flap); 2) flap isolation, division, and repair of the pedicle artery and vein (free flap); 3) flap isolation, with ligation of the pedicle artery immediately or 1 hour later; 4) flap isolation, with ligation of the pedicle vein immediately or 1 hour later; 5) flap isolation, with ligation of the pedicle artery and vein immediately or 1 hour later. The laser\u2010Doppler processes the signal by combination of the root mean square and differential amplification. The fluoroscan gives an index in relation to the fluorescence of a control area. The results obtained with both methods correlated well with findings in clinical situations. However, the laser\u2010Doppler readings were more rapid and sensitive than those with fluorometry. We suggest that laser\u2010Doppler velocimetry is a superior means of monitoring the vascular status of a free tissue transfer or digital replant.<\/jats:p>","DOI":"10.1002\/micr.1920100305","type":"journal-article","created":{"date-parts":[[2007,3,4]],"date-time":"2007-03-04T19:05:40Z","timestamp":1173035140000},"page":"170-174","source":"Crossref","is-referenced-by-count":5,"title":["Laser\u2010doppler versus fluorometry in the postoperative assessment of a cutaneous free flap"],"prefix":"10.1002","volume":"10","author":[{"given":"M.","family":"Durlik","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Benichoux","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Mainard","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Merle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,10,19]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"283","article-title":"Effets de l'ischemie transitoire sur le lambeau inguinal du rat.
